We replaced the dial on our tub yesterday, and the little plastic stem to which the dial attaches was looking chewed up and we wanted to replace that as well. The plumbing dood in Home Depot said that little plastic stem was part of a manufactured piece he called "the cartridge" and it could only be replaced from the other side of the wall, in other words it couldn't be pulled out from the front. Sounds like a big job, so we left it alone, and just superglued the new dial into place to reinforce the attachment. Worked fine.
About an hour ago the whole fucking "cartridge" popped out when I turned on the tub. Clearly the thing does NOT pull out from the back. The little metal ring that screwed over the cartridge we learned was not just decorative, but is the only thing that holds it in place against the water pressure. Now the problem is we trimmed down the plastic pipe the ring screwed into to push the dial further down on the stem as it would fit more securely. We never would've fucked with that thing if dingledick in HD hadn't told us the cartridge can only be removed from the back. Now there's no fucking way to screw on the retainer ring again. WTF!
All we need is some way to secure the cartridge in the pipe so it won't pop out when we turn on the main water line again. I'm sure a plumber would have 3 different cheap and easy ways to do that for which he'd charge $978. Any ideas, PLEEEEEASE!?
