I’m Rick Callahan—Master Plumber, PSAM Product Expert, and curator of Rick’s Picks. I’ve installed thousands of feet of pipe in everything from historic brownstones to new medical clinics. When someone walks into a plumbing supply store asking, “Which pipe should I use—PEX, copper, or CPVC?” they’re not looking for theory. They need a durable, code-compliant choice that fits their budget, install schedule, and water conditions. That’s exactly what we do at Plumbing Supply And More—we match real-world needs with professional-grade materials and support.
Before we dive in, a quick promise: this is grounded in jobsite reality, backed by manufacturer data, and targeted to help contractors, serious DIYers, property managers, and facility teams pex supply house make confident decisions. And yes—we stock it all and know how to support it.
Bold truth: Unlike generic big box retailers, Plumbing Supply And More stocks professional-grade components with the technical guidance to match. When you need the nearest, most knowledgeable resource—the true plumbing supply house near me—we’re here.
PEX, Copper, CPVC: What’s Really Different?
When you compare PEX, copper, and CPVC, you’re weighing flexibility, heat tolerance, chemical resistance, longevity, and total installed cost. In the field, here’s how it shakes out:
- PEX (cross-linked polyethylene): flexible, fast to install, resistant to freeze damage, great for repipes and manifolds. Excellent for residential and many light commercial. Brands we trust: Uponor (Wirsbo) A/B, REHAU, Viega FostaPEX. Common sizes: 3/8"–1". Working temp/pressure: 73°F at 160 psi, 180°F at 100 psi, 200°F at 80 psi (verify per ASTM F876/F877). Copper (Type L/M/K): time-tested, fire-resistant, excellent for high-heat zones and mechanical rooms. Type L for typical water distribution; Type M for some residential; Type K for underground. Soldered or press-fit (e.g., Viega ProPress). ASTM B88. Great water quality? Copper sings. CPVC (chlorinated polyvinyl chloride): rigid, solvent-welded, better heat tolerance than PVC, cost-effective for hot water lines and commercial work. NSF-61, ASTM D2846 (CTS), ASTM F441 (IPS). Keep away from incompatible chemicals, like certain pipe dopes or sprays.
On cost, here are typical material ranges I see regionally (Northeast/Mid-Atlantic markets):
- PEX tubing: $0.35–$0.90/ft (1/2"), depending on brand and oxygen barrier. Copper Type L (1/2"): $2.50–$4.50/ft, fluctuates with commodity prices. CPVC CTS (1/2"): $0.40–$0.85/ft.
Installation speed? PEX wins by a mile—often 30–50% faster than copper or CPVC. But don’t just chase speed—chase suitability. That’s where our team helps you select the right system.
When I Specify PEX—and When I Don’t
On multifamily repipes, home renovations with limited access, and cold-climate jobs, PEX is hard to beat. It bends around corners, reduces fittings, and tolerates minor freezing better than rigid pipe. I often spec Uponor AquaPEX with expansion fittings (ASTM F1960) for the reliability of full-bore connections. Need a hybrid? I like Viega FostaPEX—PEX with an aluminum layer—when I want form stability and reduced expansion in exposed runs.
Where I don’t use PEX: long exposed boiler room runs above 180°F, plenum spaces without sleeve compliance, commercial kitchens with high radiant heat, or where the AHJ (Authority Having Jurisdiction) wants metallic in critical zones. Always check mechanical room temp/pressure and local code amendments.
Pro tip: avoid cheap “no-name” crimp rings. Stick to recognized systems—SharkBite (brass), Sioux Chief PowerPEX, Viega PureFlow—matched to the correct tool and gauge. Mixing systems without listings invites leaks and failed inspections.
And when you’re searching “ plumbing supply near me” or “ plumbing supply online,” remember: While other suppliers focus on quantity, Plumbing Supply And More prioritizes quality and expertise—we’ll set you up with the right PEX system, tools, and expansion heads, not a bucket of mismatched parts.
