What We Do

Full-Service Plumbing, Plus the Specialty Work

Most plumbers can clear a drain. Far fewer are certified to test and certify backflow prevention assemblies — we do both, across all of Southern California, which means one call instead of two.

Backflow Testing & Certification

Annual testing, certification paperwork filed with your water purveyor, plus repair and replacement of failed assemblies. Residential, commercial, and irrigation systems.

Our Specialty

Got a Backflow Notice in the Mail?

If your water district sent you a letter, you're on a clock. California requires annual testing of backflow prevention assemblies by a certified tester, and the report has to be filed with your water purveyor — not just handed to you.

We handle the whole thing: test the assembly, repair it if it fails, and file the paperwork so you're compliant before the deadline. If you manage multiple properties, we'll put them all on one schedule.

How It Works

No Surprises, Start to Finish

The part most people dread about calling a plumber is not knowing what it'll cost or when anyone will actually show up. We fixed both.

Request Service

Call or Send a Request

Tell us what's happening. For emergencies we'll talk you through shutting off the water while we're on the way.

We Diagnose On Site

We find the actual cause — not the easiest thing to replace — and explain what we found in plain language.

You Approve the Price

Upfront pricing before any work starts. No hourly meter running while you decide.

We Fix It and Clean Up

Done right the first time, site left clean, and we stand behind the work.

Common Questions

Questions We Get a Lot

How often does a backflow device need testing?

In California, backflow prevention assemblies generally must be tested at least once a year by a certified tester, and the results submitted to your water purveyor. Some districts require more frequent testing for higher-hazard properties. If you received a notice, it will state your deadline — send us a photo of it and we'll tell you exactly what's needed.

Do you charge for estimates?

We give you a firm price before any work begins, so you know what you're agreeing to. Call us with the details and we'll walk you through how pricing works for your specific job.

Are you available for emergencies at night or on weekends?

Yes. Burst pipes and sewer backups don't wait for business hours. Call (626) 281-6736 any time — if it's an emergency, say so up front and we'll prioritize it.

Do you work with property managers and HOAs?

Regularly. We handle scheduled maintenance, compliance testing across multiple addresses, and consolidated reporting. If you manage several properties, we can put every backflow assembly on a single annual schedule.

Are you licensed and insured?

Yes — licensed with the California State License Board, bonded, and insured. Our license number is listed at the bottom of every page on this site.
