When sink faucet on shower water pressure returns
Hi everyone. Looking for help on returning hot water pressure to my shower. I've replaced cartridge and verified that there is no clog at masterbath shower. I was able to do this by turning on masterbath faucet and seeing that full hot water pressure was returned to shower. Also the faucet handle to shut off/pressure pipe is leaking substantially. This handle supplies only this masterbath. Any troubleshooting ideas would be greatly appreciated. :confused:
No water pressure unless sink faucet on
Thanks Tom very much. I'm referring to one shower located in masterbath (mb). All of other faucets/fixtures in the mb bath have water and have normal pressure (no issues here).
The mb shower has only a trickle of hot water unless the sink faucet is turned on. I discovered this after replacing the cartridge because of a first issue which was that the mb shower did not have hot water pressure. I then thought it was the cartridge and removed old and installed new. (Moen 1222) Once new was installed pressure did not change.
It was on a hunch that I discovered I gain water pressure to the mb shower when I turned on mb sink faucet. When the cartridge was completely removed I tested pressure/flow to see and it was good. Only after old cartridge on and new cartridge in did the mb shower pressure drop to a trickle. Thanks.
When sinck faucet on shower
LOL here! I can't believe I stumped YOU :D ! Now I don't feel so dumb.
After some more troubleshooting this morning I resolved the shower and it is working.
First of all I still don't know why turning the sink faucet on added more pressure to the shower. I did figure out the because the cartridge was a moen with the posi-temp that I had to set the temp with the new cartridge. Previously I skipped this step in the directions. When I went back over directions I was able to get the correct water flow and temp. Shower fixed.\
Thanks for helping me. Plumbing is a lot of deductive reasoning and patience.
