If a pressure relief valve for a boiler is accidentally installed on a water heater, it will leak like crazy from the start. These valves may look identical, but they're set to go off at 30 psi ...

Water on the floor at the water heater’s base is a sure sign of a leak. The water might be coming from the temperature and pressure relief valve (T&P valve), though.

Once the temperature and pressure relief valve at the water heater leaks, go check the pressure gauge. If the 'surge indicator' shows something at or near 150 psi, the problem is excessive pressure.

In extreme scenarios, a neglected water heater may start leaking or flooding into your home, or—if the pressure-relief valve has been blocked by sediment—even explode.

If you’ve noticed your home’s water heater leaking, it’s a problem you should take care of immediately, as the consequences of a long-term leak can be quite serious.

A pressure-relief valve prevents an excessive buildup of pressure inside the tank. When hot water is called for at a faucet or appliance, heated water is pumped out the top of the tank and through ...

If you have separate hot and cold valves, the fix is tougher -- you have to replace the valve. We remember the TV program you mentioned. It wasn't "This Old House," it was "Ask This Old House." ...

Water pressure can drop at a kitchen or bathroom faucet for the same reason. But in this case, sediment clogs the holes in a plastic disc and the aerator that creates the uniform flow of water.

Q. I’ve got low water pressure in my house. Is there any way to improve it? My neighbors all seem to have much better pressure, and we’re all on the same city water main out at the ...

You'll often see low water pressure in houses that are located on a hill or very close to a water tower that helps create pressure in a municipal water system. 2. Maybe it's debris or a kink ...
