Based in Rosemead, on the road across eight counties. Local enough for a same-day emergency, equipped to handle compliance work anywhere in the region.
Backflow testing and certification, cross-connection surveys, fire service assemblies, and commercial plumbing across the whole of Southern California.
That's the whole of Southern California — if
you're in the region, we serve you.
No city is off the list. Call and tell us where
the job is.
This is home. Emergency calls, drain work, water heaters, and anything where you need someone at the door quickly.
These are the closest to our shop, so they get the fastest slots — not a limit on where we go.
Work that's planned rather than urgent, we'll travel for — across all eight counties.
Southern California isn't one water system — it's hundreds of purveyors, each with its own notice format, submission process, deadline schedule, and paperwork quirks. A tester who only ever works one city learns one set of rules.
Covering eight counties since 1978 means we've filed with a lot of them. If your district has an unusual form or an online portal that never works, chances are we've dealt with it before.
Tell us where the job is and we'll tell you when we can be there.
