Water pressure on the downstream side of the valve pushes up on the diaphragm, when a pressure drop, such as a running faucet occurs, the psi drops and the diaphragm pushes down on the plunger, which opens the valve seat below allowing water to flow through until set pressure is reached, at this pressure there is sufficient force on the diaphragm to push it up and allow the valve to close. -Thats my understanding of it at least
Hope you can help/Short story long/ I have a 1960 ranch, original boiler that works greatAnd hardly any components/Lived in the house for 10 year so far/The first year we lived there there was a main break /After that the. PRV on boiler Goes off at 30 psi and of course the relief valve releases/I have one of those old-fashioned in the rafters expansion Tanks./// my question is the cause of the PSA rising the pressure reducing valve or the expansion tank is waterlogged and how do I check which one it?
Safety relief valve technician here good job that's basically how all safety valves work the screw u adjust tech name is the compression screw.. For future reference anyways u did good for ur first time better than some idiots I know that's worked on valves for years only o e thing I seen that would get rejected always lube those o rings son always.. Lol
The sound I’m hearing in my pipes is a lot like that but at a slower frequency. I CANNOT find a PRV in the house and neither have 2 professional plumbers been able to. I’m not sure if it’s buried in the walls or what. Any tips?
Hmmm. Interesting. The PRV is the first thing when it enters the house, so trace everything as far back as you can. I believe that some houses do not have them, especially if your city pressure isn't too high. I'm not sure, but I assume some tropical or warmer regions would have them outside if it never freezes. Maybe check on that. Maybe you could look into waterhammer, which is a separate issue and makes noise in the pipes. Also, Sometimes pipes can move if brackets are loose or broken and do funny things. Maybe someone else can chime in on a better solution, that's just what I come up with on the top of my head

Yes, thank you, that’s how I understand it too. Thanks for explaining it better
Excellent video as I never knew how those valves worked! Happy Holidays! 👍👍🌲🌲
thanks for watching! it's neat how they work. happy Holidays to you too!

I do not know the first thing about boilers, sorry.

Thanks for the tip, but lube what rings exactly?
Thank you, this is so informative and well presented. Not too slow, not to fast. Every step is covered, even the clean up is great!
Thank you! Glad you liked it 👍🏼
This is quality content. I mean when you cut open the valve to explain how it is put together, Bravo 👏
I appreciate that! Thank you
Great video!! Very informative! I like swish swish swish for the description of the sound of the faulty regulator!!😆
Haha thank you! I told them that they should keep it, that it’s actually soothing!

I used to install city water meter and boxes, we often found the PRV just downstream from the meter! Hoping this is your case!
Thanks man you saved me $400
Hey, You're welcome! Feel free to drop a "super thanks" if you feel up for it.
Mine is the pressure is too low that makes the sound. I just got it replaced by a plumber. PSI between 40 and 80 is good.
Did yours have the plastic sleeve on the adjustment screw? Mine does and do you just snug the lock nut against the plastic?
How activate beast mode in Handyman Hertz. Just say “do you want me to find a cheater bar” 😂
😂 I’m either too stubborn or too lazy to get a cheater bar. Thanks for the laugh.
That water regulator looks like it was installed in the 30's
I believe their home was built in the mid 2000’s.
What brand are those channel lock pliers?
I think they are Knipex. I was using my buddies.
@@HandymanHertz Knipex... thxs.. Found them, they're called a "pliers wrench."
