yes! I thought this was it but to be sure I searched it and found a picture of it on another post, it is exactly the one! on that post they had a link which I used to find this whole rebuild kit, do you think I need the whole thing or just replace the cartridge and handle? The plumber said it was the handle that was causing the hot water issue, he was there for a toilet issue and had to research what brand this was ( and I have not heard back). I am so impressed with this site and help I received! Thanks!
