Product review (5 stars): Replace the hose too
replace the hose.
when I got this I was just going to replace the mechanical part
figured the hose doesn't wear out.  bout half way done found small hole
in original hose, where it had been wearing on the drum.
Water wasn't leaking out of the hose but hole in hose allows drum to overfill.
I replaced both pieces, probably only needed hose.
