Delta faucet cartridge replacement

Posted by Denis421 (My Page) on

In need of some advice. Facts: Delta shower single lever tub shower faucet in need of cartridge change. Monitor series with temp adjustment dial on handle that controls water volume. Here in lies the problem. The screw in the center of the cartridge stem (under the temp control) has corroded and doesn't have a head (corroded flush). I have purchased trim kit, cartridge, and rough in valve. (in case needed) Is it worth the effort to use a craftsman type screw extractor, drill and attempt to remove old cartride, or should I just replace the whole thing. I would have to go through the tile wall. This is a split level house and the other side of the shower rough in is not accessible. Lastly, any ideas what it would cost to have a plumber do the whole replacement should I decide not to do it myself. Thanks

Drill the screw and spray the screw with PB Blaster and apply light heat (hand held propane torch judiciously applied) to draw the spray into the threads.

Use a flat concrete "cut nail" as an EZ out. The cut nail is soft and will twist (won't snap off like an EZ out) if the screw is stubborn.

May need repeated PB Blaster and heat but they usually come out.

Use a dab of anti-seize on the new screw threads.

I would take a more direct route. Use a screw extractor, predrilling with the bit that comes with it. Working carefully (so as not to break the drill bit) it should still take you no more than 5 minutes.

No reason to replace the whole thing just because of a broken screw.

Justalurker and homebound, thanks for the feed back. I'm going to use the PB blaster (w/judicially applied heat) and then the screw extractor. I'm not sure why Delta didn't make this screw either brass or stainless, unless it was a prevous owner's replacement. Going to tackle this Sunday, I'll leave feedback. BTW, justalurker, I thought cut concrete nails were hard. Perhaps I'm imagining something else. Denis

Just a simple cut nail...

... will twist and not snap.

EZ Outs and screw extractors will snap and not twist.
