Repiping & Water Lines

Repiping means replacing a home's old water supply lines with new pipe, usually copper or PEX. A whole-home repipe replaces all the supply lines, while a partial repipe replaces the worst sections. It's the lasting fix for recurring leaks, low water pressure, and rusty or discolored water from aging galvanized pipe. We handle permits and California code compliance as part of the job.

Your home may need repiping if you've had more than one leak (including slab leaks), your water looks rusty or discolored, pressure is low throughout the house, or you still have original galvanized steel pipe. Galvanized pipe corrodes from the inside, so when one section fails, others are often close behind. A plumber can check your pipe material and condition and tell you whether spot repairs still make sense.

Both PEX and copper are reliable choices, and the better one depends on your home and goals. PEX is flexible, needs fewer fittings, and is usually quicker to install inside finished walls. Copper is a long-proven rigid pipe that many homeowners prefer. We install both to California code and will walk you through the trade-offs for your house before you decide.

Most whole-home repipes on single-family houses take about two to five days, and larger or two-story homes can take a week or more. The time depends on the home's size, the number of bathrooms, the pipe material, and how much wall patching is needed. Partial repipes are often faster. We give you a timeline along with your up-front quote before work begins.

Yes, repiping a house generally requires a plumbing permit and inspection from your city or county. The inspection confirms the new lines are installed and tested to code. First Call Plumbing & Restoration (CSLB Lic. #798425) pulls the permit and coordinates the inspection as part of every repipe.
