Water Heater Repairs in San Marcos

We troubleshoot the symptom and the system around it. That includes pilot and ignition trouble, gas control valves, thermostats, electric elements, burner service, drain valves, leaks and temperature problems. Popping or rumbling can point to sediment, while water at the base may come from a connection, valve or the tank itself. The source matters because it determines whether repair is practical.

Plan the Replacement Around the Home

True Plumbing installs 40- to 80-gallon conventional tanks, gas and electric tankless systems, propane units, power-vent and direct-vent equipment, commercial heaters and customer-supplied units. San Marcos properties range from established central neighborhoods to planned communities in San Elijo Hills and Twin Oaks Valley. We size and plan the installation around household demand, space, venting, fuel and the existing plumbing.

Tankless Conversion and Maintenance

A tankless system heats water on demand and saves floor space, but a conversion may require gas, electrical or venting changes. We inspect those conditions before recommending it. Existing tankless equipment also needs periodic descaling. Conventional tanks benefit from flushing and inspection to manage sediment and spot aging components.

Straight Repair-or-Replace Guidance

A repair may be the best value when the tank is intact and the problem is a serviceable part. A leaking tank or a unit with repeated failures points more strongly toward replacement. We explain what we found, show the options and give clear pricing before work begins.
