I just replaced this valve and now I have an intermittent leak from the showerhead. I was dripping approximately once an hour, but it now it seems to be increasing in frequency. Could I have nicked one of the seals when installing it? I'm not sure what to try other then picking up another one and seeing if I have the same issue...is this a common problem?
When you replaced this you need to flush out and debris before you reinstall. Did you install a genuine moen cartridge. was it brass or plastic. Make sure it is also in the right position when you reinstall and put handle back on.
Thanks for the reply. I honestly can't remember if it was an actual moen. I think it was another brand, but made for moen. It was all brass and I did flush it out. What it the difference between the 1200 and the 1225?
