Please help.Toilet flush twice everytime I flush.
I do have one or two toilets which double flush all the time no matter what.Like I said, if all else is well,who cares?But I'd like to know what that noise is that follows the second flush,you know..burple,burple,burple...what is that?By the way,most of them are Gerber rear flush toilets.

just thinking about your information. You said if you slow down the water flow, the problem doesn't occur. I'm wondering if the problem would be solved by reducing the flow of water that goes down the little tube (don't know the name of it) that's attached to the intake valve and injects water down the center tube into the bowl.
If the bowl fills too fast, relative to the flapper closing, could that be causing the problem?
Somehow the flapper has to be pulled up for the second flush after the tank is filled or partially filled after the first flush, right?
It would take the right combination of extra chain and proximity of the flush lever and float arm, but I guess it could happen, particularly if the flush lever is pushed real hard or held down for several seconds until the float falls below the level of the chain on the flush lever, thereby letting the chain get tangled on the float. Does it happen when the flush lever is pushed lightly and quickly?
I guess that the fix would be changing the length of the chain and/or bending the float away from the flush lever and chain.
I compared the two toilet (one upstair and one down in the basement) and found the toilet that having problem with flushing twice (upstair one), the flapper does not closes after the 1st flush. It closes a few seconds later, which means that on the 1st flush ,all of the water did not exit the tank and go into the bowl. The level of water left in the tank after the 1st flush prevent the flapper from closing right away. When I flush the one in the basement, the flapper closed as soon as the water exit the bowl. Hope this info would help you solve the problem. Thanks for your replies.
1) Why doesn't the tank empty completely on the first flush?
2) Why does a second flush occur before the tank can empty and drop the flapper?
I'm still back where I started. I'm thinking the bowl is filling to the point of flushing a second time before the tank has emptied once. That still makes me suspect the flow from that little tube. What happens if you redirect it to flow into the main part of the tank?
When I redirect the flow, it still have the same problem. I suspect the problem is in the bowl, where I see a lot of bubbles pushing back into the tank which I think is preventing all the water from exiting the tank into the bowl when it flushes.
Thanks for all your help. I'll replace the bowl soon. I'll let you know if the problem is fixed.
Don't replace the bowl. I had this problem. The solution is to reduce the pressure a little at a time. If the pressure is too great the initial blast of the refill will lift the flapper. I know it sounds crazy, but it worked.
Try using a coathanger to clean the holes under the rim of the bowl and then shut off the water and pour a bottle of CLR right down the flush hole inside the tank. Let the CLR set for around 1/2 hour and fill the tank and flush. Lime deposits will build to the point of restricting the water going to these outlets.
The double flush is caused by the initial surge of water through the jet (hole at bottom of toilet) in low flow toilets using up the water in the toilet faster than the water can recover from the water tank. When the water in the toilet is used up, the siphon takes in air (gurgling sound),kills the siphon and the toilet starts filling up again as there is still water in the tank. The second flush occurs due to all the water not being gone from the tank.
You can simply lower the tank shutoff float real low to fix it ....but you risk the possibility of more stoppages than usual as you will not get the maximum toilet jet velocity available. To have your toilet work at maximum efficiency get a chain with a float or replace the existing float and set the tank water to highest water level (gives you max jet velocity) in the tank. What the float does (it is adjustable)is it will shut the tank shutoff stopper with some water still in the tank eliminating the second flush and using very little water.
I have 2 questions for you,
1- What brand of toilet are you working on ?
2- Do you live in a single family home or a multi story building ?

VERY SIMPLE problem to fix
1- The water going down the refill tube may have to much pressure keeping the flapper from seating properly
2- The water level in the tank is to high holding the flapper up longer then needed and this gives a double flushing action
So, water level does make a difference.
