New Construction Plumbing in Hayward & the Tri-Valley

Yes. We work from the approved plans, keep the GC posted on where the plumbing stands, and line up our work with framing and the other trades so the plumbing is ready when each inspection comes up.

Rough-in is the underground work: drain and water lines set before the slab is poured or the floor goes in. Top-out is everything that runs through the framing before the walls are closed, like drain, waste and vent pipes, supply lines and valves. Finish is the last stage: fixtures, faucets, the water heater and appliance connections. There's usually an inspection at each stage.

Often, yes. It depends on the size and condition of the existing lines and on what the city and the utility require. We camera the existing sewer, check the water service, and tell you whether the ADU can share them or needs its own.

We do the plumbing on your property and coordinate with whoever provides the service, which depends on the address. In Dublin, DSRSD provides both water and sewer. In Pleasanton, the City runs both. In Livermore, water comes from either Livermore Municipal Water or Cal Water. In Hayward, most properties get water and sewer from the City, but some are on EBMUD water or the Oro Loma Sanitary District sewer. We confirm the providers for your lot early so their requirements are part of the plan.

Yes. We run gas piping from the meter to the house and to each appliance, and we're PG&E OQ qualified. PG&E sets the gas meter, and we coordinate with them on the connection.
