Flextrol FTT5 Thermal Expansion Tanks-for Hot Water Heaters, Carbon Shell, Stainless Steel 3/4 Inch MIP Connection, Butyl Diaphragm, 150 PSI, 210 Degrees Fahrenheit, Almond Color, 2.1 Gallons

Last update was on: Tuesday, January 7, 2020

Size:2.1 Gallons |  Color:Almond

What is Thermal Expansion?
When heated, water expands. Under normal circumstances, a 40 Gallons hot water heater creates roughly an additional half gallon of water when heated (with no demand). In the past this expanded water would flow back into the public water supply. However, in many countries, where applicable by code, a backflow preventer is required, creating a closed system and a new problem as this extra half gallon of water is not compressible. When an expansion tank is installed the excess water enters the pre-pressurized tank. As the temperature and pressure reaches its maximum, the diaphragm flexes against an air cushion (air is compressible) to allow for increased water expansion. When the system is opened again or the water cools, the water leaves the tank and returns to the system.

Potential Problems Without an Expansion Tank

  • Premature failure of the water heater may void the warranty of the water heater
  • Dangerous high pressure
  • leaky fittings and valves
  • collapsed center flues
  • flames out of combustion chamber
  • Unnecessary Relief Valve Discharge

Installation Options for Thermal Expansion Tanks

  • Install on the cold water side after the pressure reducing valve and between the backflow preventer and the water heater
  • Do not install in an area where leakage could cause property damage
  • The tank can be installed either vertically or horizontally. However, if the tank is to be installed horizontally, then it must be fully supported independent from the piping. Failure to do so will void the warranty.
