Lower start temperatures should only be used if the entire contents of the water heater are drained on each use.
Watts water heater expansion valve.
When water is heated it expands due to a phenomenon known as thermal expansion.
We offer a range of expansion tanks for potable and non potable applications.
Asme ansi and csa aga approved relief valves protect the water heater from excess pressures and temperatures by discharging water.
They are used to prevent plumbing system and or water heater damage as well as unnecessary relief valve discharge caused by excessive pressure from thermal expansion.
Here is a water heater with a watts 210 valve.
Expansion tanks are designed to safely absorb the excess water created and prevent relief valves from triggering.

Our potable water expansion tanks are designed to absorb the increased volume of water created by thermal expansion and maintain a balanced pressure throughout the potable water supply system.
This type of valve is used instead of a temperature pressure relief valve tpr and it shuts off the gas if the water heater over pressurizes or if the water heater gets too hot.
T p valves used on residential water heaters are typically designed and manufactured to relieve pressure at 150 psi and temperature at 210 degrees f.

Series lfbrvm1 combination ball valve and relief valve is an easy to install two in one device used to shut off the water supply to the water heater and to provide protection against excess water pressure caused by thermal expansion.
Complies with lead free installation requirements.
Expansion tanks are designed to safely absorb the excess water created and prevent relief valves from triggering.
Series lf210 5 lead free automatic gas shutoff valves are used in gas water heater applications to protect against overheating water in the domestic hot water supply heating system.
We offer a range of expansion tanks for potable and non potable applications.

Relief valve the set pressure of the t p valve or the secondary relief valve setting.
The last line of defense for pressurized equipment temperature and pressure t p relief valves protect equipment from excess pressure and ultimately catastrophic failure.
Watts potable water expansion tanks are de signed to absorb the increased volume of water created by ther mal expansion and to main tain a balanced pressure throughout the potable water supply system.
When water is heated it expands due to a phenomenon known as thermal expansion.
The watts 210 valve is no longer approved for use in the city of los angeles.
Set the cold water start temperature to 90 f.
