I have a 4645 pressure assist Kohler toilet. It flushes but not very well. Water coming from the tank to the bowl is low in pressure. I checked and that water pressure to the tank is 45 psi. is there a adjustment for the amount of water coming out of the pressure tank. And is so how do I adjust so the water comes out with more volume allowing for it to keep up with pressure demands. Thank you

Hi Redsanger

Has the toilet ever worked properly or is this a new issue?

After you answer that I can probably tell you more, but for now, take a metal coat hanger (or similar item) and cut it so you have one end to work with. Now, stick it up inside the jet hole in the toilet bowl (the one the water jets out of)... good chance the hole is getting plugged up and this may clear it out for you.

You don't need to go too far up the hole... maybe 3" max...

Let us know if that helps!
