Hello everyone, I have a rental property I have been working on and have a problem with the toilet. When the fella who was living there moved out he said that the toilet was not flushing properly, he was right. It would swirl very weakly and every now and then it would barely flush all the way. It was old and ugly so I opted to just get a new one. I bought a good brand name, glazed trapway toilet and installed it. Everything goes down fairly decent but as soon as you hit that flush lever a large bubble bursts up and sometimes splashed up on the seat. The air seems to come from the small hole at the bottom on the front side.
I recently had the clay pipe main line cleaned out and can stick a garden hose into the clean out in the yard and push it to the point to where it should be reaching the sewer. I got up on the roof and stuck the hose in the vent and can see it go past the main line clean out in the front yard. Everything seems to be unobstructed, even the pipe under the toilet is clear. Even though everything seems to go down fairly decent could there be something between the main line and the pipe under the toilet (the part you can't see)?
Any suggestions? Bad toilet maybe?
It may not matter but before I took off the original toilet I replaced the water supply valve behind the toilet, it was bad but didn't help the initial problem very much.
Thanks in advance.

Good morning Scott,

Ordinarily when a toilet "belches" it's a sign of a partial clog downstream of the toilet but I don't think so in this case. With a clog the "bubble" comes back through the trap but in this case it is forced through the jet hole.
This indicates that the air trapped between the tank on top and the trap in the bottom is being pushed out as a "belch" through the jet when flushed. This is not normal and I would attempt to get the store to replace the bowl, (you don't need a new tank) under warranty. Good luck, Tom

Could this also be the seal between the tank and the stool?

I agree with Tom. It is probably toilet design that causes it to splash... What brand / model of toilet did you get ??

It should have nothing to do with the wax ring. If the wax ring was the problem then it would leak around the base when toilet is flushed or it would be sluggish in emptying water from the bowl...
