Pressure Relief Valve Leaking

Hello

I changed my pressure relief valve yesterday because the my pressure guage was indicating that the pressure was not being kept. When I replaced the relief valve, water continues to consistently spill. The spill is not a little, but a lot of hot water. What am I missing? Because of this I am not getting hot water or enough hot water to the house and also is affecting my heating. Please need urgent help.

Is this from your boiler or HWH?

Please post make and models...

Its either too much water in the boiler from a faulty fill valve or a faulty expansion tank... ( If boiler).

Can you post pictures?

Oh and welcome to the forums...

Hey Lawrosa

I don't know much about this stuff, but I would have to say the hot water heater (not the 40 gallon tank). The Make is Williamson, Model - GWI - 063N-1

Just a brief history, I had a similar issue 1 yr ago and replaced the pressure relief valve. It worked with some spillage (sometime a constant stream and other times just dripping), which I could have lived with. When I noticed the similar signs yesterday, I immediately thought of that being the issue. When I removed it, there were a lot of gunk in the valve and after cleaning it, I tested it with water. No suprise, the water leaked right out.

I placed a new valve last night, but its spitting out even more. What am i missing and what could be causing the issue.

Thanks for any insight.

I also purchased a cleaning fluid from home depot to place into the boiler to get the gunk out. i poured that in last night as well.

The issue is occurring on the boiler - as stated in my original post.

Thank You

First step is to service the expansion tank.. Thats the most probably cause...

Did you read that link?

What does the pressure and temp gauge read on the boiler???

It that's over your head then it's time to get out the phone book and make some phone calls.

I actually figured out the issue. The fill regulator is faulty causing water to continuously feed the boiler. This is causing the relief valve to constantly release. I am in the process of testing the expansion tank, but would most likely replace it... but thanks for the help

So with a little effort you realized that it's NOT over your head, didn't you?

As long as you do due diligence and keep your eye on the pressure gauge to make sure it doesn't go too low, there's no reason why you can't put off replacing it until the spring.

Heating system is CLOSED and should not lose water. (if it does, it indicates a slow leak somewhere)

You would most likely be fine if you pressurized the system to 12-15 PSI when the boiler is COLD and CLOSE THE MANUAL SHUTOFF valve.

It is perfectly OK to run the boiler with that valve closed.

AS LONG AS YOU KEEP YOUR EYE ON THE GAUGE!
