Shower Cartridge & Regulator Valve

[cbrunny]

What's the difference?

We have a mixing valve on our hot water tank that mixes hot and cold to produce non-scalding water. This was replaced yesterday because we were having issues with the hot water in the house. It has resolved the problem.

Except the shower. Still not getting hot. Warm, yes, but not hot, and nowhere near the temps of other faucets.

The cartridge in the shower has been replaced as well. The plumber says there is a regulator valve in the shower that probably needs to be replaced.

Is this making any sense? I know basically nothing about plumbing but want to be sure he isn't just screwing me out of another ~$300+.

Take the cover off and see if you can adjust it, it should be as simple as that.

 

[mizzou]

It could yes, it kind of depends on how your hot/cold lines feed into the shower assembly

what do you have?

 

[cbrunny]

Uh. I have.. no idea.

What should/could I have?

If you have a single valve shower there is an anti-scald adjustment that you should be able to make. Given you lowered the temp of your hot water it could be this adjustment is set too low.

Also, that same anti-scalding feature has moving parts in it that can go bad, get jammed up.

 

[NutBucket]

Isn't that just part of the mixing valve/cartridge? If that's already been replaced....maybe it already got jammed up somehow?

 

[skyking]

Not sure about that. I thought it sat upstream of the mixing valve.
