Hot water heater leaking from pipe fitting and it seems top as well


Hi,

I came home last night to a puddle of water on my garage floor. I noticed a drip coming from on of the input pipes leading into the top of the hw heater. I also noticed some drips from the top of the unit as well. On top of that, it seems as though the water pressure in my house has increased which has caused one of the bathroom toilets to not stop running and goes over the overflow unit. Please help me figure out what to do.

Sounds like you are on public water and have a Pressure Reducing Valve that has failed. You may be able to adjust it or you may have to replace it. You will find it on your main water supply line.
Get an inexpensive water pressure gauge from any hardware store and test the water pressure of your home. It will fit on a water hose spigot.
If it is more than 60 psi, adjust or replace your PRV.
Turn the toilet water supply shut-off valve down if you have one, to reduce the pressure there temporarily.
Good Luck!
Mike

Go with Mike's idea first.
You may have a check valve installed witch makes it a closed system. If you do not have an expansion tank on your water heater and it is going bad (thermostat) it will cause your pressure to increase. Does the water seem to be hotter? Temperature increase = pressure increase. Turn the water heater off and see if your problem stops.

I have a private well actually. The water doesn't seem to be getting any hotter than normal. Can I post a picture up here?

You may have a bad pressure switch. Is there a gauge in the system?

Maybe you have a rusted out spot where the inlet pipe screws on to the top of the water heater.

Turn on a hot water faucet (preferably as close to the heater as possible) and let it run for a little while. Does the pressure drop back to "normal"?

Caution: If you should ever see steam spouting from a water faucet or unusual high pressure bursts of water, open the faucet all the way and then turn off the water heater gas or electricity immediately. The heater could have stuck in the on condition and the tank could explode.
