A property owner may need a plumber for many reasons. However, one of the less familiar problems is water heater failure. Modern water heaters are extremely reliable and tend to last for a couple of decades. However, when they fail, they tend to do so spectacularly. In fact, most of the calls for water heaters repair in Mclean occur because the unit has developed some sort of leak. Leaks in the water heater happen around weak spots such as the seams that join the top or bottom and the various pipe connections.
One reason that a water heater can fail is the buildup of mineral deposits. Minerals such as lime and calcium come from hard water. They get into the local water table when rain and runoff percolates through soils that are rich in these minerals. Deposits can be avoided by having a plumber service the unit annually. Service should include the flushing of the tank, so any minerals are washed out. Service should also include testing certain items such as the pressure relief valve. This is a safety valve designed to prevent the accumulation of excessive internal pressure. If the valve fails, then the tank could explode if too much heat builds up inside it.
Another reason to consider water heaters repair in Mclean is a failing electric unit. Electric water heaters have electrodes inside the tank which heat the water. There is a chance that these electrodes can short circuit and place the unit in a low voltage circuit. This forces part of electrode to continue heating because it circumvents the controlling thermostats. The primary issue with this situation is the chance of scalding water coming from a tap. Manufacturers handle this concern by placing a temperature sensor on the tank that trips off the main power when the tank gets too hot. A plumber will fix the problem by replacing the damaged elements.
One area of concern with gas burning units is the exhaust system. A poor exhaust will affect the way the gas burns and this lowers heating quality. This occurs because the flame requires some oxygen, but a blocked flue prevents the proper flow of air. An experienced water heater technician can eliminate the blockage and get the unit heating properly. Get more information about water heaters from the professionals at website domain.
