I recently purchased a Moen 7730 W faucet (July 2001). I have it installed but have a problem. After the faucet is shut off, the water continues to drip slowly and a glass a night accumulates. All connections are tight and there are no leaks underneath the sink. I am not sure what to do? The cartridge should not be bad as it is a new product.
Help for a cluless plumber want to be in Texas greatly appreciated!
