I assume you mean the separate H/C valve body as opposed to single handle(bath/shower).

There is one O ring just below threads of body.

Your focus indicates a sewer issue and not a drain issue.
The first challenge is to determine which branch leg of the sewer is the issue and then assess where all your access ports are. Sometimes an outside access port has been covered over by dirt/mulch etc.
If you know where the blockage is ... then as mentioned by other contributors ... you will need a snake. They can be hand driven or motor driven. For great access to the blockage you may need to remove the closest toilet, since snaking through the lower S trap of the toilet really inhibits the snake's effectiveness. Depending on how your house is built ... the roof sewer vent pipes can be a good access point (and sometimes that is where the debris has gotten into your sewer if you have overhanging trees). I have had success with running a garden house up to the roof and down through the vent pipe. You need to have a second person watching by the the toilet to make sure it does not back flow on to the floor. You can get hose spray attachments which help propel the hose and add turbulence to break the blockage ... but I have never tried them.
If your blockage is recurring over the seasons ... and if you have a number of trees close to your sewer line outside then you can have tree root intrusion into the sewer. In that case you need a professional with a special snake that actually has cutting capability to remove the roots.
Attached are 3 photos ... manual snake, motor snake, hose spray nozzle
Good luck with your troubleshooting!

Only if you don't mind having to replace the valve after you finish forcing it with pliers.

Should be a pretty easy fix, you need to remove the faceplate for the faucet then there should be a gap between the wall in the faucet valve and you should be able to see two screws that are holding it on to the wood stud in the wall, you can remove the screws and put a couple washes behind the valve that way it will bring it out further and you should be able to get your handle on it without a problem.

If this is a tub/ shower valve, you installed the cart. upside down. Reversing it should solve the problem. You might have put it in according to instructions but the hot and cold might have been reversed when the valve was plumbed in.

The bottom half of the handle spins CCW to losses the handle from the body. You can then tighten the screw inside the handle.

There is normally a tag on one of the supply lines.

It takes new valve cartridges and sometime complete valve bodies. Call Kohler, it should be covered by their lifetime warranty. They are very good about service.
