Hi guys,
I just finished replacing a PosiTemp 1222 in the shower and it was a colossal PITA but ended in success. I thought I'd share some things and I have a question for the professionals.
First let me say that of all the information that I viewed prior to tackling the job, the discussions here were by far the most useful. Since I am an engineer I went into the job with a handicap (the professionals are chuckling because they know what I mean) and I was under some pressure from wifey to get the thing fixed, but I had to do it quickly as my son, his wife and my newborn grandson have been here quarantining and I didn't want the water shut off for long.
I bought the 1222 cart, some Danco faucet grease and a puller from Lowes for $62 with my veterans discount. I had taps, easy-outs, bolts and washers on hand just in case.
The cart turned 45º easily and then with the puller installed started coming out about a quarter inch. At that point I figured that "this is a piece of cake". Well, it wasn't cake after that. Basically it took two of us twisting, pulling and cursing to get the thing out. I am just glad it didn't break off in there. After it was free it left small pieces of rubber stuck inside the chamber and luckily my son's 27 YO eyes were able to help him get them out with a needlenose and some hooks.
The rest went easy except the clip (old, flat style) did not want to go back in and then I remembered someone saying that a nudge at the end of each prong can help it find its way.
So, my question for the professionals is how much would a plumber have charged to replace this cartridge? I imagine they would have an ONA (Lasco) puller, which would have made this easy, but I didn't want to invest in one.
