I’ve laid out thousands of feet of pipe on new builds—from custom homes off Lake Murray to mixed‑use buildings downtown—and the same truth holds: new construction doesn’t forgive sloppy planning or mediocre materials. If you’re a GC, a journeyman, or a serious DIY owner-builder, your supply chain can either keep you ahead of schedule or cost you change orders and callbacks. This guide pulls from my 25+ years on job sites and behind the counter as Product Expert at Plumbing Supply And More (PSAM), where my “Rick’s Picks” lineup is built on real field performance, not glossy spec sheets.
You’ll see me reference real models, actual price ranges, and what I’d put in my own projects. You’ll also see why contractors in our region rely on PSAM: our inventory is deep, our technical support is real, and we don’t disappear when the inspector pulls up. Let’s get into the plumbing supply essentials that keep new construction moving—without surprises.
Why New Construction Lives or Dies by Supply Strategy
New construction is a choreography of trades. Plumbers set the rhythm early: slab rough, top-out, fixture set. If you blow your rough package or misjudge lead times, framers idle, electricians wait, and GC margins evaporate. I’ve watched jobs lose days because a supplier shipped “equivalents” that didn’t match the submittals. Not on my watch.
Here’s my core approach: lock your rough-in package up front, verify submittals against local code and spec, and stage the project in three drops—rough, top‑out, and trim. At PSAM, we set contractor accounts with phased delivery, labeled pallets by unit/stack, and QR-coded packing lists so supers can track every elbow and escutcheon.
And yes, I’ll say it plainly: Unlike generic big box retailers, Plumbing Supply And More stocks professional-grade components—no bait-and-switch SKU games. When Home Depot’s aisle ends, the job shouldn’t.
Pro tip: For slab-on-grade, I always over-order schedule 40 PVC DWV fittings by 5% and PEX-A expanders by 2 heads per crew. The “extras” you carry now are cheaper than re-mobilizing tomorrow.
Core Rough-In Materials: Pipe, Fittings, and Hangers that Pass Inspection
Your rough-in package sets your inspection outcome before you pull your tape. For 2‑story wood frame with slab, here’s my go‑to:
- Pressure water: Uponor PEX‑A (AquaPEX), color-coded, 1/2", 3/4", and 1". I spec expansion fittings with ProPEX rings. Expect $0.40–$0.95/ft for 1/2"–1". Tooling: Milwaukee M12/M18 ProPEX Expanders with Quick-Cam. Manifolds: Uponor EP Flow-Through or Viega ManaBloc (for engineered PEX‑B systems). Label each port with zone and unit. It saves service calls. DWV: Charlotte Pipe PVC DWV, Schedule 40, solvent weld with Oatey Heavy Duty Gray cement and Purple primer (yes, inspectors want to SEE the purple). Gas: If allowed, TracPipe CSST CounterStrike with bonding clamp per NFPA 54 and local amendments. Natural gas design at 0.5" WC pressure drop unless the AHJ directs otherwise.
Hangers and supports: Performance matters. Use Sioux Chief or HoldRite clamps and insulators. Firestop: Hilti or Specified Technologies (STI) systems with UL listings per penetration type. Label firestops; inspectors love seeing UL system numbers right on the sleeve.
We preload PSAM rough-in kits by stack—labeled “Riser A, Units 101–104”—so crews aren’t rummaging. And when you need 4" x 3" PVC closet bends at 6:30 am, Compared to standard plumbing supply houses, Plumbing Supply And More offers unmatched technical support—and yes, our dock opens early.
Water Distribution: PEX vs. Copper vs. CPVC—What I’d Choose and Why
I get this one constantly: “Rick, should I run copper to future‑proof the building?” For most residential and light commercial in our area, I specify PEX‑A with home-run or sub‑manifold zoning. Why?
- Freeze resilience: PEX‑A handles expansion stresses far better than Type L copper. Speed and consistency: Expansion joints are full-flow, reducing restriction and stagnation. Fewer joints in concealed spaces: Less risk, faster top-outs.
