I have a circa 1970-71 condo with a Moen Bath-Sh0wer valve with a built in diverter. I assume this is the 2400 series. Being 50 years old, I'm not sure when the cartridge was last replaced, and the spool if ever.
In cleaning this up, I did put in a new diverter (amazing what it is supposed to do if not stuck), and considered replacing the cartridge and spool as well. The problem, of course, is shutting off the hot and cold water - something that was not required for the diverter.
With some effort, I was able to unfreeze the hot water stop check valve entirely. This required multiple turns to the right, after which the water did turn off. The cold however, although there were multiple turns, did not turn off. I do understand that are some check/shutoff valves that only take a 90 degree turn; these clearly are not that variety.
My questions are:
1. Have I just not turned the screw enough times (and there is some residual crud left)? (And how many turns is it supposed to take?) (After getting the valves open and closed, at least part way, I was quite surprised at the amount of white, gray and black particulate matter got flushed out...)
2. What is the part number for this of a check/shutoff valve of this vintage? (Is this a 12318?)
3. Am I looking at needing to replace the check/shut-off valve (which mean turning of the water to my entire condo stack).
Obviously, I'm not going to attempt a cartridge/spool swap if there is any chance the cold shutoff is "marginal".
Thanks in advance for thoughts.
