The basement lights were on, the washer was mid-cycle, and then the unmistakable sound—gurgling through a floor drain—announced trouble. Water was rising along a foundation wall, the sump was cycling like crazy, and nothing meaningful was leaving the pit. Diagnosis: a mismatched discharge line choking a hard-working Myers sump pump. I’ve seen that failure pattern hundreds of times—excellent pump, undersized or poorly built discharge pipe. Result? Overheating, shortened service life, and a basement that smells like a wet cardboard warehouse.
Two streets south of Main in Brattleboro, Vermont, I met the Saldivar family: Luis (39), an HVAC tech who isn’t afraid of PVC glue; his partner, Kelly (36), a school counselor with a sharp eye for water stains; and their kids, Mariah (10) and Gabe (7). During spring thaw, their previous brand sump ran nonstop, yet the yard discharge was a dribble. The culprit was a 1-1/4" line with too many elbows feeding a long run uphill—zero chance the pump could keep up during peak melt. Once we spec’d a Myers sump with the right horsepower and a properly sized discharge line, the pit cleared like clockwork.
This guide walks you through the exact decisions that keep basements dry—and your Myers pump healthy. We’ll size for flow, pick pipe materials, set the right discharge size, choose an outdoor termination, add a check valve, plan freeze protection, manage long runs, and integrate smart fittings. We’ll also cover quiet-operation tricks, code compliance, and installation pro tips—everything rural homeowners, contractors, and emergency buyers need to get water moving out and away, fast.
Plumbing Supply And More (PSAM) stocks the parts that pair perfectly with a Myers Pumps sump system. And yes—Myers is backed by Pentair engineering, with premium design features proven in hard water and tough duty cycles. Good pumps deserve good piping. Pair them correctly and your basement stays dry, season after season.
#1. Start with Flow and Head – Match GPM to Pipe Diameter and Total Run Length
Undersized discharge pipe is the number-one reason I see top-tier pumps struggle. If the pipe can’t pass your pump’s GPM rating, the system throttles itself and wastes energy.
A properly selected pipe diameter—matched to pump discharge, run length, and elevation—keeps friction losses in check and lets the Myers sump work at its sweet spot. Start with the pump curve and real-world head: vertical rise plus equivalent feet for horizontal and fittings. A typical 1/3 HP sump pump may push 35–45 GPM at 5 feet of head; that same unit can drop below 25 GPM at 15 feet with small-diameter pipe and too many bends. Right-sizing the line keeps the pump near its best performance zone and reduces run time—less heat, longer life.
The Saldivars had 18 feet of equivalent head with their up-and-over routing and tight elbows. Luis swapped the old line for a smooth, sweeps-based setup and bumped the diameter to match target flow. Result: shorter cycles and a pit that actually stayed empty.
Calculate Real Head, Not Just Vertical Rise
Don’t stop at measuring the basement-to-outlet rise. Add equivalent feet for every elbow and long run:
- 90-degree elbow = ~5–8 feet of equivalent length, depending on radius 45-degree elbow = ~2–3 feet Corrugated exterior pipe can double friction; avoid for long runs When you add these to your vertical lift, you get the true head the pump sees. That number is what matters.
Pump Curve Meets Pipe Tables
Use the Myers performance tables and pipe-friction charts together. Target a line size where friction loss stays well below the pump’s capacity at your design flow. For long runs over 60 feet equivalent length, consider upsizing one pipe nominal size for safety margin.
Pro Tip: Keep Fittings Gentle
Every hard turn hammers efficiency. Use long-sweep 90s or two 45s with a short nipple between. I also prefer solvent-weld fittings over barbed couplings for smoother interiors and better long-term seal.
Key takeaway: Fit the pipe to the pump’s true workload. Your Myers moves water; the right pipe keeps it moving.
#2. Choose the Correct Discharge Size – 1-1/2" NPT Threads and Why It Matters
Myers sump pumps commonly feature a 1-1/2" NPT discharge. That’s your starting point—not a suggestion. Reducing immediately to 1-1/4" is a guaranteed way to spike friction losses and starve your flow.
A 1-1/2" line carries far more myers sump pump GPM with less head loss than smaller pipe. Even if a smaller tube “fits,” the cost is backpressure, longer run times, and more heat in the motor. Over time that’s what eats insulation and seals. Keep the first section at full diameter for at least 8–10 feet before any transition. If you must adapt, use a tapered reducer with a smooth interior—never a quick crimp to undersize tubing.
