The mystery of the pressure balancer

Hey Gang,

Maybe some of you super sleuths can help me solve this one. I could go into more detail, but I will keep it short for now just in case it's something simple.

I have a shower that continually drifts toward cold. I installed a new valve, same problem. I replaced the PB several times, same problem.

The other two showers in the house do not have this problem.

Sounds to me like it's not the PB. Or are they just made that poorly that you need to install 10 of them to find one that works?

The new valve is American Standard. The old one was a Delta.

Any ideas?

Nothing? Not even any guesses?

You may have the hot limit set too low, increase the amount of hot water following the attached instructions. You have to remove the handle and adjust the gear located underneath. Increase the amount of hot water being allowed into the mixing valve.

If that doesn't work, remove the cartridge and check for debris. Possible that some solder got dislodged during installation and is stuck in the valve. This usually results in a leak, but worth a try if the above adjustment doesn't result in success.

You know, I'm pretty sure I already did hot limit, but after looking at it again, maybe I set it in the wrong direction. I will pull it off and double check.

Thanks!

Yeah, as I recall, it goes against what your brain tells you in that you set it to lower numbers to increase the amount of hot water. It is spelled out on page 2 of the instructions previously attached.

Also what type of HWH? Tankless? If so the scald control plays havoc at times...

Yeah, I was right. I had it set at "0". So I changed it to 3 just to see what would happen. I'll find out tomorrow.

FYI, it's a standard 50 gal gas heater.

Completely forgot to post yesterday.

With the stop set to 3, I had the expected results of having less handle adjustment on the hot side. But no affect on the temp drifting.

Is it possible to just disable the balancer?
