We have a 'unique' toilet and the bowl doesn't empty completely
Help
We have an older toilet, an old brown one, probably about 25 yrs old. There is an 'extra' tube in it sticking up; it is about 1" in diameter, and is capped off and did seem to leak there after we removed the commode to replace the flooring in the bathroom. We went to Lowes' (the only plumbing source in this small community open on a Sat) and think we replace the gasket on this 'tube'. We cannot see any reson for this tube, it doesan't seem to do anything. Is it a vent? But, we put the commode back and it didn't leak. So we thought we were good, But when you flush it doean't empty completely. It takes 2/3 flushes to empty the bowl.
Why is that, and are we just wasting our time, should we get a new commonde?
I want to try to replace all the guts, since they are old; but my husband isn't sure this is the problem...
And again, not sure if that 'tube' plays into this problem...
Appreciate you advise,
Thanks
