I’m Rick Callahan—Master Plumber, 25+ years on job sites and in mechanical rooms, and Product Expert at Plumbing Supply And More. When the first frost hits, the calls start: burst hose bibbs, split copper in crawl spaces, and boiler relief valves popping off after a cold snap. Most of it’s preventable with the right materials and a disciplined checklist. Consider this your field-tested playbook for winterizing—with the exact supplies I spec for contractors and serious DIYers alike.
Before we dive in, a quick note: you don’t winterize with wishful thinking or bargain-bin parts. You do it with proven gear, clean installs, and a sharp eye on your local code. That’s where we come in. Unlike generic big box retailers, Plumbing Supply And More stocks professional-grade components, and our counter team actually installs the products we sell. If you’re searching for a plumbing supply near me or a closest plumbing supply with real knowledge, you’ve found it.
Why Winterizing Matters: Real Failures, Real Fixes
Every January, I get called to a two-story with a ceiling pimple ready to burst. Homeowner left the hose connected, froze the sillcock, and the pipe split in the wall. Insurance covered the drywall—didn’t cover the two-week hotel stay.
Freeze damage happens when standing water expands to ice. Outdoors, it’s hose bibbs and irrigation lines. Indoors, it’s poorly insulated rim joists, crawl spaces, garages, and apartments with unbalanced heating zones. Then there’s boiler and water heater scenarios—condensate traps freezing, PRVs chattering from pressure swings, and mixing valve issues causing lukewarm showers.
The fix isn’t just turning valves. It’s product choice plus installation detail: anti-siphon frost-free sillcocks with proper pitch, insulated pipe runs, heat trace on vulnerable lines, properly set expansion tanks, and pressure-reducing valves tuned for winter pressure spikes. At Plumbing Supply And More, we’ve built kits for each scenario so pros and homeowners can winterize without guesswork.
While other suppliers focus on quantity, Plumbing Supply And More prioritizes quality and expertise—and we’ll walk you through the install step-by-step.
Exterior Protection: Hose Bibbs, Shutoffs, and Insulation That Works
Start outdoors. Remove hoses, drain hose bibbs, and upgrade to frost-free.
- Frost-Free Sillcocks: I recommend Woodford Model 22 (anti-siphon, vacuum breaker), or Prier P-164. Both meet ASSE 1019/UPC and are code-safe. We stock sizes 4–14 inches to match wall thickness. Expect $45–$120 depending on length and finish. Install takes 30–75 minutes if you can access the interior. Interior Shutoff with Drain: If you’re not replacing the sillcock, add an interior ball valve with a drain cap—Apollo 77-100 or Webstone 40612W. Drain the line, then leave the faucet open at a slight drip during deep freeze if the line still runs through cold space. Insulated Hose Bibb Covers: Cheap insurance—$6–$15. They don’t replace frost-free valves but they help. Pipe Insulation: Use Armaflex or K-FLEX 1/2"–1" wall thickness for exterior walls and unconditioned spaces. Tape seams—don’t rely on friction fit.
Pro tip: Frost-free sillcocks only work if the exterior end is pitched downward and the interior section is inside the warm envelope. If the stem sits in a cold garage wall, you still need insulation and air sealing.
If you’re scouting a plumbing supply store near me that keeps Woodford and Prier on the shelf in all lengths, we’ve got them—because when the freeze is coming, lead times aren’t an option. When Home Depot and Lowe’s fall short, contractors trust Plumbing Supply And More for stock and advice that hold up under pressure.
Interior Lines: Insulate, Heat Trace, and Air Seal the Weak Spots
Most freeze-ups happen in three places: over garages, at rim joists, and in ventilated crawl spaces. My rule: if you feel a draft, the water feels an ice bath.
- Closed-Cell Pipe Insulation: 1/2" wall for mild climates, 3/4"–1" wall for harsh winters. Don’t forget elbows and tees—use pre-formed fittings or miter and tape properly. Heat Cable: Raychem FrostGuard or nVent RAYCHEM HWAT with integral thermostat. Use on PEX, copper, or CPVC as specified—follow the brand’s listing. You’ll pay $4–$10 per foot. It’s cheap compared to a repair call. Air Sealing: Spray foam around pipe penetrations, sill plates, and b-vents passing through conditioned-to-unconditioned transitions. This is drastically underrated. Smart Monitoring: Consider leak sensors (Flo by Moen, Honeywell Resideo Lyric) at low spots. Early alerts save walls.
We carry these in our plumbing supply house and our plumbing supply shop because winter is not when you want to wait on a shipment. Need it tonight? We’ve got a 24 hour plumbing supply line for our contractor accounts during cold events—ask our counter team for details.
Water Heaters and Expansion Control: Prevent Pressure Surges and Lukewarm Water
Winter brings colder inlet water, which raises water heater recovery demand and increases expansion events. Here’s what fails: weak anode rods, undersized or failed thermal expansion tanks, and old PRVs not regulating properly.

