I have an issue with my shower valve.........the hot water works fine, but the cold is a trickle.
I KNOW what the issue is..........it is debris from the installation of saw cut plastic pipe in the house.....blocking or otherwise screwing up the valve.
So I figure I'll fix it. The handle came off easily (this is a one handle type unit).
Underneath is a semi-spherical piece that appears as if it "screws" on or off.........holding in the valve cartridge. It is knurled at the base; a further indication that this thing screws on/off.
BUT..........it won't budge.....even under a pretty good attempt with channel locks.
I heated it as much as I dare with a torch.........no dice.
Anyone have any experience with this type of piece of crap?
