Toilet not obstructed but won't flush
 
This has me stumped. This is a new toilet that was installed two months ago. It has been working fine until a few days ago. Suddenly it stopped flushing which is to say that the water goes down the drain very slowly. Actually it just trickles out. The tank and valve are working properly and I have tried dumping a bucket of water directly into the bowl. I ran a toilet snake though it and there was no obstruction at all. So I pulled the toilet and examined the bottom and ran the snake from the bottom and still no obstruction. So now I figure that it must be the sewer pipe so I dump five gallons of water through it and it just wisps it away as fast as I can pour it. So I try a couple of more buckets with the same results. I reinstall the toilet and it's right back to the same problem. When flushed it actually acts like something is trying to push the water back up into the bowl. None of this is making any sense to me and I hope someone here might have a clue to what is going on with this thing. Thanks for reading this.

What happens when you dump additional water into the bowl? Still slow?

I suspect the toilet---did you turn it upside down and rod from the bottom?

Take it outside and do a test while it sits up on blocks---

Yes, when I dump water into the bowl it just fills to the top and drains off very slowly.

I pulled the toilet and ran the snake through it from top and bottom. It went all the way through and came out perfectly clean both times. I'm convinced that there is no obstruction in the toilet.

I'm beginning to think that it might be a vapor lock or some vent issue. Is this a possibility?

Remove toilet take it outside sit it up on blocks and stick a garden hose in the bowl. make sure it runs out the other side nice and easy. Tilt forward and do the same from the base OR double check that the toilet is TRULY clear. I went to a service call the other day, slow toilet etc. Snaked it the whole 9 yards... Turns out there was a HAIR CLIP (big plastic one) lodged in it that the snake was going right through because it was in the open position... I had to remove it with curved needle nose after I pulled it and tilted it forward and saw a piece of it sticking out...

Also remember to replace the wax ring after pulling the toilet off the flange (mount)

Tilt it forward and look inside, tilt it back and look inside etc SOMETHING is there, just gotta figure out what it is.

had one that clogged occasionally. snaked it out twice. bout a week it stopped up again. pulled it, looked both ways, no obstructions. installed again. few days later it slowed flushing again. At this point i'm about ready to buy a new toilet. Pulled it again, flipped it upside down and ran a small mirror down to about where the turn is, and there was an ink pen lodged in the turn. sometimes ya think ya got it and ya don;t.:thumbsup:

I had one some years back---round plastic disk from a box of diaper wipes--acted just like a damper in a heating duct---darnedest thing--opened and closed as it wished--

Have had a few of these over the years had to rig a special spring head on a toilet auger to be able to pull them back. :wink:

really seems like something is in commode....did you flush water down open drain..

This evening I pulled the toilet again, took it outside, and dumped water through it from the top and the bottom. The water pours straight through it quickly. In fact it flushed normally when I filled the tank with water. I snaked it again for good measure and used a small mirror to inspect the openings and saw nothing. I am thoroughly convinced that there is no obstruction. Since nobody commented on my vapor lock or vent issue theory should I assume that these things could not be causing the problem?

Yes, I dumped five gallon buckets of water down the open drain with no problem.

Vent problems will cause this exact symptom---

ben's plumbing 02-16-2012 08:05 AM

yes a vent problem can cause this symptom but I really never seen one totaly clog like yours..it blows trap seal in another fixture so I am kinda stumped..
