A burst main, sewage backing up through the floor drain, a water heater flooding your utility room at 2 AM — these don't wait for business hours. Masters Plumbing Service keeps a fully-staffed, truck-loaded emergency crew in Graton 24 hours a day, every single day.

Emergency plumbing calls are the worst time to gamble on an unknown contractor. Here's what you get every time you dial Masters Plumbing Service in Graton, CA.
Every tech dispatched in CA holds an active state plumbing license and is covered under Masters Plumbing Service's liability insurance. License numbers available on request — and we encourage you to verify them.
We stage emergency crews throughout Graton on dedicated shifts — not re-routing a daytime plumber who's already running calls. When you dial at 3 AM, the on-duty emergency tech is already in a stocked truck.
Emergency surcharges are built into the flat-rate price upfront — not added to your invoice after the repair is done. You review the written quote, approve it, then we work. What you sign is what you pay.
A "we'll have to order that" on an emergency call isn't acceptable. We stock our trucks specifically to avoid it — 400+ SKUs of the most common emergency repair parts.
From burst mains to gas-assisted water heater failures, here's what our emergency crew handles around the clock in Graton, CA.
A burst pipe — from freezing, corrosion, or sudden pressure spike — releases water fast. Our crew isolates the break at the nearest shutoff, identifies the pipe material (copper, PEX, galvanized), and installs a sweated or press-fit repair rated to local code. Every supply-line repair ends with a pressure test before we leave.

We contain the affected area, clear the restriction, and provide a written scope report with camera findings. If structural repair is needed, we tell you exactly what and why before quoting it.
Tankless unit failures are diagnosed from error codes and component testing — flame rod, flow sensor, heat exchanger — with replacement parts for major brands stocked on our emergency vehicles.
Our crew carries PEX, copper, and HDPE fittings for main-line work in Graton. We schedule any required municipal inspection and provide documentation.
Every gas repair we perform in Graton, CA is documented with a written pressure test result. Permits are pulled where required; inspection coordination is included.
Freeze events often produce multiple failure points along the same run. We inspect the full exposed section before repressurizing — not just the segment that failed visibly.
We've stripped out every delay between your call and a working plumbing system. Here's the exact sequence.
Your call triggers a GPS-assisted routing lookup for the nearest available emergency technician in Graton. Dispatch confirmation and tech ETA go to you by text.
The assigned tech confirms ETA and arrives in a fully-stocked emergency vehicle. Target arrival in Graton: 30–60 minutes from dispatch. No side trips to a supply house.
The tech isolates the problem using pressure gauges, thermal cameras, or acoustic listening devices as needed, then presents a written flat-rate quote. No work starts until you approve the price.
We photograph the completed repair, provide a written service summary, and walk you through any precautions before packing up.

Woke up to my basement floor wet. Masters Plumbing Service answered on the first ring, walked me through shutting off the main while the tech drove over, and arrived in under 45 minutes. Press-fit repair on a copper elbow, pressure-tested before leaving. Done by 3 AM.
Holiday weekend sewer backup into our downstairs bathroom. Tech arrived in 52 minutes with a jetter and camera. Cleared the main line, confirmed clear on the scope, noted a root intrusion entry point for future monitoring. Clean, professional, and no runaround.
Gas water heater stopped lighting on a Sunday. Tech arrived same day, tested the thermocouple — reading 9mV, well under the 25mV minimum — swapped the thermocouple and pilot assembly in 45 minutes. Exact quoted price. Runs perfectly.