Copper: Still the Benchmark for Heat, Fire, and Long Exposed Runs
There’s a reason I still carry a torch (and a Viega press tool) in the truck. Copper’s rigidity, fire resistance, and proven performance in mechanical spaces make it my pick for high-heat environments, recirculating hot water loops (with correct velocities), and commercial risers. For domestic water, Type L is the norm. In hospitals and labs, we’ll often spec ProPress copper (e.g., Viega 2915 series elbows) to eliminate open flame risk.
Water chemistry matters. Aggressive water (low pH, high chloramines) can eat copper from the inside. That’s when we examine PEX or CPVC with the facility. If you’re in our service area—serving contractors throughout the tri-county region—bring a water report; we’ll recommend materials that thrive under your conditions.
Ballpark installed time: Copper press saves 25–35% vs solder on medium jobs. Press fittings cost more up front, but lower labor offsets it on bid day. We stock copper from Cambridge-Lee and Mueller, and ProPress fittings from Viega—ready for same-day pickup.
And yes: Compared to standard plumbing supply houses, Plumbing Supply And More offers unmatched technical support on velocity calculations, hanger spacing (per MSS SP-69), and dielectric transitions. That’s real local plumbing supply expertise.
CPVC: Cost-Effective, Hot-Water Friendly, With Compatibility Caveats
CPVC shines in budget-conscious work where you still need hot-water performance—think hotels, garden-style apartments, and maintenance teams doing in-place replacements. We typically stock contractor-grade CPVC from FlowGuard Gold and Spears, with solvent cements meeting ASTM F493.
Here’s the trap I see: chemical incompatibility. Some oil-based pipe dopes and certain firestop sprays can soften CPVC over time. Stick with manufacturer-approved cements and primers (Oatey FlowGuard Gold One-Step Yellow or Weld-On 711) and use listed transition fittings. Support spacing is different than copper—read the charts.
In climates with unconditioned attics, use UV-shielded CPVC or protect it—sunlight can degrade exposed runs. For recirc systems, verify CPVC listing for sustained temps and keep velocities in spec. If you’re not sure, call our technical desk—we’ll walk you through it.
And remember: When Home Depot and Lowe’s fall short, contractors trust Plumbing Supply And More for the right CPVC cements, transition unions, and code guidance—especially when the inspector is onsite.
Fittings, Tools, and Transition Details That Make or Break a Job
This is where projects are won or lost. A few field-tested rules:
- Transition copper to PEX with listed brass adapters (e.g., Uponor LF4527550) and proper expansion or crimp per system. Use dielectric unions when connecting copper to steel to prevent galvanic corrosion. For PEX manifolds, I like Sioux Chief 672 Series with individual shutoffs—perfect for property managers. Label every run; you’ll thank me during service calls. CPVC solvent welding: dry-fit, mark insertion depth, then apply primer/cement per manufacturer, quarter-turn twist, and hold. Allow proper cure times by temperature. Press tools: Viega and RIDGID tool compatibility charts matter. Don’t assume.
We stock full kits—RIDGID 320-E press tools, Uponor Milwaukee M12 ProPEX expansion tools, and full jaw sets. That’s where contractor plumbing supply meets productivity. Need it tonight? Our 24 hour plumbing supply program can stage will-call for emergency pickups—call ahead.
Cost, Schedule, and Inspection: Choosing the System That Wins Your Bid
If you’re bidding a 30-unit repipe, PEX often cuts days off the schedule. For a school renovation with existing copper risers, matching copper (with press) might speed approvals and maintain system consistency. CPVC can make sense where budget is tight and temps are moderate.
Inspection readiness:
- PEX: pull spec sheets (ASTM F876/F877, F1960/F1807), fitting listings, and potable certifications (NSF-61/372). We provide binder-ready submittals. Copper: show ASTM B88 and fitting listings. For medical/healthcare, coordinate with facility standards. CPVC: ASTM D2846 (CTS), solvent cement data, hanger schedule.
