Replacing Delta Shower Cartridge
[B]Good AFternoon, I am replacing a 13 year old Delta shower cartridge and I am at the point of removing the cupling holding the old cartridge on. The directions state to "unscrew" the cupling and remove it and then pry out the old cartridge. I have tried to uunscrew the brass cupling but when I attempt this, the pipe that the cartridge sits in moves to the left. Its as if its sodierd on. Before I break this pipe, I thought I would seed guidance from a professional. Am I supposed to be using a cartridge puller? Or just use a pipe wrench and turn a little harder? Thank you in advance.B]