Copper still has its place: mechanical rooms, risers subject to high temps, and where spec or HOA demands it. If so, Type L hard copper with lead-free solder and water-soluble flux. Verify water chemistry—aggressive water can eat thin-wall copper.
CPVC? It’s code-legal in many jurisdictions, but for new construction, I use it selectively (hotel risers, some multifamily with careful hanger strategy). Temperature/impact sensitivity can be unforgiving during fast builds.
We stock Uponor, Viega, and NIBCO Press systems. Milwaukee M12 Force Logic press tools speed copper installs with fewer burn permits. And here’s the quiet win: PSAM tracks calibration dates and will loaner-swap your expander or press tool if it throws errors, minimizing downtime. While other suppliers focus on quantity, Plumbing Supply And More prioritizes quality and expertise—we support the tools that drive the supplyhouse your schedule.
Drain, Waste, Vent and Slope: Silent Systems and Code-Safe Layouts
DWV is where rookies get caught. Three themes matter: slope, venting, and sound control.
- Slope: 1/4" per foot for 2.5" and under; 1/8" per foot for 3" and up (check local amendments). Over‑slope can cause trap seal issues just as easily as under‑slope causes clogs. Venting: Re‑vent island sinks with AAVs only if your AHJ allows; I prefer true vents through the roof. Studor is the reputable AAV if used. Quiet: In multifamily, use Charlotte Quiet House or cast iron (service weight) stacks for baths adjacent to living spaces. No one wants a midnight flush soundtrack.
Transition gaskets: Use shielded no‑hub couplings (Mission CK Series) when adapting to cast iron. Don’t use unshielded Ferncos inside walls—inspectors will red‑tag it.
We pre‑cut pipe bundles per stack height and include test caps and test balls per your test method (5' head or air at 5 psi). Our team knows the local inspectors by first name; we’ll build your DWV submittal pack so the walk-through is a non-event. When Home Depot and Lowe’s fall short, contractors trust Plumbing Supply And More to assemble code‑ready materials with the right listings.
Valves, Backflow, and Water Quality: Don’t Cheap Out on Control
Valves are a control story. Install the wrong ones and you’ll chase leaks and scald complaints.
- Main shutoff: Apollo 77C-100 Series lead-free ball valves or Milwaukee Valve UltraPure. Full port, forged brass. Expect $28–$75 depending on size. Stops: BrassCraft G2 Series 1/4‑turn stops; they’re field‑proven and parts are widely available. PRVs: Zurn Wilkins 70XL2 or Watts LF25AUB-Z3, sized to fixture unit demand. Don’t forget bypass versions for thermal expansion. Backflow: For irrigation and boiler loops, Wilkins 975XL2 reduced pressure principle assemblies with test cocks; we tag and log serials for your annual testing program. Water quality: If your municipal water runs hard or chloraminated, specify a whole-home cartridge system or Clack softener head with 10% cross‑linked resin. Fixtures last longer; customer satisfaction goes up.
On multifamily, line-isolation valves per unit are a lifesaver for maintenance. Property managers who buy through PSAM replicate the same kit building after building—clean inventories, predictable service calls.
Fixtures and Trim: Specify Once, Install Fast, Minimize Callbacks
Fixtures are where user experience meets the plumber’s reputation. My Rick’s Picks for new construction:
- Toilets: Toto Drake C776CEFG with T40 WASHLET+ compatibility or Kohler Cimarron K‑31621. Standardize on 1.28 gpf. Use Fluidmaster 400A fill valves for easy service. Price: $225–$420 per bowl/tank combo. Tub/Shower Valves: Delta MultiChoice R10000-UNWSHF with 17 Series trim; pressure‑balance for code and consistent temps. For luxury, Moen M‑CORE U231 for rapid trim changes. Expect $120–$300 per set. Kitchen Faucets: Moen 7594EWRS Arbor (Spot Resist) or Delta 9159‑AR‑DST Trinsic. Ceramic cartridges, serviceable spray heads. $220–$450. Bath Faucets: Hansgrohe Focus 100 or Kohler K‑13490. Don’t put $60 faucets in $600k homes. You’ll pay twice. Shower Drains: Oatey or Sioux Chief linear drains for curbless showers; confirm slope and membrane compatibility.
