Your First Visit to a Supply House: A Beginner’s Checklist
Walking into a supply house for the first time can feel like stepping onto a runway with a jet warming up—lots of motion, lots of terminology, and zero patience for guesswork. I’m Rick Callahan, owner of Plumbing Supply And More, and I’ve spent more than three decades behind the counter, on the jobsite, and in the warehouse. I’ve helped first-time homeowners, seasoned contractors, and property managers alike get exactly what they need—fast. If you’ve searched “ plumbing supply near me” or “ plumbing supply store near me,” you’re already halfway there. This guide will get you the rest of the way so your first visit to a plumbing supply house feels productive, not overwhelming.
And yes—the title that brought you here, Your First Visit to a Supply House: A Beginner’s Checklist, is your roadmap. Keep it handy, and you’ll walk out with the right materials, fair pricing, and the confidence to install with no surprises.
Know Before You Go: What to Bring and How to Ask
Your trip starts before you hit the door. Bring photos of the space, measurements, and any existing components you’re replacing. I’m talking model numbers, valve stem length, pipe sizes, and fixture brand. If you’re unsure of a thread type? Bring the old fitting. I’ve matched mystery faucet cartridges and vintage flush valves because a customer brought the broken part in a sandwich bag—beats guessing every time.
Measure pipe outer diameters: 1/2", 3/4", 1", etc. For copper, that’s nominal size. For PEX, nominal = OD for most systems (e.g., 1/2" PEX is roughly 5/8" OD). Photograph shutoff valves, trap arms, and water heater labels—especially the data plate with BTUs, gallon size, and recovery rate. Write down appliance models: AO Smith G6-50YBRT, Bradford White RG240S6N, Navien NPE-240A2, Rheem RTGH-95DVLN.
Pro tip: If you’re planning PEX, list your manifold layout and zones. We’ll spec crimp, clamp, or expansion (Uponor/Wirsbo) fittings based on your tool kit.
Bold truth: Unlike generic big box retailers, Plumbing Supply And More stocks professional-grade components that match your job’s specs the first time, saving you returns and rework. Where others push “one-size-fits-none,” we confirm compatibility on the spot.
Decoding the Counter: How a Supply House Really Works
At a real plumber supply house, there’s a counter team, a will-call shelf, and often a yard or backstock area. You’ll hear order numbers, job tickets, and “pick slips.” Don’t sweat it—just tell us the job: “Replacing a 40-gallon gas water heater in a basement with a 3" B-vent and 1/2" CSST feed.” We’ll translate that into SKUs: heaters, vent connectors, dielectric hvac supply house unions, pan, expansion tank, gas shutoff, sediment trap, and code-required T&P discharge.
Insider secret: Ask for spec sheets and submittals—especially for inspection. For example, installing a PRV? We’ll print the Zurn Wilkins 70XL spec with pressure ratings and NSF listings. Replacing a toilet? Ask for rough-in templates for Toto Drake CST776CEG or Kohler Cimarron K-4369 to avoid baseboard and shutoff interference.
And if you’re after HVAC gear alongside plumbing—say, thermostat wire or a condensate pump—ask. We’re also your hvac supply house and refrigeration supply house for jobsite convenience: think DiversiTech CP-22 pumps, RectorSeal Safe-T-Switches, and Supco hard start kits.

Pipe, Fittings, and the PEX Question: Choose the Right System
Copper, PEX, CPVC, PVC—each has a place. If you’ve googled “ pex supply house” or “ pvc supply house,” you’re already thinking smart. Here’s the real-world rundown:
Copper (Type L for domestic): Best for durability and high heat; typical costs run $3–$5/ft for 1/2" Type L in today’s market. Solder with lead-free solder and water-soluble flux. Don’t flux the whole joint—flux only the socket. PEX: Fast, flexible, and freeze-tolerant. Three systems: Crimp (copper rings): economical; use a Go/No-Go gauge. Try Nibco and Sioux Chief fittings. Clamp (stainless pinch): more forgiving; Milwaukee M12 clamp tool is a workhorse. Expansion (Uponor): best flow; needs the Uponor ProPEX tool; fittings like EP or brass; model A7040025 rings. CPVC: Code-approved, but be strict on solvent types and cure times. Great for commercial hot water risers when copper is cost-prohibitive. PVC/ABS: Drainage and venting only in most jurisdictions; schedule 40 for standard residential DWV; purple primer is required in many municipalities.
On potable lines, use full-port ball valves—Apollo 77F or Webstone Pro-Pal—with drain ports for serviceability. Building steam heat? Different animal—talk to our heating plumbing supply near me team about vents and low-pressure code.
Why it matters: Compared to standard plumbing supply houses, Plumbing Supply And More offers unmatched technical support—we’ll match your tool ecosystem, verify code requirements, and prevent mistakes like mixing F1960 expansion rings with crimp fittings.
