We had a dripping showerhead that was driving me crazy! First we tried replacing the shower head, that didn't fix the problem. Then we replaced the cartridge, bonnet, water temp handle, and the knob that turns the shower on. No leaks, so we are on the right track. This was a Mixit faucet, which is now made by Danco. The problem is, the temp. control handle moves much too freely! Even turning the water on or off moves the handle from freezing to scalding hot. We got conflicting directions from the manufacturer and the hardwarw store on the orientation of the cartridge? Can it be just rotating 180 degrees will fix the problem?