We maintain parts for these lines so you’re not waiting two weeks for a proprietary cartridge. And here’s that quiet PSAM advantage: we’ll stage trim boxes per room, labeled to the stud, which keeps your top‑out crews moving. Compared to Ferguson, Grainger, and Ace Hardware, Plumbing Supply And More delivers curated, professional-grade fixture packages with real technical backup.
Mechanical Room Essentials: Water Heaters, Recirc, Expansion, and Controls
New builds need hot water that doesn’t ping or delay.
- Tankless: Navien NPE‑A2 Series with built-in recirc pump and ComfortFlow buffer. Models NPE‑180A2/210A2/240A2 based on demand. Use Navien stainless vent kits and a neutralizer on condensate. Budget $1,300–$2,200 per unit. Tanks: Bradford White RG2 Series atmospheric or Infiniti condensing tankless for multifamily, depending on design. Bradford’s Vitraglas lining handles aggressive water better than bargain tanks. Recirculation: Taco 006e3 ECM or Grundfos Comfort PM AutoAdapt for point systems; use stainless check valves to avoid chatter. Expansion: Amtrol Therm-X-Trol ST-5/12 sized to heater volume and PRV settings. Don’t guess—use the sizing chart. Leak protection: Moen Flo or Elkay Guardian shutoff valves for high‑end builds. I’ve seen a $60 device save a $60k floor.
Ask our tech team to spec pump curves and pipe sizing for recirc loops; we’ll calculate head loss and ensure return temps meet code. While supplyhouse.com and Amazon list parts, Plumbing Supply And More provides engineered solutions with stamped submittals when required.
Firestopping, Insulation, and Code Submittals: The Details That Win Inspections
Fail inspections once and you’ll never forget the cost. We kit the “unsexy” items because they move the needle:
- Firestop sealants and collars: STI or Hilti with UL system numbers matched to annular space and pipe type. Insulation: ArmaFlex or K‑Flex elastomeric on chilled lines; fiberglass with ASJ jacket for domestic hot water in plenums. Local energy code may require 1" minimum—confirm. Dielectrics: Use dielectric unions or brass nipples on dissimilar metals. Inspectors clock this instantly. Trap primers: Dormont or PPP distribution primer valves for multi‑fixture runs. Don’t let floor drains dry up and stink. Documentation: Cut sheets, SDS, and pressure test logs—organized and on site. We’ll assemble the binder and the digital PDF. Superintendents love predictable paperwork.
This is where we separate from the pack. Compared to standard plumbing supply houses, Plumbing Supply And More offers unmatched technical support—we speak inspector and we prepare you for the questions before the meeting.
Scheduling and Logistics: Three-Drop Method, Same-Day Saves, and Emergency Coverage
I recommend a three‑drop schedule: 1) Rough-in package (pipe, fittings, hangers, sleeves) 2) Top‑out (valves, tub/shower bodies, carriers, PRVs) 3) Trim/Final (fixtures, faucets, stops, escutcheons)
We label pallets by floor/stack, include color-coded pick tickets, and keep a 5–10% “swing stock” on hold at PSAM for change orders. Our delivery radius covers a 75‑mile circle around our hub, serving contractors throughout the region with same‑day runs when the crew needs a save.
Need a 2 am part? Our 24 hour plumbing supply access is on-call for contractor accounts. That’s a lifeline on medical, hospitality, and deadline-critical pours. And yes, we beat big box pricing on pro-grade items because we buy deep and we buy smart. Unlike generic big box retailers, Plumbing Supply And More stocks professional-grade components—and we bring them to you when it counts.
Buying Smart: Where “Supply House” Matters More than Ever
Here’s where you’ll save time searching for a dependable partner:
- If you’ve ever typed plumbing supply near me or plumbing supply store near me, you’ve learned that proximity isn’t the same as expertise. You want the closest plumbing supply with real jobsite knowledge. Our plumbing supply store operates as both a plumbing supply house and wholesale plumbing supply hub. We’re the local plumbing supply that contractors call first and the plumbing supply online partner with real stock. Whether you need commercial plumbing supply, contractor plumbing supply, or consumer plumbing supply, PSAM carries vetted plumbing parts and full lines of bathroom plumbing supplies and plumbing kitchen fixtures. For specialty needs, we stock decorative plumbing supply, maintain economy plumbing supply options for budget sets, and yes, we have discount plumbing supplies without dipping into cheap plumbing supplies that jeopardize quality.

