Why Highland Park requires an irrigation backflow test
Sprinkler heads sit in soil, fertilizer, and pet waste. If pressure in the Highland Park main drops — a hydrant flush, a water main break — water can be siphoned backward out of your yard and into the drinking water system. The backflow assembly on your irrigation line prevents that, and Town of Highland Park Public Works requires proof each year that it still works.
Where your assembly is and what we do
Most Highland Park homes have a double check or pressure vacuum breaker assembly near the water meter, in a green in-ground box, or above ground close to the house. Our technician isolates it, tests each check with calibrated gauges, notes the results, and restores the system. You do not have to be home — just leave the gate unlocked or send a gate code. On-site time is typically 20 to 30 minutes.
Freeze damage and failed assemblies in Highland Park
The most common failure we see in Highland Park is a cracked bonnet or split body from a hard freeze, followed by debris fouling a check. We carry common irrigation parts, so a failed test often becomes a same-visit repair and re-test. Once it passes, we submit the report to Town of Highland Park Public Works and you are done for another year.
What irrigation backflow testing looks like in Highland Park
Highland Park irrigation systems are large, old, and heavily zoned, often with a dedicated assembly for the front landscape and another for the back. Failures tend to be worn first-check rubber and fouled relief valves from years of grit, not freeze damage, because most of these devices sit in protected, landscaped enclosures. We bring legacy rebuild kits on every Highland Park route.