For the Saldivars, the change from 1-1/4" to a full discharge size of 1-1/2" on the first 12 feet boosted flow dramatically. The pit cleared 40% faster during the next storm.
Why 1-1/2" Wins in Real Basements
At 35–45 GPM, 1-1/2" PVC keeps velocity moderate, which reduces friction losses and noise. Lower velocity also means fewer water-hammer incidents when the check valve snaps shut. Less noise, less wear—win-win.
Adapters the Right Way
Use a thread-to-slip adapter rated for pressure at your sump’s duty. Wrap the 1-1/2" NPT male with PTFE tape, then thread into the pump outlet carefully. Don’t overtighten; you’re sealing threads, not bending metal. Then solvent-weld to rigid PVC for a stable riser.
Don’t Forget the Riser Geometry
Keep that first riser plumb and supported. A crooked riser loads the pump’s discharge neck and can cause fatigue at the threaded connection over time.
Key takeaway: Respect the factory outlet size. Your Myers runs cooler and empties faster with a true 1-1/2" path.
#3. Pick the Right Material – Smooth-Wall PVC vs Corrugated vs Thermoplastic Hose
Pipe material choice sets the tone for friction, durability, and freeze risk. Smooth-wall PVC wins for interior runs; cheap corrugated or flexible thermoplastic hose is for temporary setups, not permanent protection.
Rigid Schedule 40 PVC offers a smooth interior that reduces friction and resists collapse under partial vacuum conditions that can occur during rapid pump starts. Flexible hoses are convenient, but their ridges can double friction at sump velocities. Over long runs, that can cut effective flow by 25–40% and lengthen cycle times.
When Luis and Kelly replaced their corrugated exterior run with rigid PVC to a daylight termination, the Myers unit cleared the basin consistently—even during peak melt.
When to Use Flexible Line
Use flexible hose only for:
- Short vibration isolators near the pump Temporary emergency bypasses Tight retrofits where one offset is unavoidable If you must run flexible, upsize one diameter to offset higher friction, and clamp with stainless bands.
PVC Joints and Solvent-Weld Technique
Clean and prime both fitting and pipe. Apply an even solvent layer and a full-depth push with a quarter-turn twist. Hold for 10 seconds to prevent pushback. Proper joints are as strong as the pipe.
UV and Yard Exposure
Exterior PVC exposed to sunlight becomes brittle over years. Paint above-grade PVC with exterior latex or wrap it. For buried lines, bed in sand and avoid rocks that nick the pipe.
Key takeaway: Use smooth-wall PVC for permanent sump discharges; flexible is for short, specific needs only.
#4. Check Valves and Air Relief – Keep Water Moving One Way and Prevent Air Lock
No discharge plan is complete without a properly oriented check valve and a small air-relief hole to prevent vapor lock. Without these, water can surge back to the pit on every stop—and the pump can spin without moving water.
Place a quality inline swing or spring check directly above the pump or at least within 2–3 feet on the vertical riser. Orient the arrow with flow. Drill a 3/16" weep hole in the riser below the check valve (inside the pit) to vent trapped air on startup. That tiny hole solves 90% of mysterious “pump runs but no flow” calls I take every spring.
We installed a heavy-duty check in the Saldivars’ riser and drilled the relief just above the waterline. Their Myers snapped on, purged instantly, and moved water on the first rotation—every time.
Swing vs Spring
- Swing checks are common, quiet, and low restriction for high GPM systems. Spring checks hold closed with a light spring—useful on tall risers where backflow is a problem. Choose a full-bore design that matches your pipe size to avoid added friction.
Weep Hole Placement Matters
Drill at a slight downward angle to minimize spray. Keep it below the check so the line above remains primed. If the pit mist bothers you, install a short deflector inside the crock.
Service Access
Include a union or quick connect system above the check. This makes pump replacement simple and avoids hacksaw surgery down the line.
Key takeaway: One valve, one tiny hole—massive reliability gain for any Myers sump system.
#5. Long Runs and Elevation – Upsize Strategically and Use Gentle Geometry
Long horizontal runs, high vertical rises, and multiple direction changes are where discharge designs go to die. Fight friction and velocity with larger pipe, sweeping turns, and clean routing.