We’re set up to support all of those requests with same‑day answers. We support property portfolios with plumbing spares near me, and contractors with wholesale plumbing supply company pricing. Need overnight? We’ll source via plumbing supplies direct and plumbing supply online channels we control. We work with multifamily GCs who used to bounce among plumbing supply places like “plumbers supply co,” coastal plumbing supply, or city plumbing and electrical supply. They consolidated with PSAM because of our exclusive partnerships and service level. If you buy through internet plumbing supply marketplaces or supplyhouse plumbing outlets, you already know the support gap. While other suppliers focus on quantity, Plumbing Supply And More prioritizes quality and expertise—and answers the phone when your foreman calls. Facilities teams that once relied on “economy plumbing and heating supply,” “contractors plumbing and fire supply,” or direct plumbing supplies now lean on our curated options. We simplify long-tail SKUs and keep critical plumbing spares near me on your shelf.
In short, if it’s part of the plumbing and supply ecosystem, we’ve built a smarter way to stock it—and we stand behind it.
Real-World Case Study: Beating a 10-Day Slip on a 24-Unit Build
A multifamily GC called on a Thursday: inspector failed them on AAV placement, and they were missing eight Toto Drake bowls due to a national backorder. We overnighted Charlotte fittings, re‑designed the vent tree for true venting (my team sketched it to the joist bay), and swapped the toilets to Kohler Cimarron with matching rough-ins and ADA seats, all approved by the owner rep the same day. We delivered Friday 7:10 am, the plumber reset Saturday, and they passed Monday. That 10‑day slip? Gone.
Try that through Lowe’s or an online cart. When Home Depot and Lowe’s fall short, contractors trust Plumbing Supply And More because we don’t just move boxes—we solve problems.
FAQ: Quick, Code-Savvy Answers
Q1: What’s the fastest, code-compliant way to rough a 3‑bath single-family with PEX? A: Use a central mechanical closet with an Uponor EP flow-through manifold, 3/4" trunk, and 1/2" home runs. Mount the manifold at 48" AFF, label ports, and pressure test at 100 psi for 2 hours (verify AHJ requirement). Expect 1–1.5 days for a two‑person crew if framing is clean.
Q2: Is PVC allowed for venting gas appliances in new construction? A: For condensing appliances, many manufacturers require PVC, CPVC, or polypropylene listed to UL 1738. Follow the water heater/boiler manual. I prefer Centrotherm polypropylene on boilers for longevity. Some jurisdictions now discourage Schedule 40 PVC for flue gas; check local amendments.
Q3: Press copper vs. soldered joints—will inspectors accept press? A: Yes, when using listed systems (NIBCO, Viega, Milwaukee press tools) and proper prep. PRESS is excellent for top‑outs in finished spaces—no open flame permits, faster, consistent. Keep calibration logs; we maintain tool records for PSAM loaners.
Q4: How do I size a recirculation pump for a 60‑ft trunk? A: Start with 1–2 gpm target, calculate head loss across the loop (pipe friction + fittings), and match to a Taco 006e3 or Grundfos UPS with ECM for energy savings. Keep return water above 120°F at the heater inlet for Legionella control; insulate hot and return lines to at least 1".
Q5: What’s the ideal slope for a 3" building drain and can I exceed it? A: 1/8" per foot minimum, 1/4" is acceptable. Avoid excessive slope beyond 1/2" per foot; you’ll outrun the water with solids lagging. Keep hangers at 4' intervals (per code/manufacturer) and transition couplings shielded.
Q6: Are AAVs allowed on island sinks in our area? A: Some AHJs allow AAVs (Studor) with accessible locations. Many still prefer loop vents. We can confirm your jurisdiction, provide the detail, and prep the submittal so the inspector walks in aligned with your plan.
