The Water Heater Maintenance is something most of us take for granted, until it suddenly stops working. As cold water imposes reality, we desperately dial a plumber or rush off to get a new water heater. All this might be avoided with some regular preventive maintenance.
Water heater maintenance is easy to overlook because the tank just sits there and has no moving parts to worry about. Inside though, two things are constantly attacking your water heater: sediment and rust.
Most steel water heater tanks are lined with glass to prevent rust, but the glass lining is never perfect and constant temperature fluxes cause minute openings. When water eventually penetrates the lining, the tank begins to rust.
Also, the heated water causes calcium carbonate to form. It’s a type of limestone you can probably see inside your old teapot. As it forms, the calcium carbonate settles to the bottom of the tank. In gas-powered tanks, it eventually becomes thick enough to reduce heating efficiency. In electric tanks, it forms a hard crust that renders the element useless.
To keep your water heater operating correctly and extend its life by years, you need to carry out regular maintenance.
How to Drain and Clean the Tank
The first task is to drain the tank at least once a year. This will remove most of the sediment collecting at the bottom of the tank. To drain the tank, follow these steps:
- Shut off gas or electricity to the water heater.
- Attach a garden hose to the drain valve at the bottom of the tank.
- Close the incoming cold water valve at the top of the tank.
- Open the pressure relief valve on the tank to break the vacuum.
- Open the drain valve on the tank and drain it.
- When finished, reverse the process, remembering to not turn on the gas or electricity until the tank has refilled.
If your tank is located in the basement or a low area that prevents gravity flow draining, you can purchase a small electric pump in plumbing shops or large home supply centers. With this, you can pump the water from your tank to an outside drain or to an upstairs sink.
