Okay, first - I replaced the Taco hot water recirculating cartridge. Pretty easy albeit expensive part. The original cartridge didn't have ANY fins left. Basically spinning w/out moving any water. I had a few fin chips in the pump but I'm guessing everything else is in the water heater.


Help! I replaced the Moen shower faucet cartridge (single lever Posi-Temp type). The previous cartridge was working but at a lower temperature.

I think I installed the new cartridge correctly - seated well, no leakage, HC on top (just like before).

But when the lever is in the Off position, water is flowing. It gets hotter as I turn the lever counter clockwise until about 12:00 when the water shuts off. Then turning the lever some more will allow water to flow again (cold) until the lever is at the (normally full hot) 9:00 position.

Help - what did I do wrong? How do I fix? Or is the cartridge faulty? I'm going to try to search for this but if anyone can help more quickly, appreciated!

Never mind. Found it. Figured it out and fixed.

Apparently there is a bevel on one side of the cartridge knob and it needs to be facing down when I install the parts back.
