Water Heater Relief Tank

A hot water heater expansion tank is the cost effective solution to thermal expansion and high water pressure.

Water heater relief tank. Open the drain valve on the water heater then open the hot water tap at a nearby sink to release the vacuum on the tank. Extended inlet model for installations with thick insulation. The expansion tank is designed to handle the thermal expansion of water as it heats up in the water heater preventing excessive water pressure. Rheem high efficiency condensing gas water heater.

The excess water volume instead of causing too much pressure on the plumbing rushes into the expansion tank and lowers the pressure in the water heater to safer levels. Electric water heaters are more efficient and cheaper up front than gas water heaters. Natural gas water heaters are more affordable long term and will continue to work in a power outage. Temperature pressure relief valve and thermal expansion the temperature pressure relief valve is a safety feature designed to operate as an emergency relief control and not as a constant thermal expansion control.

When no water exits the discharge pipe from the t p valve close the drain valve and remove the garden hose. 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. You install the expansion tank down the line from the inlet valve that sends hot water into your home. When your water thermally expands a water heater expansion tank prevents unwanted increases in pressure.

A 40 gallon gas water heater providing an ample supply of water to households with 2 4 people. Watts temperature and pressure relief valve provides fully automatic temperature and pressure relief protection for hot water storage tanks and heaters up to 105 000 btu hr. Soft seated and spring loaded. This ultimately protects it from damage.

With an efficiency rating of 80 this is rheem s most efficient tank type gas water heater exceeding energy star phase ii requirements. Since water expands when it is heated due to thermal expansion the water heater creates extra water volume every time it heats water. Featuring a honeywell electronic. If water pressure gets to high it can damage valves in plumbing fixtures joints in supply pipes and the water heater itself.

Place a bucket under the discharge pipe connected to the valve to collect any water and open the t p valve. The tank has two sections that are separated by a rubber valve. If you need to replace your hot water tank at home there are a range of options to fit your space and budget.
