Explosive water pressure after running hot water


After running the hot water in the sink, shower , or washing machine, I turn off the water, wait a few minutes, turn it back on(hot or cold) and the water pressure is extremely high. I mean it explodes out of the faucet. I'm starting to get dripping faucets. Any idea what may be causing this?

Is it just the hot water side or both? Get yourself a pressure gauge and test it at various points in your house.

Could be a number of things. Have to troubleshoot and see where your problem is. Going to have to ask you more questions. Like dj suggested, you can get a pressure gauge for about 5 or 6 dollars at hd, or lowes and check pressures at various spots in house. Anything over 60psi is getting too high, normal range is around 50-55psi.

However, from what you are saying, it sounds like the problem is throughout your entire house affecting all faucets and water fixtures (both hot & cold, toilets, washing machine, etc.). Is that correct? Also, are you on city or well?

You may have a bad prv (pressure reducing valve) in basement that has gone or is going bad. Quick thing you can check, they are usually located on the incoming water line by your water meter somewhere. Sometimes they are by your hot water heater. You may or may not have one, I don't know. Trace your pipes and see if you have one. If you do, look for signs of leaking, scale build-up, etc. Post some pics of it. If you have one, it will look something like this: Click on link below.

It sounds like your HWH thermostat is not working. This kind of thing also happens when you have air in the lines. Is the hot water extremely hot?

I suggest you turn off the hot water tank and call a professional. Sounds like your tank my be over heating the water. It looks like your Temperature pressure relief valve on your tank may not be working. An exploding HWT with super heated steam can level your house. I hope this reaches you in time.

He did not give enough information for a good picture. Regardless it is always wise to kill the tank if your not sure.
