Water Heater Repair & Installation

When the hot water stops, everything else waits. Integrity Plumbing installs, repairs, and replaces both traditional tank water heaters and tankless water heaters for homes and businesses in Sonoma and Marin Counties.

If you have no hot water, lukewarm water, rusty or noisy water, a leak at the tank, or a tankless unit that is erroring or short-cycling, we can diagnose the problem and tell you whether a repair will get you by or whether replacement is the better value. We work on gas and common residential units and will walk you through the options in plain language, including a free estimate, before we start.

A repair might be a failed heating element, thermostat, thermocouple, valve, or venting issue. When a tank is leaking from the body, or a unit is at the end of its useful life, replacement is usually the honest recommendation. We install standard tank heaters and tankless systems to fit the home’s needs, and we can often complete urgent repairs the same day when scheduling and parts allow.

Many homes in our service area still have older 40- or 50-gallon tanks in a garage, closet, or crawl space. Others have already switched to tankless and need service, a descaling flush, or a replacement unit. Tankless heaters can be a good fit when the home’s gas, venting, and water conditions support them; they are not automatically the right upgrade for every house. We will say so if a conventional tank is the simpler, more reliable choice for your situation.

If you have no hot water and guests are arriving, or a tank is leaking onto the garage floor, call us as soon as you can. If the tank is leaking, shut off the water supply to the heater and the gas or power if you can do so safely. Standing water around a gas appliance is not something to ignore.