Fixtures, Trim, and “Looks vs. Lasting”: Brand and Model Picks That Don’t Bite Back
You want your shower to look sharp and work flawlessly. That happens when the rough-in and trim talk to each other. I’ve seen too many folks buy an eye-catching trim kit without the correct valve body. Not here.
Shower valves: Delta MultiChoice R10000-UNBX pairs with 13/14, 17, or 17T trims; Moen Posi-Temp 62300 and Moen U by Moen for smart controls; Kohler Rite-Temp K-304-KS. Pro tip: Pressure-balance is standard; thermostatic (Delta 17T, Kohler K-2971-KS) gives you stable temps in multi-bath homes. Toilets: Toto Drake CST776CEG (CEFIONTECT glaze, 1.28 GPF) is a champ; American Standard Cadet Pro is a solid budget pick; Kohler Santa Rosa if you need a compact elongated bowl. Faucets: Chicago Faucets 895-ABCP for commercial heavy-use; for residential kitchens, Delta 9113T-DST Touch2O holds up and parts are available. Water heaters: AO Smith, Bradford White, Rheem—pick based on venting, recovery, and serviceability. For tankless, Navien NPE-240A2 with 2" intake/3" exhaust; add a scale inhibitor for longevity.
If you’re after finishes that last, ask us about PVD coatings and ceramic disc cartridge availability. For high-traffic rentals, I’ll guide you to skus with easy-replace stems you can stock in your plumbing parts bin.
Straight talk: While other suppliers focus on quantity, Plumbing Supply And More prioritizes quality and expertise—we’ll stop you mid-aisle if the trim doesn’t match the rough-in, and we’ll set you up with rough protection plates so your tile guy doesn’t nick your valve body.
Code, Permits, and Inspectors: Pass the First Time
In our area, professional plumbers choose vendors who know local code as well as the inspector. That’s us. Whether you’re under IPC, UPC, or a local amendment, we’ll guide you: air gap on dishwashers, vacuum breakers on hose bibbs, expansion tanks with PRVs, and anti-scald protection on showers.
Examples:
Thermal expansion: If you have a closed system (check valve or PRV), most jurisdictions require an expansion tank (e.g., Watts DET-5 for 40-gallon). We’ll size it by incoming pressure and water heater setpoint. Sump/effluent: Use a check valve with a union above the pump for service. Zoeller M53 “Mighty-Mate” is the classic; liberty 257 is great too. Dielectric unions on water heater connections with dissimilar metals. Gas code: sediment trap (drip leg) required at appliance; we stock Ward malleable fittings and Dormont flexible connectors with proper BTU ratings.
Bring your permit notes. We’ll print submittals for your inspection packet and explain “Your First Visit to a Supply House: A Beginner’s Checklist” in code terms—what the inspector expects to see taped to the heater, tagged on the PRV, or labeled on the condensate pump.
Pricing, Accounts, and How to Save Without Cutting Corners
There’s a myth that supply houses are pricier than big box stores. Not for pro-grade gear, and definitely not with the right account setup. We offer contractor accounts, project pricing, and bulk discounts that beat retail—especially on copper, valves, and rough-in packs.
Typical savings: 10–25% on staple rough materials when you set up a contractor account or property program. Stock vs. special order: We carry a deep on-hand inventory; special orders are clearly quoted with lead times and alternatives. Ask about promos: Yes, we do monthly bundles and occasional supply house coupon, supply house coupon codes, and a supply house discount code for seasonal stock—if you’re a newsletter subscriber. We’ll also honor a reasonable supply house promo code for first-time pro accounts.
And I’ll say the quiet part out loud: When Home Depot and Lowe’s fall short, contractors trust Plumbing Supply And More. Why? Because you’ll get the exact valve trim depth spacer, the right o-ring kit, and the expansion tank support strap—not “whatever’s on Aisle 17.”
Navigating Specialty Departments: Electrical, HVAC, and Refrigeration Essentials
Many jobs blur lines: a water heater needs venting and bonding; a condensate line needs a pump and overflow safety. At our supply house electrical counter, we’ll set you up with bonding clamps, #6 copper for water service bonding, thermostat wire (18/5), and proper strain reliefs. Need an ac supply house item? We stock Yellow Jacket charging hoses, Supco hard start kits, RectorSeal coil cleaner, and DiversiTech pads.
For air conditioner supply house needs: condensate switches, line set covers (SpeediChannel), and UV lights for coil sanitation. On the refrigeration supply house side: flaring tools, nitrogen regulators for brazing, and ball valves rated for refrigerant. We’re not trying to be all things to all people; we’re ensuring the job gets completed end-to-end with safe, code-compliant materials.
Here’s the difference: Unlike generic big box retailers, Plumbing Supply And More stocks professional-grade components like Honeywell Resideo 1" water heater gas controls, A.O. Smith anode rods by model, and RectorSeal Safe-T-Switch SS1 for primary condensate pans—items that save callbacks.
