I have a Kohler toilet. Sometimes it won't flush completely, on the second or third flush it will flush completely, but lets out a big belch. Only the bathroom is on this drain into septic tank. The plumbing was done about 20 years ago and uses an air admittance valve. I tried a new valve, same. I took the valve out and it flushes normal.
I ran a snake into the bathroom sink drain, which goes into the toilet drain to a length where I know it got as far as the septic tank, didn't hit any obstructions and nothing on the end of the snake. I'm not sure what to do next.
Thanks in advance.
