Looks like my valve on the toilet cracked last winter it a 2018 TAB I see a lot of different numbers and wondering what is the correct one. I've been looking on Amazon. Also I guess I should get a new gasket.

thanks I did find that but the valve number doesn't match the toilet number. I'm not real sharp when it come to this but I know I can change it

How do you get to the valves in the back of the toilet?  Can I remove the entire seat to replace the valve?

@Carriehb, which Tab do you have?

For the "320" you'll need to take the toilet out to work on the valve.

Turn off the pump, depressurize the water lines, disconnect the water supply behind the toilet, and then pulling the toilet is easy. Two nuts on the floor. The toilet flange gasket seal is rubber (as opposed to wax), so comes out 'clean'.

Depending on the age of the seal, it probably can be reused, but replacing it too, might be smart. Check to see if the seal comes with the valve as a kit.
