From water heater repair to sewer line replacement, we offer a wide range of residential and commercial plumbing services across The North Bay
Stop overpaying plumbers. West Coast Plumbing delivers the professional drain cleaning and a free full-line camera inspection at the best price in town— so you know exactly what’s going on inside your pipes before small problems become big ones.
The Air District is changing what can be installed here, and the dates just moved again. Nobody has to replace a working water heater, and there is no inspection coming.
We keep a plain-English breakdown updated every time the rule changes — what it covers, who is exempt, and what the local rebates are actually worth. No scare tactics, just the answer.
Draft — not adopted
Existing water heaters are not affected either way. Last updated September 1, 2026.
Work with a team of local professionals who put honesty and care at the forefront of every project they work on.
From your kitchen sink to your sewer line, we’ve built a reputation for clear communication and quality workmanship that lasts.
We’re proud to be the plumber Sonoma, Marin, and Napa County families recommend to their friends and neighbors.

Called at 8am about a backed-up drain. West Coast was at our house by 10am. David was fabulous from start to finish.
Quick, efficient, accommodating — and never tried to upsell me. Rare honesty for a plumbing service. Highly recommended.
