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.

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

The new toilet has more flushing volume than the old one. The system should handle this. The problem could be the vents on the roof are plugged or something in the line is obstructing the flow. You will need to contact a plumber

How do I fix a toilet that bubbles (small air bubbles from below) and flushes slow, and not completely very often?

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

Why does my toilet belch water after flushing

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

Cant find any thing in bowl ,replaced air tank drain is clear and still does not flush replaced bowl and flushes this is the 4th toilet with same problem cant find anything in any bowl we changed

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

Leaks from tank into bowl and when flush as it

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...

Toilet when flushed makes a large bubble surface from the hole. Sometimes the toilet will not flush away a bit of tissue.... very frustrating..

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.

I have a weak flushing toilet of this model. Water does not fill tank fast enough to create the weight of water needed to start a flush. I've looked in the tank while lifting the flap and see that as the...

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.

BRand new elongated Cimarron shoots water out of bowl durng flush

Is the fill line in the tank loose? Does it just shoot water into the tank itself? I had this issue until I realized the while fill tube is supposed to be pushed into the black cylinder/small plastic tube in the middle of the stopper assembly. After i pushed the line into the tube, the bowl would always only fill a little bit. Now it fills almost a 3rd of the way up the bowl and doesn't bubble during flushes.

New American Standard Flowise toilet won't flush

You have a sewer is entirely possible for other things to cause the toilet to loose water as they drain....but only if there is a sewer problem.....that is why there is an air gap between the toilet and the tank...(the trap) now I have been in this industry 35 years and the jet you speak of is in the bottom of the toilet that directs and forces flow down and out of the bowl as do the many small holes on the underside of the bowl lip ( I suspect I have seen it MANY MANY time in the paste) that your old bowl may have had lots of calcium or lime build up (using lime a away occasionally helps) in the holes under the lip as well as other places...which reduces water flow and there by reduces pressure......but what you are describing is definitely sewer related....other water sources causing water to drain...bubbles...etc..I had a similar problem that occurred about once every 2 years in one of my homes...I had a tree root growing into my sewer line would flush but on occasion...debris would get caught and a good plunging would help...but eventually...(twice) I had to rent a 3/4 inch snake from Time Rental...with a cutter head on it and remove the problem. Now your problem sounds exactly like an air gap that an overflow or something related is causing a vacuum assist when large amounts of water are drained...(ie...tub...washer...).as this happens the force the water carries and the lack of access to air in the flow causes vacuum "tugs" on other water sources attached to the sewer....take of your clean-out cover (usually in the back of the house and if you see water standing in it ....sewer problem....also you can have someone flush the toilet and eyeball the sewer/ see how it drains.

I hope this helps....good luck...thank you for rating my effort...the Fang.
