For the plumbers out there, I'm trying to remove this cartridge

Looks like you already removed the threaded collar. On my valve, once collar is removed you should pull & wiggle simultaneously. This did not work for me and mine split in two parts. I put it back together and will work on it later. >>1048480

Fuck me m8. Yeah I already removed the collar and such and it was a straight forward pull out. But upon inspection of the cartridge, the metal, plastic, and rubber rings were all still in-tack. I wasted $16 on a seat wrench to find out there's no seat, and water kept draining out of the pipe even though I already shut off my house's main water supply and depressurized the system.

I'm almost certain it has to do with the piping behind the shower controls, that I'd have to cut out the tile and remove it to attend to

sometimes the replacement cartridge comes with a 'wrench' to remove the old cartridge. usually just needs a good jerk to break it loose then it should come out without much trouble.

Get a shop vac and suck all the water out of the pipe.

It keeps flowing regardless. If I take my finger and plug the pipe, the water rushes back down into the bathtub spout. The main problem is that the spout leaks hot water, which I would think would be the hot water cartridge. Should I just replace the cartridge anyway since it appears to be fine?

seems like your main shut off doesn't completely shut off the water. is there another shut off near the street that the city controls? when I needed to replace a gasket in a union that was in line in front of my in-house main shut off valve I needed to call the city and have them shut off the water from the street.

>I'm thinking this is a delta shower cartridge.
It doesn't look like a Delta.
It looks more like a Moen>>1048501

It's probably not.
Just pay the $10 for a new Moen cartridge - it's leaking because the internal parts are worn.

Just an fyi, you HAVE to use the same cartridge for the type of valve. I bought a house, shower wouldn't work, so I pulled out the valve. The only thing I could find online for the valve was like $50 fucking dollars plus shipping from China because the people who remodded the upstairs bath used a shit contractor, so I tried to use a cartridge that was the same diameter but shorter. I jammed some rubber O-rings in there behind the cartridge, but you can't turn the water off from the cartridge that way. It was just spraying water everywhere. I'm now currently ripping that whole shower apart because it's ugly and I want to put a shower/bath in there anyway, but I'm going to have to put a whole new valve in there since I can't go to <insert home improvement store here> to find the cart for it. I literally can't find that cart in a store in a 50 mile radius from me and I'm not driving any further for that.

What room is behind the shower (tub)? Sometimes it's easier to cut an access hole in the sheet rock if you have to access the pipes or replace the valve. Then you can install a nice access door for future repairs.
