You’ll need an air compressor with a regulator, the right blowout adapter, a quality air hose, basic hand tools, and insulation supplies. Add safety gear—eye and ear protection—and a few extras like Teflon tape and rags. Optional: foam covers for the backflow and hose bibs. That’s the short list to winterize a sprinkler system. What you’ll learn from this blog The essential tools and materials (and the ones you can skip) What PSI and CFM you actually need to blow out sprinkler lines Which fittings and adapters connect your compressor [...]

To winterize your lawn sprinkler system, shut off water, drain or blow out lines with compressed air, open test cocks, protect backflow preventer, set controller to winter mode, and insulate exposed parts. Doing this before first hard freeze prevents burst pipes, cracked valves, and costly repairs. Most homeowners can complete it in under an hour.

To check for leaks after winterization, restore water slowly, watch your meter’s leak indicator, then test each sprinkler zone for hissing, soggy spots, or low pressure. Inspect the backflow preventer and valve boxes for drips or bubbles (use soapy water). Compare before/after meter readings. If the meter moves with everything off, you’ve got a leak.

Yes—if you expect freezing temps or you’re shutting down your sprinkler system, you should drain backflow preventer assemblies. Draining prevents burst brass, costly leaks, and possible contamination. In warm weather and normal operation, don’t drain; keep them pressurized and tested annually. Local codes matter, too, so follow manufacturer guidance or hire a pro.

Short answer: no—antifreeze isn’t safe for your lawn. Most automotive antifreeze (ethylene glycol) is toxic to grass, soil life, pets, and wildlife, even in small amounts. If you spill it, act fast: contain, absorb, and dispose properly. There are safer options for winterizing plumbing, but none belong on turf. We’ll show what to use instead and how to handle leaks.

Yes—over-blowing a sprinkler system can crack PVC, pop fittings, shred seals, and ruin backflow preventers. The fix is simple: prioritize volume over pressure and regulate air. For most homes, keep blowout pressure around 40–60 PSI, never above 80 PSI, and pulse each zone until mist fades. That’s winterization without damage.