For any equivalent run exceeding 50–60 feet or vertical rise beyond 12 Myers well pump specifications feet, consider upsizing one diameter after the first 10 feet. Transition with a smooth reducer and re-check velocity using a pipe-friction chart. The goal is keeping velocity in the 4–6 ft/s range to prevent hammer and cut noise. Too fast and you’ll hear it; too slow and solids can settle at low points.
Luis’s original path ran up 9 feet, across 25 feet, then up another 3 feet to daylight. We rebuilt with a 1-1/2" riser, transitioned to 2" at the joist, then sloped gently to the exit. Flow improved, cycles shortened, and the motor ran noticeably cooler.
Eliminate Traps and Sags
Support horizontal runs every 4–5 feet to avoid bellies that collect water. Water pockets cause start-up hammer and can freeze. Use rigid hangers and maintain consistent pitch to the exit.
Two 45s Beat One Hard 90
Friction loss compounds at tight turns. Two 45-degree elbows with a short nipple between cut turbulence and keep flow energy working for you, not against you.
Test Under Storm Load
Run a controlled fill and time the emptying cycle. If your pump takes longer than its rated curve suggests, reduce fittings or upsize again. Better to optimize on a dry day than during a storm.
Key takeaway: For long or high routes, bigger, smoother, and straighter always pays off.
#6. Exterior Termination – Daylight, Dry Well, or Storm Tie-In with Code Compliance
Where the line ends is as important as the path it takes. Discharging too close to the foundation or into sanitary systems is a recipe for recirculation, fines, or both. Plan the outlet for legal, effective drainage.
Best practice is to daylight on a slope at least 10 feet from the foundation. Use a splash block or energy diffuser to prevent erosion. Where soils are poor, a dry well with washed stone and geofabric can handle bursts. Some municipalities allow storm tie-ins; very few allow sanitary connections—don’t risk it.
For the Saldivars, we daylighted on the downslope and added a diffuser. Their lawn stayed intact, and water didn’t creep back toward the foundation.
Freeze-Safe Outlets
Northern installs need freeze awareness. Terminate with a down-facing elbow 8–12 inches above grade or use a buried outlet with a freeze-resistant pop-up. Standing water in a flat outlet will ice up and block the line.
Rodent and Debris Protection
Use a screened termination that resists clogging. Avoid fine mesh that mats with leaves. A coarse grid that sheds debris while preventing critter entry is best.
Sewer and Cross-Connection Prohibitions
Never connect to sanitary lines. Besides being illegal in most jurisdictions, it invites sewer gas and backflow contamination. Review local code—PSAM can point you to typical regional requirements.
Key takeaway: Legal, slope-friendly, and freeze-savvy outlets keep your Myers system dependable year-round.
#7. Freeze Protection – Slope, Air Breaks, and Cold-Weather Materials That Don’t Quit
Freeze-ups can silence a perfect pump. Preventing ice is about drainage, slope, and materials. Any trap holding water outdoors becomes a popsicle that blocks flow and overheats the motor.
Slope exterior lines continuously to daylight. Avoid low spots. Outside, use rigid PVC that doesn’t collapse under snow load. Where lines cross frost zones, bury below frost depth or wrap with insulation rated for ground contact. If the line must rise before discharge, include a small air-admittance hole just inside the building envelope to let water drain back.
Kelly noticed their previous outlet froze every January. We rebuilt with continuous fall to a down-facing elbow. The line now drains dry between cycles—no ice, no backpressure.
Weep Strategy in Cold Climates
A 3/32" relief hole just inside the wall can let exterior runs drain. Keep it minimal to avoid noise and mist. Pair with a serviceable plug if needed off-season.
Buried Lines
If you must bury, bed the pipe in sand, maintain continuous slope, and mark the route with tracer tape. Pop-up emitters need maintenance—flush seasonally and check for lawn thatch build-up.
Material Choices in the Cold
Schedule 40 PVC handles cold snaps well when supported. Flexible hose stiffens and cracks over time in UV and cold. Use it sparingly.
Key takeaway: If water can sit, it can freeze. Design to drain, not to hope.
#8. Quiet, Clean, and Serviceable – Unions, Hangers, and Vibration Control
A well-built discharge line doesn’t rattle joists or thump when the check valve closes. Quiet equals quality. Inline unions and smart supports make maintenance painless and keep noise down.
