![]() It may often be most cost-efficient for the customer to simply replace a waterlogged tank. Fasttasks 2 46 – The Troubleshooting Approximate Error Premature tank failure: the inside walls of a waterlogged tank can corrode and weaken from the exposure to water.Because waterlogged tanks can contain stagnant water, there can be unsatisfactory coliform samples or taste and odor complaints. ![]() Frequent cycling can shorten the lifespan of a pump. Waterlogged bladder pressure tanks contribute to the following problems: A tank is waterlogged if it is completely filled with water or has too much water to function correctly. You should also check a bladder tank to determine if it's waterlogged. If tank pressure drops abnormally, the bladder inside the tank may have a tear or hole in it. Restart the pump and run through a normal cycle to verify the setting.Check for leaks in the air charging system by dripping a soap solution on the air charging valve.Release air if the pressure is 2 psi above the pump cut-in pressure (lowest pressure in the operating range).Use caution when using an air compressor or air pump. Add air if the pressure is more than 2 psi below the pump cut-in pressure.Check the tank's pressure by placing an air pressure gauge on the air charging valve on the top of the tank.Drain the tank by opening the closest faucet.Disconnect electrical power to the pump.If it appears that a bladder tank is not operating correctly, check the tank's air charge: It minimizes pump cycling, preventing frequent starts and stops and protecting pumps from motor burnout or other water system components from damage.It maintains a desired range of water pressure in the distribution system.Periodically, the amount of air in the tank should be measured and the tank recharged if the air is too low.Īlthough a bladder tank for a typical home or smaller commercial water system will not have a very large storage capacity, it will perform several important functions: These tanks are typically precharged with air at the factory.Īs water pressure changes, the volume of air in a bladder tank contracts and expands. A bladder pressure tank contains pressurized air and water separated by a flexible membrane (bladder).
