How to Winterize Your Outdoor Plumbing in Arvada, CO
Arvada’s first hard freeze typically arrives in October, sometimes earlier. Outdoor faucets, hose bibs, sprinkler systems, and any exposed plumbing left unprotected can freeze and split within the first cold snap. The repair costs far more than the prevention. Arvada Plumbing Pros offers fall winterization service for homes and irrigation systems across Arvada. Call (720) 787-0333 to schedule before the first freeze.
Why Winterization Matters in Arvada
Water expands by about 9 percent when it freezes. A garden hose left attached to an outdoor faucet traps water in the faucet body and the section of pipe just inside the wall. When that trapped water freezes, the expansion has nowhere to go, and it cracks the faucet body or the pipe behind it, often inside the wall where you cannot see it.
The damage does not show up until spring, when you turn the faucet on and water sprays from a crack inside the wall, soaking insulation and framing all winter without anyone noticing. By the time the leak is discovered, the water damage has been accumulating for months. A burst pipe repair for an outdoor faucet that froze in November and was not discovered until March involves both the pipe repair and remediation of months of hidden water damage.
Sprinkler systems face the same risk at a larger scale. Irrigation lines run shallow, often just below the frost line or shallower in spots, and hold water in every zone, valve, and the backflow preventer after the last watering of the season. An unblown sprinkler system in Arvada commonly has cracked pipes, split valves, and a damaged backflow preventer by spring, none of which are visible until the system is turned on and water sprays from multiple points.
Winterizing Outdoor Faucets and Hose Bibs
Disconnect every garden hose from every outdoor faucet before the first freeze. A hose left attached traps water in the faucet, even on faucets marketed as freeze-resistant or “frost-free,” and defeats the freeze protection those faucets are designed to provide.
Most Arvada homes have a dedicated shutoff valve for each outdoor faucet, located inside the home near where the pipe passes through the wall, typically in a basement or crawl space. Shut this valve off completely. This is the step most homeowners skip, and it is the step that actually prevents freeze damage on faucets without built-in frost protection.
With the interior valve closed, open the outdoor faucet to drain any water remaining in the pipe between the valve and the faucet. Leave the outdoor faucet in the open position for the winter. This relieves any pressure from water that might still seep in, giving it room to expand without cracking the pipe.
Foam faucet covers, available at any hardware store, add an extra layer of protection for faucets on north-facing walls or in particularly exposed locations. This is a supplement to shutting off the interior valve, not a replacement for it. A foam cover alone does not protect a faucet with the interior valve left open and water still in the line.
Winterizing Sprinkler and Irrigation Systems
Sprinkler winterization in Colorado requires blowing out the lines with compressed air, a process most homeowners hire a professional for because it requires an air compressor with sufficient CFM output and the knowledge to do it without damaging the irrigation components.
- Shut off the water supply to the irrigation system at the main valve, separate from the household water supply
- Connect a compressed air source (typically 50 to 80 CFM for residential systems) to the system at the connection point closest to the water source
- Open zone valves one at a time, starting with the zone furthest from the air source, and blow out each zone until no more water is expelled from the sprinkler heads
- Drain and protect the backflow preventer, which is the most expensive single component and the most commonly damaged part of an unwinterized system
- Insulate any above-ground exposed piping, valves, and the backflow preventer assembly with foam pipe insulation or an insulated cover
Using too much air pressure or the wrong CFM for your system size can damage valve diaphragms and sprinkler head seals, turning a preventive service into a repair job. This is the part of winterization most worth hiring out. We coordinate sprinkler blowouts with general winterization visits across Arvada.
Other Areas to Check Before Winter
Beyond faucets and sprinklers, a complete fall winterization in Arvada covers a few additional areas that are easy to overlook:
- Pipes in unheated spaces: crawl spaces, garages, and attics with exposed supply pipes should be checked for adequate insulation before temperatures drop. Pipe insulation sleeves are inexpensive and effective for pipes that run through these areas.
- Water heater: a water heater inspection before winter catches any developing issues before the heater is under maximum demand during the coldest months. Cold incoming water in winter makes a marginal water heater work harder.
- Sump pump: if your home has a sump pump, test it before winter. A sump pump that fails during a winter thaw or ice dam event can result in basement flooding when temperatures are too low for typical remediation timelines.
- Known vulnerable pipe locations: any pipe that has frozen in a previous winter is likely to freeze again in the same spot unless the underlying cause (lack of insulation, exposure to cold air infiltration) is addressed. A plumbing inspection can identify these locations before they become emergencies again.
