Due to Marin's hard water, annual maintenance is the single most important thing you can do to extend the life of your water heater. Our tune-up focuses on removing mineral buildup to keep your system efficient and prevent premature failure.
The minerals in Marin's water supply create a layer of sediment at the bottom of your storage tank. This forces the burner to work harder to heat through the sediment layer, wasting energy and causing the tank to overheat and fail years ahead of schedule.
Sediment buildup is the #1 cause of premature tank failure in Marin
Tankless water heaters and heat pump models have intricate internal heat exchangers that scale up quickly in Marin's hard water. Annual descaling is essential to maintain flow rates, efficiency, and manufacturer warranty compliance.
Annual descaling maintains efficiency
Annual maintenance isn't just about cleaning — it's a systems inspection. We check T&P relief valves, gas connections, anode rods, and pressure levels. Catching a failing T&P valve or a failing expansion tank before they cause damage saves you thousands.
Prevent expensive water damage
We flush your storage tank completely to remove mineral sediment. For tankless and heat pump units, we descale the heat exchanger using a citric acid flush.
We test the temperature and pressure relief valve, inspect the expansion tank, check all connections for leaks, and verify proper venting and gas pressure on gas units.
We inspect and replace the sacrificial anode rod if needed — this is what prevents your tank from corroding from the inside. We also clean filters on tankless and heat pump models.
We verify the unit is heating to the correct temperature, check for any error codes on smart units, and provide a written service report documenting what we found and any recommendations.
Flush sediment, inspect and replace the anode rod, test the T&P valve, and check for corrosion at all fittings. We service all major brands including Bradford White and Rheem.
Clean the air filter, inspect the condensate drain, check refrigerant levels, and verify compressor operation. Heat pumps need regular filter cleaning — especially in dusty Marin garages — to maintain efficiency.
A small investment in annual maintenance prevents expensive emergency replacements. Schedule your service today and protect your hot water system from Marin's hard water.
