Installing a Moen 3570 valve.
I seem to remember from somewhere that you should remove internal parts from a tub/shower valve before putting a torch to it, but I can't figure out how the cartridge comes out. Is there an alternative to trying to find the Moen 104421 special tool?
It looks different from my other special tool
