Of all the things that civilization has brought us, including sliced bread, hot water may be the very best. It’s certainly up there, without a doubt. So, it would follow that if you really value that hot water, you’d want to care for and protect the equipment that makes it possible.
Whether you’re doing it as a bit of regular maintenance or because you’re leaving a vacation or rental home unoccupied, draining said water heater is one of the easiest things you can do to keep that particular appliance in tip-top shape.
Most water supplies contain lots of random minerals in various quantities. Get enough of them together and you get “hard” water, which really just means it has a lot of minerals in suspension. Over time, these minerals settle out and land in the bottom of your hot water heater. Given enough time, a layer thick enough to interfere with the function of the appliance will develop.
Before you reach that point, a maintenance flush is in order. How often you flush depends on a lot of factors, including the size of the hot water heater and how often it’s used. A good rule of thumb is to flush your water heater every six to 12 months, whether you think it needs it or not. It’s better to wash those particles out before they become a problem.
Of course, draining your water heater isn’t just about flushing particles. If you’re going to leave a house sitting empty for a significant period of time, you should empty the hot water tank. Draining the hot water heater is an important part of winterizing vacant homes, it helps to protect the heater itself from damage due to low temperatures. When the water lines are also drained, emptying them completely keeps them from freezing and bursting.
Draining a hot water heater is a really simple process. In fact, the hardest part is working with water hot enough to scald you. Before you even get started, snagging some thick dishwashing gloves or other heavy, insulated and very importantly, non-absorbent, form of hand protection.If you’re wearing thick cotton gloves, for example, they’ll just hold that extremely hot water against your skin.
With your skin adequately protected, draining or flushing your hot water heater is a piece of cake. Just follow these steps:
If you’re draining your hot water heater because you’re leaving the house empty for a while, you’re essentially done with the water heater now (winterizing a home is a whole different blog). If you’re flushing sediment, keep going until you see the water run clear, then do all those steps in reverse for a hot water heater with shiny clean insides and hot water.
