Old catridge plumber took out 2 years ago and he left me a new one too.
(A plumber changed both hot and cold ones when only cold one leaked probably 2 years ago but hot water side drips occasionally now. There may be sand from hot water heater. Time to flush the catridge if I can take it out)
catridge holder and extender
faucet
7/8" (or 22mm) hex Husky deep socket can drive the catridge but it is too large to go in the catridge holder.
