Boiler Pressure Relief Valve Replacement

[@michaellabonte1260]

I am going to change the relief valve on my Weil-McLain boiler. Your video is great in that you don’t waste the viewers time, you just get it done!

[@patrickmcglinsky1433]

Fantastic video! Effective and right to the point. I have this exact problem on this same boiler and will be replacing the relief valve and expansion tank tomorrow (for my first time). Thanks for demonstrating that it should be as straightforward as I had hoped.

[@NYCLowrider]

Nice! I have the exact boiler and that valve fills up a bucket of water every week and a half... I already changed the expansion tank too! Time to change the valve.

[@diablom3]

Did that fix your problem?

[@Brian-zg2ov]

You the man. This was a perfect video for a DYI guy. Thanks for saving me $$$

[@SevenFortyOne]

I'm always happy to hear about people saving money. Glad this helped!

[@jamesruane382]

Thanks. I’ve got a 40 year old WM boiler and I want to keep it running

[@spinfunky]

Great tutorial video. I have a leaky valve on a fairly new system (about 4 years old), so likely just a valve.

[@joycefortin7877]

I see a tag on the valve on my boiler state that a licensed plumber must be the one to replace this valve in compliance with code. What is your opinion about that? and I see there is a tag on the one you are changing too. What do I do about that? Thanks

[@SevenFortyOne]

You should have a licensed plumber do the work.

[@MadDogClyde741]

Hey 741 ! Do you have to purge the zones after draining the boiler and changing the relief valve ? 🤷‍♂️ Great video but I just wanna be sure 👍🏻

[@SevenFortyOne]

You should check with an HVAC guy...it might not be necessary but probably won't hurt

[@James_Bowie]

Did you check the expansion tank?

[@SevenFortyOne]

Yes...it was fine I left that clip out of the video to keep it short. I really thought it was bad too but it wasn't

[@paulagenasevich9266]

Thank you! Easy peasy!!👍

[@SevenFortyOne]

Glad this helped!

[@johndonlevyjr8776]

Is it really necessary to drain the boiler? What would happen if I didn’t?

[@SevenFortyOne]

I drained mine so I could correctly check the pressure in the expansion tank.

[@fred70flintstone]

You would be wearing 180F water 12 to 20lbs

[@Radiowild]

I had the same problem. I replaced my valve. Ultimately, draining my expansion tank solved the problem. There was nothing wrong with it. It just became full and water had nowhere to go except the boiler.

[@SevenFortyOne]

I thought my tank was bad too, but when I checked it was fine. No water in it and set to the right pressure.

[@Radiowild]

@@SevenFortyOne I replaced the pressure regulator a few years ago, but forgot to drain the tank. This is the regulator that goes to the inlet of the boiler. The following year, my pressure relief valve opened up. That when I remembered that I never drained the expansion tank.

[@VinylSpotlight77]

What state are you from and what trade are u in?

[@SevenFortyOne]

CT. Electronics manufacturing

[@vancegillenwater9609]

I wish you had left in the part about checking your expansion tank😢

[@hamrad88]

Thumbs up.

[@Skyluke104]

Hey Brother, I just replaced my expansion tank that went bad and after awhile it was working but it started to leak water at the pressure relief valve. It's losing pressure the heat won't go up to 2nd floor of my house. I usually set 12-15 psi of pressure but it goes down to zero after awhile. My question is how many minutes do I need to cool off the Boiler after shutting it off and do I have to bleed to drain all water before starting to work on it? Usually what size is that pressure valve 3/4? or 1/2. Thanks for your info .

[@maxwellschaphorst8574]

I know that pressure valve is usually 3/4". It should say either on the PRV itself or a tag on it, but on my Gold McClain its 3/4"

[@bruceberger1569]

Mine 3/4”

[@bruceberger1569]

Actually , what your calling a coupler is actually a brass called a BRASS NIPPLE always clean pipes to be connected & FLUX MALE PIPING BEFORE SOLDERING , otherwise 👍👍👍

An easy fix now save you a big mess and a worse fix later

[@willsrestorations]

It's not called the coupler it's called a nipple. As a plumber you should know that

[@SevenFortyOne]

I'm not a plumber

[@willsrestorations]

@@brandoncooke7223 a nipple and a copper or two major differences, but what would you know you probably work for Walmart as a greater or receive checker.

[@SevenFortyOne]

Greeter and greater are two different things as well. You don't seem to know that so I'd say we are even.
