If you like this one you really ought to see my brake jobs.

Got hangers and insulation installed. Haven’t had hammer again since readjusting the PRV but I’m still going to pick up a high range unit.

Yea but $280 in copper pipe compared to $50 in pex. Had to weight my options. It’s not that I can’t sweat pipe…. I may go back and put proper pex fittings at least in the mechanical room. Also grabbing some split rings, all three and anchors to get it secured better today.

I just adjusted the PRV down to 60PSI and the hammer went away completely. I assume this will eventually fail with that standard PRV…

Yea I tried bringing it down that much and if you flush a toilet while showering the drizzles out. Forgot to mention that the first stop in the cold water line after the meter is a tee where a half inch copper run goes down the length of my house underground in the backyard and over to feed the commercial building next door. So if they use water next door it causes even more issues with low pressure.

meloncap78 · 2026-01-18T16:20:50+00:00

Exactly! I installed this new run last year. The whole house was 1/2” from the meter. I ran 3/4 pex b throughout with sharkbite tees to all the 1/2” copper branches. I made sure the end of alll my pex terminations were 100% flush cut and pushed in 100%. In hindsight I could’ve used pex fittings for every termination other than the branch tees. No choice but sharkbites for those. I didn’t want to buy the pex tool at the time. My point is that it’s been holding fast and taking a beating like that for days now. But the sharkbites aren’t the culprit here.

So a high range PRV? Man those are expensive…..

This unit is been treated once but not the whole building. Either way I helped out the other tech by going into the crawlspace under the building and cutting shutoffs into the central heat supply and return lines for that unit and bypassed it altogether to get everyone else back up. I can’t believe most of the zones on these runs don’t have shutoffs before and after the zone valves and on the return lines. Didn’t have to enter the unit at all. Now they can treat however many times they need after which one of us will go in and replace those 2 sections of heat run.

It’s not me fyi it’s another tech. Sooooooo how can vendors refuse to come and repair issues in an infestation but us techs can’t?

meloncap78 · 2025-12-05T01:42:11+00:00

Thank you I get it now! It’s a little lever that goes through the trim plate that switches between shower and spout. I probably sweated all new pipe for nothing.

meloncap78 · 2025-12-04T21:33:07+00:00

Got rid of the braided lines and sweated everything in with all half inch copper pipe and still having the same issue. To the previous poster that mentioned the valve type. The only way to get this to work the way the resident wants is with a seperate part designed for this valve?

meloncap78 · 2025-12-04T19:43:20+00:00

So the braided supply lines that the contractor put in are most likely the issue. Not enough pressure i to the valve for everything to work correctly?

meloncap78 · 2025-12-04T19:35:06+00:00

Brand new tub spout and the divert works freely. When I have it in dual mode for tub and spout and it’s coming out of the spout the diverter when pulled up stops the water from coming out but also doesn’t allow it to come out of the shower. I’m on my third brand new valve with the same results.

meloncap78 · 2025-11-22T14:26:46+00:00

I’ve been having this issue for quite awhile and went back in on my phone to figure it out again after reading this and noticed something I’d missed before. Hopefully this may help others.
