Water Line Repair & Replacement in Rancho Cucamonga
Cracked, corroded, or leaking main water line? Billy answers 24/7 and is often on-site within 60 minutes.
Your main water line runs underground from the city meter to your house. When it fails, you usually don't see it right away. You notice a soggy patch in the yard that never dries, a water bill that jumped for no reason, or a faint hiss near the hose bib when everything inside is off. By then, water has been leaking for a while.
Rancho Cucamonga is hard on water lines. Our water carries a lot of minerals, and homes built before 1980 often still have galvanized steel pipe that corrodes from the inside out. In older neighborhoods with mature trees, roots find small joints in the line and pry them apart. Shifting soil around slab foundations does the rest.
W.P. Plumbing is owner-operated. When you call, you get Billy, not a call center. W.P. Plumbing is licensed, bonded and insured. You get honest upfront pricing before any work starts and free estimates on main line replacements. If the line can be repaired instead of replaced, that's what we'll tell you.

Frequently Asked Questions
How do I know if my main water line is leaking?
Shut off every fixture in the house, then check your water meter. If the dial or leak indicator is still moving, water is going somewhere. Pair that with a soggy yard spot, a spike in your bill, or low pressure at every faucet, and the main line is the likely culprit. Call (909) 727-2959 and we can confirm it with a pressure test.
How much does water line repair cost in Rancho Cucamonga?
It depends on the depth of the line, the pipe material, and whether a spot repair will hold or the whole run needs replacing. We give you a firm written price before any digging starts, and estimates on full main line replacements are free. No surprise charges when the job is done.
Should I repair my old galvanized water line or replace it?
If your home was built before 1980 and still has the original galvanized steel line, replacement usually makes more sense. Galvanized pipe corrodes from the inside, so a patch in one spot often means another leak a year later. We replace failed galvanized lines with copper or PEX and back the work with our workmanship guarantee.
Do you have to dig up my whole yard to replace a water line?
Usually not. Because we locate the leak precisely before excavating, spot repairs typically need one small hole. For full replacements, we plan the run to disturb as little landscaping and concrete as possible, and we backfill and clean up when the line has passed its pressure test.