Parts That Save the Day: The “Oh No” Shelf You’ll Be Glad We Have
Every veteran knows the small parts wall is where projects live or die. We maintain deep stock in:
Cartridge kits: Moen 1222/1225, Delta RP46074, Kohler GP800820. Toilet internals: Fluidmaster 400A fill valves, Korky 528MP, Toto THU500. Repair clamps: Smith-Blair 261 for quick copper pinhole fixes. Specialty washers, packing, and bonnet nuts for legacy fixtures. Gas and water heater service kits: thermocouples, igniters, and pilot assemblies.
And because homeowners ask: yes, we have genuinely durable bathroom plumbing supplies—wax rings with flange reinforcement, solid brass P-traps for exposed installations, and metal pop-up assemblies that won’t crumble after a year.
If you’re browsing plumbing supply online, we sync our inventory so you can check stock before you drive. Prefer local? We’re your local plumbing supply with same-day pickup and delivery within a 50-mile radius for account holders—serving contractors throughout the region with emergency supply runs when you’re in a bind.

Same-day delivery and 24/7 emergency access for account customers—yes, we’re your 24 hour plumbing supply when the boiler cracks Friday at 6 PM. Warranty guidance: We help process manufacturer claims and match equivalent replacements when models update. Technical support: Pump curves, pipe sizing, fixture scheduling, and venting diagrams. We’ll sketch a simple isometric if that’s what gets you through inspection.
Bottom line: Compared to standard plumbing supply houses, Plumbing Supply And More offers unmatched technical support—from product selection to install tips to code paperwork, all under one roof.

Local Expertise: Codes, Climate, and Real-World Install Tips
Our area’s winter freeze-thaw cycles and water chemistry dictate smart choices. PEX runs in exterior walls? Insulate thoroughly and avoid horizontal attic spans unless protected and heat-traced. High chloramine levels? Choose cartridges and gaskets that tolerate it, and consider whole-home filtration: Pentair PRF systems or Watts OneFlow for scale reduction.
Local inspectors here want:
T&P discharge within 6" of floor or to an approved receptor, full-size, gravity, no threads at end. Vacuum relief on top-fed heaters where required. PRV when static pressure exceeds 80 PSI—Watts 25AUB with gauge on a hose bibb to verify. Cleanouts at base of stacks and at every change of direction >135°.
We’ve built supplier relationships that matter: Uponor, Viega, Watts, Webstone, Delta, Toto, Navien, Zoeller, Liberty, and more. That’s why pros searching for contractor plumbing supply, commercial plumbing supply, or wholesale plumbing supply call us first—and why homeowners looking for the best plumbing supply experience become customers for life.
And for those wondering about competitors: When Home Depot, Lowe’s, Ferguson, or Grainger can’t source the exact spec you need, Plumbing Supply And More delivers with premium inventory and same-day solutions. We don’t just “have something like it”—we have the right thing.

FAQ: Your First Visit to a Supply House—Answered
How do I know if I need copper, PEX, or CPVC for my job?
Ask about temperature, pressure, and exposure. Copper Type L is excellent for durability and high-heat areas; PEX (crimp, clamp, or expansion) is ideal for speedy retrofits and freeze resistance; CPVC works for hot water lines with correct solvent cement and cure times. Our team will confirm local code acceptance and help you choose tools and fittings that match. If you’re unsure, bring a piece of your existing line and photos—we’ll identify it at the counter.
Can I get contractor pricing if I’m a serious DIYer or property manager?
We offer property and volume accounts with tiered discounts based on annual spend and product categories. That means reliable pricing on staples and project quotes on larger buys. Ask about bulk pricing on valves, copper, and PEX coils. We also run periodic specials and a supply house discount code for first orders on select categories.
What brands and model numbers do you recommend for dependable fixtures?
For showers: Delta R10000-UNBX with 17T trims; for toilets: Toto Drake CST776CEG or Kohler Cimarron; for water heaters: AO Smith or Bradford White tanks sized to demand; for sump: Zoeller M53. For PEX expansion, Uponor with F1960 rings; for crimp/clamp, Sioux Chief or Nibco brass. We’ll provide spec sheets so you can pass inspection and order parts easily down the road.
Do you deliver and how fast?
Yes. Same-day delivery is available within roughly 50 miles for account holders, with emergency options after hours. Need three water heaters and a pallet of copper by 2 PM? We make it happen. This is why local contractors say we’re the closest plumbing supply that actually solves problems, not just moves boxes.
Can you help me comply with local codes and inspections?
Absolutely. We’ll size expansion tanks, confirm PRV requirements, provide approved venting components, and print submittals. If your municipality requires specific vacuum breakers or air gaps, we’ll match what the inspector wants. Our counter crew is your shortcut through red tape.