Install a union or quick connect system above the check valve and another near the exit if access is tricky. Use cushioned clamps every 4–5 feet on horizontal runs and within 12 inches of every elbow to prevent resonance. Soft mounts at the pump base also help. Keep the first riser plumb and braced; sloppy risers knock and fatigue threads.
Luis, being an HVAC tech, loved this part—clean unions, straight riser, cushioned hangers. Kelly noticed the difference the first night: no more midnight thuds.
Water Hammer Taming
A full-port swing check and slower velocity reduce slam. If hammer persists, upsize the section above the valve or add a vertical arrestor stub. Keeping velocity around 5 ft/s is your best friend.
Service Clearances
Leave room for hands and tools around the valve and union. You’ll thank yourself during the next maintenance cycle. Label the line and note the weep-hole position on a tag.
Clean-Out Thoughtfulness
Add a threaded clean-out near the exit on long exterior runs. When spring brings silt, a 5-minute flush beats digging.
Key takeaway: Build like a pro—quiet, accessible, and future-proof.
#9. DIY vs Pro – Electrical, 115V Motors, and When to Call PSAM for a Kit
Many homeowners can build a solid discharge line. The decision point is complexity: long runs, frost concerns, or a sump that also handles perimeter drain inflow may call for a contractor. Pairing pipe sizing correctly with a Myers motor—often 115V on residential sumps—keeps performance on spec.
PSAM stocks complete fittings kit options matched to common Myers Pumps models, plus unions, valves, and solvent-weld components that save trips. We’ll size the discharge and select hangers, reducers, and terminations based on your layout and expected GPM rating. If your line runs over 60 feet or exits through a complex foundation, get us a sketch. We’ll return a parts list and a game plan.
For the Saldivars, I recommended a DIY build with our materials list; Luis executed like a pro and saved a service call, while Kelly handled permits and yard layout.
Electrical Safety First
Even if you run the pipe, bring in a qualified electrician if you’re not comfortable with receptacle installation or GFCI protection. Sump circuits deserve their own breaker and dry, elevated outlets.
Kit Advantages
A curated kit avoids mismatched threads, wrong cement/primer, or under-spec valves. You’ll get unions where you need them and a valve that actually seals.
Inspection and Local Compliance
Some jurisdictions require permits for exterior discharge changes. A quick call avoids red tags later.
Key takeaway: Don’t guess—plan. PSAM’s kits and guidance make a Myers install smooth and safe.
#10. Why Myers Sumps Pair Best with Proper Discharge – Materials, Warranty, and Brand Backing
A premium pump can’t mask a bad discharge line, but a premium pump rewards a great one. Myers sump systems—born from the same engineering DNA as the Predator Plus Series—use robust components, including stainless fasteners and durable housings, engineered to run cool on tough cycles. Pair that with a correctly sized, low-friction discharge, and you’ve got a basement that stays dry through spring storms and summer cloudbursts.
Myers’ build quality shows up in the details: components echo the corrosion resistance you see in 300 series stainless steel well pumps, and the brand brings Pentair R&D to the table. Add the industry-respected 3-year warranty—and you’ve got support that outlasts trend brands.
The Saldivars switched to a Myers unit, optimized the line, and their system has now run through two melt seasons without a hiccup—short cycles, quiet operation, clean yard exit.
Myers + Right-Sized Pipe = Efficiency
A pump near its best-efficiency zone runs fewer minutes per hour. That means cooler windings, longer seal life, and less wear on the check valve. The discharge line is part of the “motor health plan.”
Corrosion and Seal Integrity
Good piping keeps backpressure in line and water away from critical interfaces. Just like our submersible line benefits from stainless metallurgy, the sump ecosystem benefits from corrosion-smart design choices.
Support That Shows Up
At PSAM, we ship fast, stock the parts that match, and help you troubleshoot. A premium pump with premium support makes storms boring—which is exactly what you want.
Key takeaway: Myers plus a purpose-built discharge line is the quiet workhorse you’ll forget about—until it saves your basement.
Competitive Reality Check: Myers vs Alternatives in the Sump and Discharge World
Some brands focus on quick installs or budget materials that look fine on day one but struggle under seasonal surges. Here’s where the discharge line amplifies differences.
