Reliable San Mateo, CA Water Heater Repair And Replacement With Facility Plumbing & Drain
Diagnosis, Repair, And Full Replacement For Tank And Tankless Systems
A failing water heater in San Mateo County, CA rarely announces itself politely. Rust-tinted water, a pilot light that won’t hold, or lukewarm showers at peak morning hours are signs the unit is past a quick fix.
At Facility Plumbing & Drain, we handle water heater repair and replacement for both traditional tank systems and tankless units. We also work on installations in tight utility closets or garages.
Our technicians scope the problem first.
Sediment buildup, a failed heating element, a corroded anode rod, or an unsafe pressure relief valve can produce similar symptoms but require different solutions.
When repair isn’t the right call, we walk you through replacement options sized for your household’s actual demand — not the nearest standard spec on the shelf. We also handle the full installation process. That includes water line connections, venting where required, and code-compliant pressure settings before we consider the job finished.

Serving Homes And Businesses Across Our Community
A water heater that stops producing hot water or starts leaking isn’t just an inconvenience — it disrupts showers, laundry, and dishwashing until the problem is fixed. Our San Mateo County, CA water heater repair and replacement services cover both diagnostics and hands-on repairs.
Whether you’re dealing with inconsistent water temperature, a pilot light that will not stay lit, sediment buildup slowing recovery time, or a unit that has reached the end of its service life, we assess the equipment’s condition first.
Then we walk you through your options.
We handle tank and tankless water heaters for homes, multi-unit buildings, and commercial facilities. After evaluating the unit, we give you a clear picture of the situation. We explain whether repair makes sense or if replacement is the more cost-effective path based on the unit’s age and condition.

Water Heater Repair And Replacement Services
We start by inspecting the full unit, including the burner assembly, thermostat, anode rod, connections, and venting. Only then do we recommend a course of action for your water heater repair or replacement.
For repairs, we address the specific failure point rather than applying a short-term patch that leaves underlying wear unresolved.
The goal is a fix that holds.
When replacement is the right call, we size the new unit to match your household or facility demand — so you’re not paying to heat a larger tank than you actually need.
Our water heater services include proper disposal of the old unit, connection testing, and a final check before we consider the job complete.
