Reasons To Flush A Water Heater Tank Annually
The manufacturers of water heaters recommend getting your water heater flushed annually. The tank of the water heater tends to get scaled with sediments if not flushed from time to time. Sediments of lime and calcium build inside the tank if not cleaned at regular intervals. This impedes the performance of the water heater as well. Annual flushing ensures a long life span of you water heaters. According to Steve Hyde, owner of Washington Water Heaters in Bellevue, Washington – “Sediment builds up in the tank, usually at the bottom, and that insulates it from the flames that are pounding on the bottom of the tank to heat the water.” The heater works harder to heat water and the impact is seen in the power bills.
Some of the companies manufacturing water heaters also send yearly reminders to clients to get their water heater flushed on an annual basis. Frequency of flushing also depends on the quality of water that is supplied to homes of a particular region. The Seattle area for example is known for supplying some of the cleanest water in the nation. Areas that have a supply of hard water through municipal lines require frequent flushing. If you are not sure about the frequency of such flushing, it is better to stick to the manufacturer’s recommendations unless a reliable service provider suggests otherwise. If the sediment build-up is quite thick inside the tank, you might see the debris coming out of you taps as well. Sediments in your pipes can have other consequence. They limit the space inside the heater. In Texas, dirt daubers (wasps) and moths build nests in the pipes of the heater with thick scales. Sediments would cause the water pressure to go down and pipes to bust in due course.
