Why Are My Pipes Banging?!? | Pressure Reducing Valve Installation & Adjustment!

- Most everyone has had the agonizing experience of showering under the anemic trickle of water resulting from a building's low water pressure. No fun whatsoever.
But can there be such a thing as TOO MUCH water pressure?
If your water lines rumble like freight train or sound as if someone's hitting them with a sledgehammer, whenever you open and shut a faucet or flush the toilet, then it's very likely that you're the victim of excessive incoming water pressure! Aside from the obvious nuisance that high water pressure may cause, the continual shock inflicted upon your pipes and fixtures can quite literally be DAMAGING to your entire plumbing system!
The good news is that there is a solution to help 'ease the pressure' (and the headaches from all that noise!). And that solution is called a called a 'Pressure Reducing Valve' (or PRV for short), which allows you to reduce the incoming building's water pressure to a safe and desired amount.
Today we'll be installing and adjusting a Watts PRV model LF25AUB-Z3…and it's not as complicated as it may sound, although there is a proper way to do it so that it's effective. With the guidance of this video, I'm going to show you how!
Goodbye banging pipes!!!

Great video, can you make one about Water Hammer Arrestors? I see that there are all kinds of types available some have adjustable pressure (via a Schrader valve) others are not.
Thanks
Thank you once again! Funny that you mention water hammer arrestors. While making this video they came to mind as a video idea as well, since they're very effective at preventing water hammer. You mention arrestors with Schrader valves...I'm wondering whether you're actually referring to expansion/bladder tanks, which essentially perform the same function as arrestors although they're constructed differently.
In any event, I do have another video idea lined up for that as well, particularly in reference to thermal expansion.
I've formally logged your request and will look more into the arrestors you mentioned. (NOTE that I haven't forgotten about your request for slope and grade from back in July...unfortunately, time is my greatest liability!)
Thanks again for your feedback and support! 🙏
@@PlumbingsCool You got good memory about my P-Trap Arm Question! 😀
The arrestor with the Schrader valve is a LF150A Water Hammer Arrestor by Watts.
I wonder if they have any benefits vs non-adjustable ones?
I presume that the Schrader valve is a weak point since the air pressure always leaks eventually vs the pre-charged units?
Thanks...I'll be sure to look into that Watts model you mentioned!
Is there a reason why a person shouldn't use a ball valve adapted with a hose fitting instead of a hose bib? It would be used for a different application.
Thanks for the parts list. 👍🍻
Technically, you can use a ball valve and adapt to a 3/4" male hose outlet. As a matter of fact, there are ball valves that already have the hose thread built-in:
www.dahlvalve.com/products/mini-ball-valves/hose-boiler-drain/iron/hose-boiler-drain-621-01-04-PK2.php
as much as I'm a personal fan of ball valves, there are a few things to consider. First, because a ball valve is full on/full off across a short quarter-turn of the handle, you have significantly less throttling control than you do with a standard hose bib. Also, the ball valve's handle also makes it very easy to accidentally knock it open when passing by - causing a potential mess. Aside from these discrepancies, ball valves are by far my favorite valves.
One thing I didn't show in this video is that I also supplied and hand-tightened a female hose threaded brass cap onto the hose bib, to prevent any inadvertent messes in the event the hose bib is turned on accidentally. You can easily find these relatively inexpensive caps at local plumbing suppliers, big box stores, or even online:

Hope this helps, and thanks for watching! 🙏
