I have a jauzzi 1.6 elongated toilet. I bought it in 2008. the flapper broke and I replaced it with a universal one. the only one i could find to fit it. Every time I flush the toilet, the flapper comes off on one side. How do I fix this problem? Thank you.

Did you try to find a replacement flapper by specifying the toilet model, or did you show them what you have? If this is not a power assisted flush toilet, there aren't that much difference between flappers. Worst case you could replace the whole flush valve assembly with a generic type.

Order flapper assembly directly from American Standard.1-800-442-1902

I would put in a FluidMaster system.

Lowes used to carry some of the oversized flappers. If they dont anymore start calling the plumbing supply houses in your area. Hope this helps.

I trust you mean the "Flapper Valve". They are available and most hardware stores.
Get a Universal type as they fit most units. Take the old one with you. If you turn the water off at the wall it will stop it from running while you're away

it sounds like your flapper (flush valve) is leaking.
if you here your toilet filling up and no one flushed.
push down on flapper to see if you here the water stop leaking out. if so replace flapper. even if toilet is 1yr or less old. could be a bad flapper. hope this helps. duane :)

Here's the easiest way: Close the water valve that supplies water to the toilet. Lift the lid off of the tank. If you look in from the top, you'll see a long white tube in the middle of the tank running from the top to the bottom. It is called the overflow tube. At the base of the tube is the flapper, and it anchors to the base of the tube, and is actuated by the handle on the front of the tank pulling the chain connected to the flapper. Flush the tiolet, and you'll see what I'm talking about. To replace the flapper, you'll need a replacement. Remove your flapper and get a pretty good look at it. You can buy a replacement at any hardware store. A 'universal' replacement should fit, but take the old one with you to be sure. When you look at the new flappers, you'll notice a rubber ring attached to the flapper, and you may not have one on yout toilet. No worrys here, the ring can be cut out if yours is of the type that just clips onto two lugs at the base of the overflow tube. Install your flapper, hook up the chain and turn the water back on.
The chain should have just a little slack in it.

You need to replace the flapper and you will need to purchase one specifically for the Kohler toilet. I have the same toilet and tried using a generic flapper and from experiance, it didn't work until I bought the correct one and I'm a plumber! Have a great night.

Yes it is called the flapper and overflow houseing it will involve removeing from tank and is not and easy task, may want to try to by one that has a "hole in it to slip over the "overflow' and slide downto where you broke it.

Please rate. Thanks jj505
