We put in the toilet on sat. Since then every time you flush there is a big air bubble in the bowl, the other toilet we took out did not do this, poured a 5 lb bucket of water down it and that did

Remove the toilet & have a plumbing company power snake
as much of the entire homes waste drain as possible

Maybe clogged inside the home on most runs & also out to
the street,have them do as much as they can, out to the street

Remove all toilets, so they can do good job & you can check &
clean them from under it

Have them run a camera down ALL drains & to the street

Always the first thing with bad toilets. Take a big plunger and pump hard covering the entire bottom of the bowl. Blockages cause air breaks which cause the belching

If you have a Saniplus model then the vent connection is on the top right side of the pump casing if you are facing the toilet with pump sitting behind. The vent pipe needs to be minimum 1 1/2" and must be vented to the open air so air can flow in and out at all times. To the left side of the vent connection is the discharge pipe which should be a 3/4" or 1" discharge pipe. You can try disconnecting the vent pipe and run it with the vent pipe open, also you can disconnect the discharge pipe and put a bucket at the end of the discharge elbow and flush the toilet into the bucket, it will free flow into the bucket and there are no restrictions. That way you can tell if the problem is the pump or the installation set up.

Try turning off the water to the toilet, then old the handle down until you hear that all the
water has drained out of the tank. Then turn the water back on. Then take a cup of water
and put water on to the plunger on top of the tank. Check for air bubbles, if there are bubbles
then that is the problem. The tank MUST HAVE a certain amount of air in the top of the tank,
or it will not work at all. You might have to remove the plunger assembly and put some vaseline on the big O ring seals. To remove the plunger, take the screws off the stainless bent rod that goes
over the plunger, then remove the rod, or just move it out of the way. The plunger can be removed
by sticking the jaws of a pair of chanel lock "pump pliers", then grab the handles of the channel locks and turn the plunger assembly out.

Sometimes all you need to do is drain the tank down, and the toilet might work for a long time.
It's such an easy fix, a person really doesn't mind draining the tank.

Hope this helps

Hi,
Change the flapper with a generic one that will fit that toilet... the OEM flapper is **** and it does not allow for a good flush either...

Have you checked it out for any blockage in the toilet or drain line.

You could try a 6ft auger to try to remove blockage from toilet.
If it is a drain issue it is either blocked somewhere or the vent is not working correctly causing it to get air bubbles.

Check you tank for proper water fill level up to marked line. Also make sure fill line from fill valve is connected to overflow pipe to fill bowl up correctly.

Not enough water in tank will affect the flush.

From your description it sounds like the flushing orifices are plugged. The orifices are the little holes around the bowl or the big hole in the throat of some. A simple way to check if this is the problem is to get a bucket with aprox 2.5 gallons of water in it and pour it directly into the bowl and see if it goes right down. If it does, the orifices are plugged. Two of the most common causes of clogged orifices are hard water deposits and bowl cleaner cakes that drop in the tank. In the case of hard water deposits, we usualy acid clean the stool with muratic acid introduced through the flush valve. Be VERY careful when doing this, as the fumes are VERY dangerous and it can discolor colored porcilyn. May want to hire a plumber to do this. As for the cleaning cakes. You can pour some tap hot water through flush valve and dig into hole with wire hanger to remove as much as possible. I hope this helps.

The flapper isn't staying open long enought, try holding down the handel for a few seconds each time u flush.

Something is stuck inside of the toilet. About the only way to get some of them out is to take the toilet up. Shut off water to the toilet and flush it one last time.You need to use a plunger and push all the water you can out of the bowl. Remove the bolts that hold it to the floor. Youll have a little left over water you'll have to clean up after this next step so get something to soak up water. It may be easier to remove the tank now than to take a chance on damaging the gaskets. Just going to have to turn the toilet over and over and over and see if something falls out into the bowl. To repair this damage you're going to have to clean off the wax ring (messy Job) and get a new wax ring. They're pretty universal 3 and 4 inch are the same. PUt the wax ring onto the bottom of the toilet then set it back over the bolts that hold it to the floor and tighten it back down. Replace the tank and tank gaskets if you took it off. When I fixed mine I found a AA battery inside. That was all it took to plug it up every time you flushed toilet paper.

you mite have a cloged air vent. or if you have a septic tank it needs pumped. and a clog mite be at inlet of pipe. dig open inlet of tank pull lid, if you cant see the pipe where it enters tank, take a broom handle and stick in the opening. to see if you knock out clog. or call a septic service company,not a plumber. hope this helps. duane.
