    My contractor recently installed a Moentrol shower handle ( onto a Moen standard valve using the adapter ( This should work as straight pull-on/push-off, with 90 degrees left being full hot water and 90 degrees right being full cold.

    After the install, I'm barely getting any hot water. Turning left actually gives me freezing cold water, and turning right gives me maybe room temperature at best after waiting 10 minutes. The hot water from my sink is working - it doesn't get super hot, but warm enough when turned on full. I live in an apartment building. Any ideas what may have been wrong? I was searching online and read that maybe the cartridge was reversed, which will cause the flip in hot/cold. But how can I increase the hot water flow?

    Also, the handle is very tight - it takes me two hands and a bit of effort to actually pull the handle on. Will it loosen over time?

    Appreciate any advice!
