Who We Are
The Water Heater Replacement Company Cotati Homeowners Trust
Masters Plumbing Service is a licensed, fully insured plumbing service operating across Cotati, CA. Our team consists of master plumbers and apprentices who carry active CA licenses and complete annual code-update training — because the plumbing code changes, and your contractor should know about it.
Our Cotati service hub keeps technicians staged throughout the area so we're not driving 45 minutes to your house while a burst pipe runs unchecked. Fast arrival isn't a slogan for us — it's a logistical commitment backed by how we staff and deploy our crews.
Every Masters Plumbing Service technician working in Cotati is background-checked before hire, uniformed, and arrives in a marked vehicle. You know who's coming and you can verify their credentials. That's the standard we hold ourselves to — not because it's legally required, but because it's what we'd want if we were the customer.

Warning Signs
Don't Ignore These — They Cost More the Longer You Wait
Most plumbing problems give warning signs before they become expensive disasters. Here's what Cotati homeowners should watch for — and why waiting makes every one of them worse.
01
Slow Drains Throughout the House
A single slow drain is usually a localized clog. Multiple slow drains at once signal a main sewer line issue — the kind that backs up into your lowest fixtures if ignored.
02
Water Bill Spike With No Explanation
A sudden 20–40% increase in your water bill with no change in usage habits often means a supply line leak inside the structure or underground — invisible but actively running.
03
Discolored or Rusty Hot Water
Brown or rust-colored hot water is almost always a water heater with a depleted anode rod or internal corrosion — both signs the unit is approaching failure.
04
Low Water Pressure at Multiple Fixtures
Pressure drops at one fixture point to a clog or a partially closed supply valve. Pressure drops at multiple fixtures simultaneously suggest a main supply problem or significant scale buildup inside supply lines.
05
Running Toilet That Won't Stop
A toilet that runs constantly wastes 26–200 gallons per day depending on severity. That's $15–$100 per month per toilet — for a repair that typically costs far less than one billing cycle of waste.
06
Wet Spots or Stains on Ceilings and Walls
Moisture stains on ceilings or walls that reappear after painting point to an active supply or drain line leak inside the structure. The visible damage is usually much smaller than the wet zone inside the wall.
07
Gurgling Sounds in Drains or Toilets
Gurgling when a toilet is flushed, or when the washing machine drains, points to a venting issue or a partial main line blockage. Air displaced by water flow has nowhere to go and creates the gurgling sound.
Here's a look at what our Cotati, CA-licensed plumbers do every day — and why the depth of our service offering means you call one company instead of tracking down three.

— B. Harrington, Cotati
Cotati, CA · Water Heater Repair
★★★★★
"Three slow drains throughout the house, plus a gurgling toilet when the washer ran. Masters Plumbing Service's tech accessed the main cleanout, ran a camera, and found root intrusion at two clay tile joints and a partial grease plug at 28 feet. Hydro-jetted the full line, re-scoped to confirm, and the system has performed perfectly for four months. Written service report with the camera footage timestamp is a nice touch."
— F. Okonkwo, Cotati, CA
Cotati, CA · Leak Detection / Drain Service

FAQ
What Cotati Customers Ask Before Calling
These are the actual questions our dispatchers and technicians answer every day in Cotati, CA.
For emergency calls in Cotati, our dispatch target is 30–60 minutes from the moment we confirm your address and assign a technician. We stage technicians throughout Cotati — not at a single central shop — which keeps our actual drive times short. Non-emergency scheduled calls are booked in specific time windows so you're not clearing your whole day for a "sometime between 8 AM and 5 PM" appointment.
Flat-rate pricing means we price the outcome, not the hours. We've invested in technician training and truck stocking so we can work efficiently — and pass that efficiency to customers through competitive flat rates rather than inflating an hourly clock.
Masters Plumbing Service's emergency dispatch in Cotati, CA is available around the clock, 365 days a year. The emergency services we handle after hours in Cotati include: burst and ruptured pipe repair, active sewer backups, water heater failure (gas and electric), major drain blockages affecting multiple fixtures, gas line leaks (after utility shutoff), frozen pipe response, and main water line failures.
Every technician Masters Plumbing Service dispatches in CA holds an active state plumbing license. Masters Plumbing Service carries general liability insurance and workers' compensation coverage on all field personnel. We can provide license numbers and a certificate of insurance on request — and we encourage you to verify licenses with the CA licensing board before any plumber begins work on your property, regardless of which company you hire.
Yes. Every repair and installation performed by Masters Plumbing Service in Cotati, CA carries a written workmanship warranty — the specific term and scope are documented on your service receipt. Parts warranties from the manufacturer apply in addition to our workmanship coverage. If a covered repair fails within the warranty period, you call us and we return to fix it at no charge.
Our dispatcher will walk you through protective steps for your specific situation when you call. That's part of why we answer live — not just to take your information, but to help you prevent additional damage while our technician drives to you.
If the meter test confirms water loss, call us before opening any walls. Our acoustic and thermal detection equipment locates leaks to within inches in most cases — which means a small, targeted access opening instead of a speculative wall demolition.
Yes. Masters Plumbing Service serves both residential homeowners and commercial property owners, managers, and operators throughout Cotati, CA. Our commercial team handles restaurant drain and grease trap service, office building fixture repair, multi-unit residential systems, backflow preventer testing and certification, commercial water heater service, and after-hours emergency response for business properties.
Cases where excavation is required: fully collapsed pipe sections, severe pipe belly (negative grade that holds sewage), and pipe offset too severe for lining to bridge. We scope before recommending anything and show you the camera footage so you can see which category your pipe falls into.
Masters Plumbing Service handles the full range of water heater services in Cotati, CA: diagnosis and repair for gas and electric tank units (thermocouple, pilot assembly, gas valve, heating elements, thermostats, T&P valve, anode rod); tankless water heater repair including igniter assemblies, flow sensors, heat exchanger descaling, and error code diagnosis; and full replacement for units beyond economic repair, including conversion from tank to tankless where the infrastructure supports it.
Common residential repairs — fill valve replacement, flapper, faucet cartridge, drain clearing — are typically in the $100–$300 range. More complex work like slab leak repair, sewer line lining, or water heater replacement varies by scope and we walk you through the numbers on-site. No work begins until you've approved a written price.
Pulling permits matters beyond legal compliance: an unpermitted plumbing repair can void homeowner's insurance coverage for related water damage and can create title issues when selling the property. We handle permit procurement and inspection coordination as part of the job — permit costs are disclosed in your flat-rate quote.
