How To Drain Your Water Heater The Significance Of Draining A Water Heater Draining your water heater is important because of the fact that it will clean out the inside of the heater, and allow clean water to be reinserted into the heater, and clean water will also come out of the heater for use. Although the water that continuously goes into a water heater in your Glendale home may be clean, the water heater can develop sediments and other deposits that can settle in the water heater, creating dirty water. Many have seen their water turn discolored because of the things inside their water heater, and this means that the water heater needs to be drained and possibly flushed. Whether a water heater has a tank or not doesn’t matter. Both a tankless water heater and a typical water heater can be flushed, even though flushing a tankless water heater may be a lengthier process that requires additional work. The Draining Process Draining of the water heater will start by disconnecting or turning off any power that runs the heater, such as gas or electric. Once the power is disconnected, then the cold water valve should also be turned off, which is on the water heater. There’s a drain valve at the bottom of the water heater, and this needs to be uncovered and a hose attached to the valve. It’s possible to capture the water in buckets or containers, but be aware of the very hot water coming out, so no one gets burned. Turn on a hot water valve before opening up the drainage valve and allowing the water to drain. Drain the water once, partially refill the heater, and allow the water to drain again. Flush the water heater, if necessary, especially if sediment is still coming out in the draining water. Once the water heater is clean, then the drain valve should be closed, and the water heater can be filled with water again. Who’s Best To Drain A Water Heater? It’s always best to have a licensed plumber drain a water heater in your Glendale home, especially since the process shouldn’t only include draining the water but maintenance as well. The rods and other parts of the water heater should be inspected by the plumber when it’s being drained to ensure the heater doesn’t have any other problems.
