Wink Toilet Bubbles after flush

I have recently installed a new toilet in 2nd bathroom, toilet wasn't flushing, would only fill with water. I was told to replace toilet and I did. Now new problem is that after it flushes it bubbles. Ranch house with 2 bathrooms and is septic system. Septic was pumped about about 6 weeks ago. Flushed out vent on top of roof with water hose and all lines have been snaked. Is this something that will go away or get worse? Can I just leave it alone?

Is there another vent on the side of the house? Sometimes you can see toilet paper being pushed out if the trap isn't totally clear.

No other vent on side of house, just the one on top of house. Both Bathrooms have only one vent each.

What brand toilet did you buy?

I am not sure and am still thinking, but it is a possibility that the new toilet is defective.

I will keep thinking

If 'everything' was snaked and vent clear, and septic pumped - then lines are not problem if indeed someone did not miss an area.

The old toilet and new toilet problems may stem from same cause - or may not. They invented the word "coincidence", for cases like this.

If problems ARE related with each toilet, see sentence one. Or you have kids who repeatedly sneak in bathroom and put things in toilet. Or whoever installs toilets there is doing a bad job setting the toilet and wax is squirting down into the hole, and partly restricting the syphon effect.

Pulling toilets goes pretty fast and not that big a hassle. You could pull the toilet (obviously the wax misalignment theory would then be noticed if that were the case), take it outside and set it on blocks (not covering the hole, of course). Fill the tank with water to normal fill line. Then have 5 gallon pail of water or hose next to open tank. Then flush the toilet (If you do this outside, you could sit on it and have someone take your picture for a good laugh. ). Then as the toilet is being flushed, continue to reinact a normal toilet operation by pouring in water in the tank, simulating the fill valve letting in water.

Then see if the toilet flushes normal. If not, it is something about your toilet. If it does flush normal, then you will have to recheck the pipes. You could even do a flow test by using a 5 gallon pail and cut a 3 inch hole in the bottom and set it over the 4 inch hole at toilet flange and then pour water into it with another pail. However, in anticipation you could have a flow problem, pour slowly with the first pailfull. Then if it goes down fine, then try to speed it up to equal the discharge rate of the toilet tank emptying rate. Make sure you have old towels and sponges ready to clean up back-up water if necessary!

[Stuff I say is not just theory. I have done about everything imaginable with toilets to solve problems with rentals with houses full of careless college kids and families with kids. Especially for the last 20 years of this same thing.]

Yah, what he said


Sounds like a good way to find the problem to me. It is a little work, but will get the answer.

Also, try checking to make sure the toilet bowl is filling up with enough water because if the bowl isn't full enough on some new toilets they will bubble. Sounds like something could be stopped up from the toilet to the stack though... Might check when/if you pull the toilet to see any standing water in the pipe.

!!If toilet is on 2nd floor, especially, or, if there are valuables in the basement below the toilet, you do not want to be doing my pour water down the flange hole test and having it overflow!!

For reasons of leaks around the wax seal and floor flange that often has void between outer edge of flange and floor (pretty typical if you have cast iron flange), I always caulk shut that void with silicone caulk before resetting the toilet, so that a leaky toilet has to allow the water to run out ontop the floor rather than leak through the floor and out through ceilings below. Also, when toilet leaks, the linoleum floor will permanently discolor after a while when the water wicks into the linoleum's felt backing.
