T&P Valve and Safety Testing in Olympia, WA
The temperature and pressure relief valve keeps your water heater from building dangerous pressure. We test it by lifting the lever and checking that it opens and reseats. A valve that leaks or will not open gets replaced. We also check that the discharge pipe runs to an approved location. Expansion tanks are checked for proper air charge where installed.

Electric Water Heater Element Service in Olympia, WA
Electric water heaters use upper and lower heating elements controlled by thermostats. Sediment can coat the lower element and cause it to fail. We test both elements and thermostats with the power off and replace parts as needed. A failed element is often the reason for lukewarm water or running out of hot water fast. Proper testing avoids replacing parts that are still good.
Attic and Garage Water Heater Maintenance in Olympia
Many homes have water heaters in garages or attics, where heat, cold and tight access add stress to the unit. Attic units need working drain pans and drain lines to prevent ceiling damage if the tank leaks. We check the pan, drain line, venting and access platform. Garage units should be raised and protected where required for gas appliances. We confirm your setup meets local code.
Anode Rod Inspection and Replacement in Olympia
The anode rod is a sacrificial part in your water heater designed to corrode instead of the tank itself. Depending on your water chemistry, these rods can wear down faster than expected. During maintenance, we inspect the anode rod's condition and recommend replacement if necessary. A healthy anode rod is key for preventing rust and extending the lifespan of your water heater tank, saving you from a costly full replacement.
Tank Water Heater Flushing in Olympia
Hard water leaves calcium and magnesium sediment at the bottom of the tank. This layer insulates the water from the burner or lower element, wasting energy and causing popping sounds. We connect a hose to the drain valve and flush the tank until the water runs clear. For heavy buildup, we may stir and flush in several cycles. A clean tank heats faster and runs more quietly.
Gas Water Heater Burner and Venting Check in Olympia
Gas water heaters need a clean burner and a proper vent to run safely. We inspect the burner flame, clean the combustion chamber and check the thermocouple or flame sensor. The vent is checked for proper draft and secure connections. Blocked or loose vents can let carbon monoxide into your home. We also check the gas line and shutoff valve for leaks.
Water Heater Anode Rod Inspection in Olympia
The anode rod is a sacrificial part that protects your water heater tank from corrosion. During maintenance in Olympia, we inspect the condition of the anode rod and recommend replacement if it's heavily depleted. Replacing a worn anode rod can extend the life of your water heater by several years, preventing costly tank leaks.
