Replacing Damaged Water Heater Tanks

A water heater tanks is set up to prevent the water pressure fluctuation. Water pressure variation can easily destroy water heater as well as water lines in homes. The water heater tank serves as an overflow receptacle. It absorbs surfeit water volume created by the water heater during the heating process. Generally water expands when heated and this creates additional volume. This extra volume of water will develop excess pressure within the plumbing system. The excess pressure can easily destroy fixtures, water heater and water piping ultimately.


At times it is quite simple to notice that your water heater tank requires replacement. You can’t repair a tank that has corroded and is leaking. Most of water heater tank problems can be repaired. However, repairs may not be possible at time. Repairing a water tanks that is worn out is more expensive than replacing it with a new one. Before making a decision about replacing damaged water heater tanks versus repairing, you should look at your water heaters’:




You can check this on the serial number. The serial numbers of water heater contain the date the tank was manufactured. If the serial number starts with a letter, it corresponds to a month. The two digits immediately following are the year. For example L-98 or 1298 implies that the tank was manufacture in December, 1998, or (9852) – the last week of December, 1998. Most of water heater expansion tanks can last for eight to twelve years. If you have a tank with at least 12 years and has problems, it would be wise to replace it.


Anode rod


The aluminum or magnesium anode inside a water heater tank is mainly designed to attract the tiny electrical currents that are in the hot water. During the process of attracting the current, the rods corrode instead of the walls of the tank. This assists the tank together with the fittings to last longer.


If the anode has no metal or little metal left around the steel core wire, there is higher possibility that the tank is damaged. Replace it.


Temperature settings


High temperature speeds up the rate of corrosion. Setting the thermostat of your water heater to more than 130 temperature increases the rate of corrosion.


If the temperature has been at that level or higher for at least 8 years, the damage cannot be repairable. Replacement is the only alternative.


Replacing damaged water heater tanks is the best option than repairing them. Repairing a damaged tank will cost you more than replacing it with a new one. Check the anode, age and temperature setting of your tank, to enable you decide whether your damaged tank needs repair or replacement.