- Thermal Expansion Tanks: Amtrol ST-5 or Watts DET-5 for typical residential. Set the air charge to match house static pressure—usually 50–60 psi. Expect $60–$120. Replace every 5–7 years or if waterlogged. Pressure-Reducing Valve (PRV): Cash Acme EB-45 or Watts LF25AUB-Z3. If your static pressure is above 75 psi, reduce to 55–65 psi. Frozen pipes love high pressure swings—don’t give them ammo. Mixing Valves: If you’re seeing fluctuating temps, upgrade to a thermostatic mixing valve like the Honeywell AM-1 or Caleffi 521. For recirc systems, check the pump timer and aquastat to prevent cold slugs. Anodes and Flush: Replace aluminum anodes with magnesium or powered anodes in hard water zones. Flush sediment—cold inlet temps stir up the tank.
We stock spec sheets and cut sheets at the counter and online for quick submittals. Compared to standard plumbing supply houses, Plumbing Supply And More offers unmatched technical support, including real-world sizing help for multi-unit properties and light commercial.
Boilers, Hydronics, and Freeze Protection: Keep Heat Moving
If you have hydronic baseboard or radiant heat, freezing is catastrophic. A few checks go a long way:
- Glycol: Use a propylene glycol blend like Hercules Cryo-Tek 100 or Sentinel X500 for closed-loop systems. Maintain 30%–40% concentration depending on climate. We test glycol on site—drop by the local plumbing supply counter with a sample. Backflow and Fill Valve: Check your Watts 9D backflow and Bell & Gossett SA fill valve. If they’re old, rebuild kits are cheap insurance. Air Elimination: Spirovent microbubble eliminators keep your loops moving. Air locks are a freeze risk in baseboards along exterior walls. Pump Health: Grundfos UPS 15-58F or Taco 007e ECM circulators are reliable. ECM saves energy during long winter cycles.
Serving contractors throughout our region, we keep hydronic parts in our commercial plumbing supply and wholesale plumbing supply areas year-round, because cold snaps don’t wait three days for a “warehouse transfer.”
Irrigation, Garages, and Outbuildings: Smart Draining and Heat Choices
Sprinklers and garages generate the most after-hours calls. Do it right:

- Irrigation: Blow out zones with a compressor to 50–80 psi (respect the manufacturer’s limits). Use an RPZ or PVB backflow (Watts 009M2 for RPZ, Watts 800M4 for PVB) and winterize per ASSE guidelines. Don’t forget to open test cocks. Garage/Workshop: If plumbing must run in unconditioned space, combine insulation with heat trace and install a low-temp thermostat to kick on a 240V unit heater. Set to 40–45°F. Outbuildings: If seasonal, fully drain and add RV antifreeze to traps. If year-round, insulate and use self-regulating heat cable properly bonded and grounded.
We stock the fittings, pressure gauges, and blow-out adapters you won’t find at a typical consumer plumbing supply aisle. Unlike generic big box retailers, Plumbing Supply And More stocks professional-grade components that meet code and stand up to service.
Drainage, Traps, and Vacant Properties: Freeze Doesn’t Care Who’s Home
Vacant or part-time residences are high risk. Here’s how I set them up:
- Drain and isolate hose bibbs, irrigation, and any seasonal fixtures. Pour RV antifreeze into floor drains, shower traps, and sump pits to prevent trap evaporation and freezing—two cups per trap generally does it. Set the thermostat no lower than 55°F; keep interior doors open to move air. If power is unreliable, consider battery-backed leak alarms and heat sensors.
We help property managers build repeatable checklists and bulk up on the right plumbing parts. Ask about our contractor accounts and bulk pricing—we’re a wholesale plumbing supply company with logistics that save time and miles.
Supply Lists by Scenario: What I Actually Load on the Truck
When I prep for winterization jobs, here’s a lean kit that gets it done:
- Exterior freeze-up prevention Woodford 22 or Prier P-164 frost-free valves (6–10” typical) Apollo/Webstone 1/2"–3/4" ball valves with drain Hose bibb covers, Armaflex 1/2"–1" insulation, tape Interior pipe protection nVent RAYCHEM heat cable with end seals Fire-block foam, silicone, EPDM pipe boots for air sealing Water heater/pressure control Amtrol ST-5 expansion tank, Watts LF25AUB-Z3 PRV Watts 3/4" relief valve, magnesium anode rod Hydronics Cryo-Tek glycol, Spirovent, Taco 007e RPZ/PVB parts, test cocks, pressure gauges

Choosing Pro-Grade Over Commodity: Where Quality Actually Saves Money
Let’s hvac supply house talk numbers. A frost-free sillcock from a discount aisle might be $29; a Woodford 22 is $65–$95. The cheap valve splits or the vacuum breaker fails, and your repair bill plus drywall is four figures. That’s false economy.
- Valves and Fittings: Lead-free, low-zinc brass holds threads and resists dezincification. Brands like Webstone, Apollo, and Viega ProPress are worth it. Heat Cable: Self-regulating cable draws only what it needs, so it’s safer and cheaper over time vs. constant wattage tape. Insulation: 1" wall insulation reduces freeze risk dramatically compared to 3/8". The cost difference is minimal; the protection isn’t.
We carry premium lines through exclusive partnerships that many competitors can’t access. While other suppliers focus on quantity, Plumbing Supply And More prioritizes quality and expertise—and yes, our pricing beats the big boxes regularly.
