Plumbing question

[Mr.Man]

Don't call Marty the Plumber.  That's for sure.

If you would just drink alcohol during the week, your plumbing would be fine.

Ever consider calling one of those plumber people?  They might know something about something like  this.

If you have a single-valve shower, that's actually a pressure balance valve, not thermostatic, but could potentially be the problem.  If you're not getting enough pressure from your hot line, the valve will make it up with cold water, so it will never warm past a certain point.  If you do have a thermostatic shower, then you have one valve where you set the water's temperature, AND a second (usually smaller) handle that turns the water on and off.  If you do have that, then the cartridge in your valve is bad and isn't calibrating the water temp correctly anymore.

Either way, you need a plumber to get in your valve--usually the cover plate screws onto the rough inside the wall, so it's not too complicated to do that.  Depending on what the problem is though, you may be ordering a small replacement part, or an entirely new valve.  Either way, it's going to help you to know who makes your shower valve & trim (this is assuming it's the shower valve and not the heater, and I'm not a plumber either.  Just sold plumbing for many years).

We have a single shower fixture knob so I guess it's a thermostatic shower. We just had a plumber out last week (home warranty, not insurance. duh) to fix the downstairs shower because it wouldn't turn off.  He probably broke it. Though that wouldn't explain why the upstairs shower is cold, too, if it's a per fixture issue.

Thanks for everyone's wisdom.

Nope, you have a pressure balance shower.  Don't tell a plumber you have a thermostatic shower--he'll start seeing dollar signs before he gets there.

I've considered it. In fact I had one out here 2 weeks ago and while he did fix the shower not turning off problem he horked up the 'cold should be on the right, hot on the left' that wasn't broken. I'll just pretend I'm in Scotland and deal with it.
