Depends on your code. If you have a PRV or, as you would say, pressure reducing valve on your water supply to your house, you need an expansion tank. If your pressure is above 80 psi, you need a PRV AND an expansion tank.
A pressure relief valve or expansion tank can help control the pressure in heating systems to prevent expansion and contraction of liquid or coils. The relief valve releases excess pressure, while the expansion tank absorbs the extra volume of liquid as it expands.
Your temperature and pressure relief valve may be leaking due to high pressure or temperature in your water heater system. This can be caused by a malfunctioning valve, excessive pressure buildup, or overheating of the water heater. It is important to address this issue promptly to prevent potential damage or safety hazards.
You must have a pressure relief valve. I believe it is code nationally. I don't think you can buy a hot water tank w/o one. Expansion tank needed also if water meter has backflow preventer, check with local water authority if it does.
Your temperature and pressure relief valve may be dripping because there is excess pressure or temperature in your water heater system. This can be caused by issues such as a faulty valve, high water pressure, or overheating of the water heater. It is important to address this issue promptly to prevent potential damage or safety hazards.
To determine if the temperature pressure relief valve is leaking, check for any signs of water dripping or pooling around the valve. If there is evidence of leakage, it may indicate a problem with the valve that needs to be addressed.
Yes, an electric water heater can explode under certain circumstances, such as when the pressure relief valve malfunctions or when there is a buildup of pressure due to overheating.
If water is coming out of the top of the water heater, it may be due to a leak in the pressure relief valve or a faulty temperature and pressure relief valve. To fix this issue, you can try replacing the pressure relief valve or adjusting the temperature settings on the water heater. If the problem persists, it is recommended to contact a professional plumber for further assistance.
Symptoms of water heater pressure relief valve failure include leaking water from the valve, excessive pressure in the water heater, and hot water not being delivered at the right temperature.
Your water heater pressure relief valve may be leaking due to high pressure in the tank, a faulty valve, or excessive temperature. It is important to address this issue promptly to prevent potential damage or safety hazards.
pressure relief valve relief the excess pressure which is developed in the syatem, while pressure reducing valve reduces the pressure and supply it to the system.
Yes, they are. The term "pressure" seems to scare some people. The amount of pressure in a pressure cooker is only about 15 pounds. This, combined with the built-in relief valves, makes them safe to use.
If the bladder is bad in your expansion tank the tank will fill with water. When this happens the pressure in your furnace will exceed 30lbs and your pressure relief valve will blow off.
