I have a shower which will only output cold and warm water. It will not output hot water.
Single Handle.
Valve is a Pfister 0X8-010A style.
Copper piping.
I have two other showers in my home with the exact same setup/valves. These showers work fine as do the other tubs and sinks. The sinks and tub in the bathroom with the problematic shower are working fine (good hot water). Note that my in my home, the showers and tubs are separate.
Here is what I've done so far (with no success).
1. Disassembled the valved. Inspected for buildup, and debris. Everything looks clean and new.
2. Completely swapped the water mixer/valve (cartridge) and handle with another shower which is working properly.
3. Swapped the rubber gromets with another working shower valve.
4. Removed/inspected shower head (still get warm water only with spray head removed).
5. Removed the temperature control ring. (Best I can tell, by removing it, you get full control of the valve)
The design of the hot/cold water mixer is pretty simple. A plate with two tear-drop cutouts which backs up to the rubber gromets inside the hot and cold water lines.. I'm certain that I'm getting full valve control (full cold.... and full hot water at each ends of the valve/handle).
At this point, I feel I've eliminated the valve and mixing unit.
I've read in forums that say I should flush the line (rational is that debris is in the hot water line, behind the valve). But if there is a blockage of some sort, I'd expect to see significant lower hot water pressure... and would still get hot water when the valve is on full hot....tho maybe the mixer is doing something I don't understand. Note that I do observe a slight drop in water pressure when the valve is set to full hot.
Question1 : Any hints on how to flush the system w/o creating a dramatic mess? I'm thinking I'll find a buddy, turn off the water, remove the mixer and gromets, hold a bucket in front of the exposed lines, turn on the water for a minute or so, waterworks galore, turn off water, look for debris on the shower floor, and reassemble. Make sense?
Question2 :Any other tips or advise appreciated. I'm running out of things to try.
Thanks in advance.
