    I have a Moen 7400 series kitchen faucet (I believe 7430W). Single lever style handle with attached sprayer. It is leaking at the base of the spout assembly where it meets the sink escutcheon plate. I've looked at the parts explosion on-line and it looks like I may need the "spout O-ring kit" (p/n 96778) http://www.moen.com/shared/pdf/7430pt.pdf

    Do i need to find any other parts to fix this leak?

    Thanks, George

    Replace the o-rings.
    Clean everything and lube with ( I use silicone grease ).
    Clean the diverter.
    Clean and even sand or use a brillo pad on the inside of the spout, wipe it clean and grease the inside where it sits on the post.
    How old is that cartridge?
    Why not change the cartridge while you're there.
    Maybe replace the aerator or at least take it apart and clean it.

    Thanks P1 :) . The cartridge is 6 years old. I'll do as as you say and clean the snot out of everything (and lube). I'll try to look for parts locally tomorrrow. If I can't find them I can always order online. Thanks again.

    I don't know if it applies to Moens, but I've learned the hard way that Delta faucets do best with Delta replacement parts. The generic parts found in some hardware and big box stores just don't work as well or last as long.





  5. You just described DANCO to a tee. I will not use their parts, not even brass stems. Wrap a dollar around them and give them to someone who cares.

    Call 1-800-BUY-MOEN. That faucet is new enough that it should have the lifetime guarantee and Moen should send you the parts you need. Having the part numbers and faucet model will make it easier since they don't have to guess which parts you need.
