Yes i is on the cold side. that's where it is soppose to be. And the tube (3/8) goes outside. NOT in the pan.
Blow off valve faulty or expansion tank needed at water heater.
It does not have a water flow valve in the heater plumbing.It does not have a water flow valve in the heater plumbing.
One possible reason for the temperature/pressure (tp) valve to start leaking may be from expansion of the water as it is being heated if there are check valves in the water system this is sometimes the culprit .In most water systems there is plenty of room for expansion in the distribution piping and service line and private well systems have a pressure tank that can absorb the expansion. You may have to add a small expansion tank to the water piping at the heater to solve this problem. hope this helps. Bob
I believe that the larger the hot water tank, the greater is the need for an expansion tank. Water expands as it is heated. This is why all hydronic heating systems require an expansion tank. A water heater would need expansion tank when a backflow preventer or check valve is installed in domestic cold water line directly after water meter. Some areas require backflow prevention, but not all. Have to check with local plumbing authority about that.
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.
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.
There should be a non return valve on the cold water side of the hot water tank. When there is no non return valve the water in the tank heats up and expansion of the water will cause it to travel backward up the cold water pipe thereby equalising the waterpressure normally this expansion would find its way out of the safety pressure valve. So it sounds like the non return valve needs fitting or replacing.
A TNP valve is a temperature and pressure valve found on a water heater.
The expansion valve, on your 1998 Honda Accord, is located just before the thermostat housing. You can follow the water hose from the radiator to the expansion valve.
No, an expansion tank is not required.
