Remove the aerator off of the faucet.
It may have "antifreeze" goo in the screen.
The 7400 uses the 1225B cartridge
This 4 year old faucet is in our RV.
it has suddenly drastically reduced the amount of water coming thru the hot and cold sides.
thinking of replacing a cartridge -if it has one.
yes i went to the moen site - could not find it.
we had to have pink antifreeze (non toxic) put in the water lines over the winter. when we removed the pink stuff it worked fine. a few minutes later this - maybe a blockage.
how do i get it apart to fix it so i can go south for the winter!
PS all the other taps/faucets run fine.
