Double Flush and not all GONE
Hello all. So I have one toilet at my home that I have no idea what else to change. Here is my issue. When flushing it does what I call a double or triple flush. In other words the toilet bowl empties, but the toilet resorvoir tank has not emptied out so it flush again, and sometimes again until the flapper closes. I have lowered and raised the water level but still same results. As it flushes many times it will not empty it out and leave toilet paper behind or anything else... I have changed the Flapper and Toilet valve. It seems as if there is not enough pressure when empting out the tank. Not sure what else to look at. Any ideas... Thanks

My guess is that it's either clogged or the vent is blocked.

As for clogging doesn't seem like it but will go ahead and use plumbing snake and check... As for the vent tube, is there only one at a home or more then one? I ask cause my other bathroom works just fine as well as my sinks and tubes. Please let me know. Thanks

That depends on the plumber and the circumstances behind the layout of the bathroom. A lot of people don't like vents. They think they look ugly, so they ask us to minimize them. In that case, if they are all tied together, you could try snaking the vent, and not even find the clog, depending on which way the snake goes. It's definitely worth a try, though.

I'm not really sure I understand exactly what is happening with your toilet, so i'm not saying a clogged vent is your problem, just explaining what you might run into.

The problem with my toilet is as follows:
1. I flush the toilet (toilet tank water level is about 3/4 below overfill tube)
2. The water in the toilet bowl begins to leave, then fills up again, and leaves again and fills up again and leaves again.
3. All this on #2 happens as the flapper is open during one flush as it empties the toilet tank.

From what I have always seen, the toilet usually fills up and begins to flush as all the water leaves the toilet tank with one flush... Not multiple flushes as I am having which i believe is the cause why it does not flush correctly and leaves behinds paper or anything else. Is this a better explanation?

no plumber here but I think the tank is filling up because the line is at least partially clogged, the level in the tank has to drop a certain point before the flap will fall down to close. The bowl has to be draining some or you would have lots of water on the floor. Try comparing the actions of both your toilets to see how they differ,,

Sounds to me like the flapper in the tank is not the 1.6 gal flush style, but more like the 3.5 older ones, you will find a toilet will flush out more then the min once if you installed a regular type flapper in a 1.6 gal flushing toilet, fix this by installing a flapper designed for the 1.6 gal flushing toilet.

Dude I observed both toilets. I can say that the one that is working fine the water in the toilet tank is about 2 inches below the over fill tube.

Ron the plumber, not sure which flappers I bought last time but you have a point there since I believe this started happening when the flappers where changed. I did not know there were specific ones for 1.6. I do know my toilets are American Standards. I just looked up the flappers I bought an they do specify that they are for the older toilets, called Harsh water flappers from my local HD store... Will purchase the right one and see what happens. Thanks again

So I changed my flapper to one for a 1.6 toilet. If I leave the water level in the tank to 3/4 below overfill tube it will flush the same, 2-3 times instead of one complete flush. So I lowered the water level for it to do just one flush but hardly has any pressure which will cause for me to then flush twice in order for a complete clean flush... What else should I look at? How much water should remain inside the toilet bowl after a flush?

Ron The Plumber 05-30-2008 04:16 PM

Let water into the bowl via the tank, don't flush it, just lift the flapper so water can pass by it, watch bowl, where the water stays at a constant level, that will be the operating level in the bowl.

Alan 05-30-2008 10:21 PM

Do you have something stuck between the tank and the bowl? :huh:

hgiljr 05-31-2008 07:44 AM

So water level is fine but still not everything is flushed. So I began to compare both bathrooms. The one working fine I see it with more pressure when flushing/filling up the tank. Could water pressure be the problem here that when it leaves the tank it does not come out with much force to properly flush? It even has more pressure as it fills up the tank.

As for a clog between tank and toilet, not sure. How do I check that? arrrrrrrrrrrr

Turn off water to toilet. Flush Toilet. Lift flapper with one hand, while feeling into the opening with your other hand. McDonalds toys are a common clog in this area.

I have had this happen a few times. One time a tenant never cleaned the toilet and stuff built up in the little hole in the bowl slowing down the water entering the bowl. The other was when another tenants child tossed a quarter in the tank that managed to block that small hole. From what you describe I would bet the problem is between the tank and the outlet in the bowl. This is assuming you used a closet snake already to make sure nothing is blocking the waste line or the vent

Hello all. I have been traveling so not much done with this. So I have changed flappers, snaked the vent, poured several buckets of water down the toilet, checked for any stuck objects between the tank and toilet, raised and lower the water level in the toilet, and still same problem. If I lower the water level in the tank well that causes the toilet not to have enough pressure to flush, if I raise the water level then that causes the toilet to immediately flush and then still has enough water left to fill up again and flush itself again. This causes for it not to flush properly. In other words, when I flush the water does not swirl around enough to cause the tornado effect to perform a clean flush. It pretty much empties immediately leaving behind paper etc... This is mainly when the water level in the tank is 3/4 from the overfill tube. I observed toilets on my recent trip and the moment it flushed the flapper would close even though there was more then half the water in the tank. My toilet flapper will not close until pretty much the water is completely gone from the toilet. Toilet and tank are from 2001 and the right flapper is installed, at least for 1.6. Any other ideas or help? Thanks
