Answers first

Questions homeowners ask — pipes, mains & gas lines in California

How do I know if my house needs repiping?

The usual triggers are the material itself (galvanized steel or polybutylene), repeated pinhole leaks across the system rather than at one spot, and discolored water at multiple fixtures. One leak in one place is a repair; a pattern across the house is a repipe conversation.

Who owns the water service line?

Typically the property owner owns from the meter to the house, and the utility owns from the main to the meter — but the boundary and the rules around lead service lines vary by jurisdiction. Confirm with your water utility before authorizing work.

I smell gas — what do I do first?

Leave the building. Do not switch lights or appliances on or off, do not use a phone inside, and do not look for the leak yourself. Call your gas utility's emergency line from outside — utilities respond to suspected leaks at no charge. Only after they have made it safe does a licensed plumber do the repair.

How often should a sump pump be tested?

Pour a bucket of water into the pit at least twice a year, and before the wettest season in your region. The failure you care about is the one you discover during a storm.

Who handles the permit for plumbing work in California?

The licensed contractor pulls the permit — never the homeowner. If a contractor proposes skipping a required permit, treat that as the signal to stop and verify the license.

What warranty applies to the work?

Whatever the contractor offers in writing — PlumberCalifornia is not a party to the agreement. Ask for labor and parts warranty terms in the quote, and keep the license number with the paperwork.

How does the callback request work?

The 30-second form asks for a name, ZIP and the number to reach you on. The request routes to an independent licensed professional covering that area, and they call you back. Consent for marketing contact is optional — the request goes through with or without it.

Which areas does PlumberCalifornia cover?

All of California: the site lists every covered city with real ZIP codes, the county permit authority and nearby coverage, so requests route to a professional already working that area.