1) Technical performance. Many budget packages ship with narrow, flexible hose that spikes friction. Myers systems expect a full-bore 1-1/2" rigid run to preserve designed capacity. Where certain Wayne Pumps kits lean on light-duty flex lines and barbed couplings, Myers shines when paired with solvent-weld PVC and full-port valves. A rigid, smooth path lets the motor run cooler at real-world head, protecting windings and seals.
2) Real-world application. A quiet check valve and right-sized pipe make basements livable. I’ve seen homeowners fight water hammer and loud shutoffs in flex-only setups. Myers with a solid PVC riser, cushioned hangers, and a weep hole behaves like a system, not a project.
3) Value conclusion. Between reliable cycles, fewer callbacks, and a 3-year warranty, the Myers approach is worth every single penny.
Another angle worth noting involves Zoeller systems. They build dependable pumps; I respect their castings and durability. Where I see projects veer off course is installers defaulting to small-diameter corrugated hose outdoors. Zoeller pumps will do their job, but discharge losses kneecap performance. The Myers + PSAM method standardizes the pipe sizing conversation, prioritizes smooth bore rigid lines, and bakes in proper check valve selection. On seasonal peaks, that difference keeps basements dry and run times low. With Pentair backing and PSAM’s in-stock unions, valves, and adapters, total ownership cost drops—again, worth every single penny.
FAQ: Discharge Piping and Myers Pump Performance
1) How do I determine the correct horsepower for my well depth and household water demand?
For wells, horsepower depends on total dynamic head (well depth + elevation + friction) and required flow. Typical homes need 8–12 GPM. A 1/2 HP submersible often handles 60–120 feet; 3/4–1 HP goes deeper and supports higher demand. For sump systems, horsepower selection focuses on head (vertical rise and pipe friction) and storm inflow. If your vertical lift is 8–12 feet with 40–60 feet equivalent length, a 1/3 to 1/2 HP Myers sump is common. Consult the pump curve: at your head, verify the GPM rating meets your inflow. Rick’s recommendation: Size for the heaviest storm you’ve seen, with 10–20% headroom. PSAM can translate your line layout into a head estimate and point you to the right Myers model.
2) What GPM flow rate does a typical household need and how do multi-stage impellers affect pressure?
Most households thrive at 8–12 GPM continuous for domestic use; irrigation needs can double that. In well systems, multi-stage impellers increase pressure by stacking energy across stages, enabling deeper TDH without huge motors. In sump applications, stages aren’t the focus—single-stage centrifugal designs move large volumes at lower heads. What matters is pairing the pump’s curve to your discharge friction and elevation. Keep the first 10 feet of discharge at full discharge size, avoid hard 90s, and ensure the check valve is full-port. My field note: correct piping often boosts net throughput more than a jump in horsepower.
3) How does the Myers Predator Plus Series achieve 80% hydraulic efficiency compared to competitors?
In the well world, Myers’ Predator Plus Series leverages precision-matched impellers and diffusers, plus tight hydraulic tolerances and engineered materials to hit 80%+ at the best efficiency point. Durable components reduce internal leakage and recirculation losses. That same manufacturing discipline informs Myers sump pumps—smooth hydraulics, correct port sizing, and robust seals. Translate that to your basement: a low-friction discharge line lets the motor operate near its ideal zone, minimizing heat and boosting lifespan. Rick’s tip: whether it’s a deep-well submersible or a basement sump, the pipe is part of the efficiency system.
4) Why is 300 series stainless steel superior to cast iron for submersible well pumps?
For submersibles, 300 series stainless steel resists corrosion from minerals and mildly acidic conditions better than cast iron. It maintains dimensional stability over time, which protects impeller clearances and shaft alignment. That’s why Myers well platforms last longer in challenging aquifers. While sumps aren’t submerged in drinking water, corrosion resistance still matters—fasteners, clamps, and discharge fittings live longer when rust doesn’t creep in. In my experience, corrosion steals performance quietly; stainless components protect long-term efficiency across pump families.
5) How do Teflon-impregnated self-lubricating impellers resist sand and grit damage?
In abrasive wells, engineered impellers with self-lubricating surfaces shed grit and reduce galling. Minimizing friction and wear preserves pump curves over years instead of months. Myers’ well technology has proven that approach. In sump systems, debris management starts with a good pit screen and smart discharge choices. Smooth-wall PVC doesn’t trap fine silt like corrugated lines do, and sweeping fittings keep solids moving. Rick’s advice: good hydraulics plus clean intake equals longevity—whether the medium is sandy groundwater or storm runoff.
