Water Heater Pressure Tank

The tank has two sections that are separated by a rubber valve.

Water heater pressure tank. The water heater expansion tank serves as an overflow receptacle by absorbing excess water volume that occurs when water is heated as well as absorbing fluctuations in the incoming water supply pressure. Constant fluctuations in water pressure can be dangerous and they can damage the water heater properly installing a thermal expansion tank can solve all these issues. Flotec fp7120 vertical pre charged pressure water tank 35 gallon. 4 6 out of 5 stars 179.

Water heaters come equipped with a temperature and pressure relief valve also known as a tprv. This water heater expansion tank stops hot water from backflowing into the cold water line and prevents hot water from escaping through the pressure relief valve and onto the floor.

The tank utilizes a thick diaphragm to keep water separate from pre charged air and to help reduce air loss. When water is heated inside your water heater it expands. When your water thermally expands a water heater expansion tank prevents unwanted increases in pressure. This valve allows water or steam to escape from the water heater if the temperature or pressure gets.

Since water expands when it is heated due to thermal expansion the water heater creates extra water volume every time it heats water. This ultimately protects it from damage. This condition significantly increases the pressure of water pipes and can lead to damage to pipes household appliances and water heaters. Amazon s choice for water pressure tank.

That extra water volumeraises the pressure in your water heater to dangerous levels. The water worker 20 gal. A 40 gallon water heater with 80 psi line pressure will build to a pressure of 145 psi with a temperature increase of 16 f. As the temperature increases the maximum working pressure for which the water heater was designed 150 psi can be exceeded.

Water expands by roughly 2 as it heats up from 50 f to 120 f. Pressurized well tank is pre charged and designed to maintain its air charge for years to provide easy upkeep. The expansion tank serves as a backup system to prevent overworking your plumbing.
