Winterization FAQs
When should I winterize my sprinkler system in Chester County?
In Chester County, sprinkler winterization should be completed before consistent freezing temperatures — typically mid-October through mid-November. JHL recommends scheduling in September or early October to secure your preferred date before the peak season rush.
What happens if I do not winterize my irrigation system?
Unprotected irrigation systems can suffer frozen and cracked pipes, burst valves, cracked backflow preventers, and failed heads. Repairs from freeze damage typically cost $500–$3,000+, far exceeding the cost of a proper blowout.
Can I winterize my own sprinkler system in Chester County?
DIY winterization is possible but risky without commercial-grade compressed air. Household compressors rarely generate enough CFM to fully clear all zones. Incomplete blowouts leave water in lines that freezes and causes the exact damage you're trying to prevent. Professional blowout is the safest approach.
What does JHL's winterization service include?
JHL's winterization includes: compressed air blowout of every zone, backflow preventer shutdown, controller shutdown and frost mode programming, valve inspection during blowout, and a written system status report after service.
How early should I book my sprinkler blowout in Chester County?
September is ideal. October is still fine but slots fill quickly. By late October, JHL's schedule is typically full for the season. Booking early also ensures you get the service before unexpected early cold snaps.