6) What makes the Pentek XE high-thrust motor more efficient than standard well pump motors?
High-thrust designs stabilize axial loads from stacked impellers, reducing bearing wear. Precision windings, optimized rotor geometry, and thermal protection keep current draw in line and the motor cooler. While a sump motor is a different animal than a deep-well unit, the lesson carries over: run at the sweet spot on the curve with minimal discharge restriction. Cooler motors live longer—simple as that. Keep your discharge line full-size, use a gentle path, and your 115V Myers sump will thank you with quiet, reliable service.
7) Can I install a Myers submersible pump myself or do I need a licensed contractor?
Submersible well pumps generally require a licensed contractor—there’s lift equipment, electrical splices, and health code considerations. Sump discharge lines, however, are prime DIY territory if you’re comfortable with measuring, cutting, and solvent-welding PVC. Use a fittings kit matched to your pump, install a quality check valve, and follow local codes for exterior termination. If you’re adding a new circuit or GFCI-protected outlet, hire an electrician. PSAM can supply parts and a layout so you don’t guess on diameters or fittings.
8) What’s the difference between 2-wire and 3-wire well pump configurations?
In wells, 2-wire units house start components in the motor; 3-wire units use an external control box. Each has pros and cons for diagnostics and replacement cost. For sumps, you’re usually dealing with single-phase, direct-plug motors at 115V or 230V with integral float controls. The discharge principles overlap: less restriction equals better operating current and cooler windings. Rick’s rule: pick the right control architecture for wells, but never neglect discharge geometry for sumps. Both make or break system longevity.
9) How long should I expect a Myers Predator Plus pump to last with proper maintenance?
In clean wells with proper sizing and voltage, premium Myers submersibles routinely deliver 8–15 years, with longer spans not uncommon. Maintenance includes pressure tank checks, voltage verification, and periodic water quality assessments. For sump pumps, life depends on run frequency, debris load, and discharge restriction. A properly piped Myers sump with a clean pit, full-size discharge, and smooth fittings can run reliably for many years—often beyond the “average” homeowners experience with budget pumps. Keep velocity reasonable and the check valve healthy; you’ll be happy with the lifespan.
10) What maintenance tasks extend well pump lifespan and how often should they be performed?
For wells: inspect the pressure system annually, verify switch settings, test amperage against nameplate, and review water quality for sand or iron that can damage components. For sumps: vacuum debris from the pit twice a year, test-run monthly, confirm the weep hole is clear, and look over hangers and unions. Cycle the pump during rain to verify the exterior outlet isn’t obstructed by mulch or snow. Rick’s recommendation: put these checks on your spring and fall to-do list.
11) How does Myers’ 3-year warranty compare to competitors and what does it cover?
Myers’ 3-year warranty outpaces many sump and well competitors that stick to one year. Coverage targets manufacturing defects and performance failures under normal use. When paired with PSAM’s support and parts availability, downtime shortens dramatically. I’ve seen homeowners save hundreds in repeat costs thanks to that warranty window—especially when the discharge and installation followed best practices. Contrast that with short warranties: a single out-of-warranty failure can erase any upfront “deal.”
12) What’s the total cost of ownership over 10 years: Myers vs budget pump brands?
Account for energy, replacement frequency, labor, and avoided water damage. Budget pumps can last 2–4 years in tough applications, often paired with undersized corrugated discharge lines that inflate run times. Myers paired with a smooth, full-size discharge line runs fewer minutes per cycle, keeps windings cooler, and reduces risk during peak storms. Over a decade, the extra service life and support—plus PSAM’s ready-to-ship parts—translate into fewer panicked nights and fewer receipts. My field math says the Myers route is, simply, worth every single penny.
Conclusion: Your Myers Sump Pump Is Only as Good as Its Discharge Line—Build It Right
A great pump with a restricted discharge is like a pickup with square wheels—it’ll move, but not for long. Give your Myers the full-diameter, smooth, well-supported path it deserves. Start with accurate head, keep that first 10 feet at 1-1/2", pick smooth-wall PVC, add a smart check valve and relief hole, plan a freeze-proof termination, and support everything with unions and cushioned hangers. That’s the PSAM blueprint I’ve used for years to keep families like Luis and Kelly Saldivar’s basement dry through the worst melt and rain.
