Plumbing – Installing new Moen valve not working

Moentrol is the type of valve, the single knob that pulls out and pushes in for flow control and rotates right and left for temperature control. There were numerous trim styles offered with that valve type, so just saying "Moentrol" does not adequately describe your needs. Some of the old trim plates were marked with the word Moentrol, but many were not. If you contact www.lasco.net they will direct you to a dealer. They have a huge line of plated trim in all finishes (ask for the Simpatico line) at reasonable prices and of good quality.They call it Satin Nickel but it looks like brushed nickel. You might need to take your old trim to the dealer to ensure proper size/type, rather than risking an on-line purchase.

Is the leak at the faucet or the cartridge (handle)? If the leak is at the faucet you may have shaken the seats loose or broke gunk in the pipe loose that got into the seats. Both involve turning off the water and pulling the cartridge and looking for damage or debris. If the leak is at the handle you may have cracked the plastic pivot / seal. With a new faucet they may replace it as long as there are no drill holes or gouges.
