Who we are

Main water line work from our Diamond Bar Boulevard office

Diamond Bar Plumbers is a water line company based on Diamond Bar Boulevard. Most plumbing companies treat main line work as one service among dozens. For us it is the center of the work: finding leaks in buried pipe, repairing failed sections and replacing lines that have reached the end of their life.

In practice that means rusted galvanized pipe under 1950s homes in West Covina and Hacienda Heights, lines stressed by graded hillside lots in Walnut and Chino Hills, and long runs on large lots in Yorba Linda and Chino.

What we do

From the meter to the house

Our work covers the full length of the line you own as a homeowner. That includes tracking down hidden leaks, repairing damaged sections, replacing buried lines, rerouting pipe away from slabs and roots and swapping out corroded galvanized steel. When a line fails outright, we handle it as an emergency.

Areas we cover

We are based in Diamond Bar and work in nearby cities across the Pomona Valley and Puente Hills, including Walnut, Rowland Heights, Hacienda Heights, Chino Hills, Pomona, West Covina, Brea, Yorba Linda, Chino and City of Industry.

Why call us

Why homeowners near Diamond Bar call us

Working here since 2005

We have taken water line calls in Diamond Bar and its neighboring cities since 2005, so we know which provider, county and permit office each address deals with.

A real person answers

Our phones are covered around the clock, so a failed line at night does not mean waiting for the office to open.

Same-day visits

Ask for a same-day visit when you call. A failed line does not have to wait for next week.

Emergencies come first

When water is surfacing or the house is dry, that job moves to the front of the line.

What to expect

What happens when you call about your water line

  1. A few quick questions

    What you are seeing, when it started, and whether you know where the main shutoff is.

  2. Help with the shutoff

    If water is running, we talk you through finding and closing the main valve.

  3. A time we can be there

    We tell you when to expect us, which is often the same day.

  4. No price over the phone

    We give a number after we have seen the line, not before, because every run is different.
