Sprinkler Blowout & Winterization in Lehi
Licensed Lehi Plumbers. Commercial-Grade Compressors.
Every fall, Lehi City shuts down the pressurized irrigation system, and every spring we get calls from homeowners who skipped their sprinkler blowout and found cracked backflow preventers, split manifolds, and burst lateral lines when the water came back on. A professional sprinkler blowout in Lehi costs less than a single replacement valve and takes about 20 minutes. Water Damage Specialists winterizes sprinkler systems across Lehi with commercial-grade compressors, licensed plumbers, and the option to have the same crew shut off your stop and waste valve and inspect your indoor plumbing for freeze risk while they're there.

Why Sprinkler System Winterization Matters in Lehi
Lehi winter brings freezing temperatures that can leave water in your irrigation lines and cause frozen pipes that crack whatever holds them. The parts that fail most often are the ones that cost the most:
Backflow preventers and pressure vacuum breakers ($200 to $600+ to replace)
Manifolds and zone valves
Above-ground pipe near the stop and waste valve
Lateral lines that run shallow under sod
Sprinkler heads and nozzles that hold water
Utah homeowners are responsible for turning off pressurized irrigation connections in fall.
Draining the system by gravity isn't enough. Lehi yards are rarely graded to let every line drain, and low spots hold water no matter how long the drain valve stays open. A compressed-air blowout is the only reliable way to clear the system.
Lehi Pressurized Irrigation Shut Off
Most Lehi homes water their lawns from the city's pressurized irrigation (PI) system, which is the property's outdoor irrigation water supply and is separate from culinary water; in Lehi, that PI service is also commonly called secondary water. The city typically shuts the PI system down in mid-October and turns it back on in mid-April, though exact dates shift each year based on weather and reservoir levels. Check Lehi City's announcements for the current schedule.
Once the city shuts off PI, your system still has water sitting in every pipe. That water needs to come out before the first hard freeze, which in Lehi can come as early as late October. The safe window for a sprinkler blowout in Lehi is roughly the first week of October through early November, with the sweet spot right after the city shuts down the PI supply.
If your home is on a culinary-fed sprinkler system instead of PI, the same timing applies, but your stop and waste valve is what isolates the system.

Stop and Waste Valve Shut Off in Lehi
Most Utah sprinkler systems are isolated from the house supply by a stop and waste valve, a buried valve with a long key that both shuts off the water and drains the line downstream of it. Turning the stop and waste off and letting it drain is step one of winterization, and it's a step a surprising number of homeowners miss or do wrong.
Common stop and waste problems we see:
Valve stuck open from corrosion or debris, so the system never fully isolates
Valve turned off but not draining, leaving water above it to freeze
Key lost or valve box buried under landscaping
Valve installed too shallow and freezing itself
We locate your stop and waste, shut it off, confirm it's draining, and replace it if it's failed. A working stop and waste valve is what protects the pipe between the house and the backflow preventer, which is the most expensive section to repair.
Our Sprinkler Blow Out Service in Lehi
Here's what a Water Damage Specialists sprinkler blowout includes:
- Shut off the PI or culinary supply and the stop and waste valve.
- Open the drain valves and manual drains on the system.
- Connect a commercial tow-behind compressor to the blowout port, regulated to a safe pressure so we don't damage PVC or poly pipe or blow out heads; for PVC, that means staying at a maximum of 80 PSI, since excessive pressure can rupture lines and damage irrigation components.
- Blow out each zone individually until it runs dry, then repeat to catch residual water from the sprinklers.
- Set backflow preventer test cocks and ball valves to the half-open position so trapped water has room to expand.
- Put the controller in rain or off mode without wiping your programming.
- Note any leaks, broken heads, or valve issues we spot for spring repair.
Our technicians wear safety glasses during blowouts because debris can eject from fittings or heads.
We use full-size compressors, not portable shop units, because a compressor that can't deliver enough volume leaves water in the lines even when the heads look dry, and adequate CFM matters for clearing the system effectively.

Price depends on zone count and whether we're also servicing valves. For comparison, a cracked backflow preventer alone runs $300 to $700 to replace, and a split line under sod means digging up the lawn in April. Compared with a new system, which typically costs $4,000 to $7,500 to install, paying for a blowout is a simple way to protect your setup and save money, especially since Lehi uses pressurized irrigation that can reduce installation costs. The blowout pays for itself the first time it prevents a freeze break.
