Who We Are

Family-Owned Since 1978

A licensed plumbing contractor and certified backflow testing company working across Southern California since 1978 — from our shop in Rosemead.

Our Story

Built on Repeat Customers

Lue Plumbing opened in 1978 the way most good trade businesses do — one licensed plumber, a truck, and a reputation that traveled by word of mouth. Decades later we've grown, but the thing that built the business hasn't changed: people call us back, and they send their neighbors.

The backflow side grew out of that. Customers kept getting notices from their water district and couldn't find someone certified to handle it properly. So we got certified, and Alhambra Backflow became the specialty half of what we do. Today we test and certify assemblies for homeowners, restaurants, medical offices, and property managers across Southern California.

We're still family-owned. When you call, you're not routing through a call center — you're talking to the people who'll actually be doing the work.

We Help Certify Other Testers

Backflow testers don't get certified by taking a written test alone. They have to demonstrate, on real assemblies, that they can run a test correctly — and someone qualified has to sit there and watch them do it.

That's the rig in the photo. We proctor those exams — an ABPA-certified proctor position, which means the testers working around Southern California may well have been signed off by us.

Worth knowing when you're deciding who to trust with a compliance deadline.

Staff

Inspector, Head of Security

Every family business has one employee who does no measurable work and is completely irreplaceable. Ours is named Inspector, which in a backflow company is either a joke or a job title, depending on the day.

He sleeps through most of the shift and greets everyone who comes through the door. The rest of the crew shows up on time.

How We Work

The Standard We Hold

Plumbing is one of the few trades where the customer usually can't verify the work themselves. That puts the burden on us to be worth trusting.

We Diagnose Before We Quote

The visible symptom is often not the actual problem. We find the cause first, then price the fix — instead of replacing the easiest part and hoping.

We Explain It Plainly

You'll get the reasoning in language that makes sense, including what happens if you wait. No pressure, no jargon used as leverage.

We Do It Once

Proper materials, proper installation, permits when required. A repair that fails in eighteen months costs everyone more than doing it right the first time.