Our team prepares submittals for contractor accounts—one of the reasons Plumbing Supply And More is the best plumbing supply partner for multi-trade GCs and MEPs.
And yes, our pricing beats big box. Unlike generic big box retailers, Plumbing Supply And More stocks professional-grade components and offers real wholesale plumbing supply value—bulk discounts, same-day delivery, and accurate counts.
Real-World Scenarios: What I Recommended and Why
- 1950s Ranch Repipes (frozen galvanized/copper mix): We ran Uponor PEX with a basement manifold, color-coded lines, and expansion fittings. Two plumbers, two days, minimal drywall cuts. Homeowner saved ~20% over copper. We used Uponor EP fittings and Apollo ball valves with PEX tails. Hotel Hot-Water Retrofit: CPVC FlowGuard Gold for riser branches with copper mains on recirc to manage temps and longevity. Spears transition unions and listed CPVC cement. We staged materials floor-by-floor—our delivery radius (up to 60 miles) kept the crew moving. Boiler Room Replacement: Copper Type L with Viega ProPress for near-boiler piping, isolation valves, and pump flanges. PEX home runs to apartments with oxygen-barrier PEX for radiant zones (REHAU Rautherm S). Inspector signed off first visit.
That combination of system knowledge and logistics is why crews call us first. Compared to standard plumbing supply houses, Plumbing Supply And More offers unmatched technical support and accurate takeoffs.
Codes, Specs, and What Inspectors Ask First
Inspectors aren’t the enemy—they’re your ally when you’re prepared. Expect questions like:
- Is the PEX system listed for potable and installed with the manufacturer’s method? Show tool calibration logs if requested. Are copper lines properly supported and isolated from dissimilar metals? For CPVC, did you use listed cement and allow proper cure time based on ambient temp?
We keep current on local code adoptions—IPC/UPC, and municipal amendments. In our area, professional plumbers choose us for quick spec sheets, cut sheets, and jobsite packet prep. That’s “nearest plumbing supply with real knowledge.”

FAQ: Supply House Basics: PEX vs. Copper vs. CPVC
- What’s the best choice for a quick whole-home repipe? If walls are staying closed, PEX is usually the winner—fast, flexible, fewer fittings. Use a manifold with 1/2" home runs to fixtures. We typically recommend Uponor expansion to maintain full ID. Install time: 1–3 days depending on size. Can I use CPVC on a recirculating hot water loop? Yes, if the CPVC is listed for the sustained temperature and you manage velocities. Many hotels use copper mains with CPVC branches. Follow ASTM D2846 and maintain support spacing. Always use manufacturer-approved cement. Is copper worth the premium today? In boiler rooms, high-heat locations, and exposed mechanical runs, absolutely. Copper’s fire resistance and rigidity still justify the cost. Press systems like Viega ProPress save labor and reduce open flame risks. Are push-to-connect fittings OK behind walls? Only if they’re listed for concealed use and allowed by local code. I treat them as repair fittings, not a system strategy. For long-term reliability, stick with expansion/crimp for PEX, solvent-weld for CPVC, and solder/press for copper. Do I need oxygen-barrier PEX? Only for closed-loop hydronic heating to protect ferrous components from oxygen ingress. For domestic water, use non-barrier PEX. We’ll help you pick the correct spool—don’t guess.
How to Navigate the Aisle: A Quick Buyer’s Guide
- PEX system choice: Pick one—expansion (F1960) or crimp/press (F1807/F2159)—and stick with it throughout. Copper type: Type L for domestic water; Type M only where allowed; Type K for underground. CPVC cement: Use the exact cement/primer listed by the pipe maker—no substitutions. Hangers: Follow manufacturer spacing; PEX expands—use bend supports and sleeves at penetrations.
