Question about American Standard Cadet 3 Right Height Elongated Toilet by - ADA Compliant

2 Answers

Our Cadet 3 toilet is leaking, not from the bowl, the water in the tank goes down. We have replaced the flapper/stopper 3 times. It's only the level in the tank that goes down. We have consulted with Home Depot, where we bought it and a plumbing store and no one knows what to do. We are out of ideas...

    Hello to you too Mr. Guru :)
    No water on the floor or the underside of the tank.
    When the toilet is flushed it fills to the set point which I've marked with a pen.
    If I don't shut the water off to the tank it refills to that point.
    But, if I do shut the water off to the tank the level goes down ...
    Now it wouldn't be that much of a problem except we are on water meters and the rates in this subdivision are ' extremely high '.

    Hi Tony,
    The Cadet 3 doesn't have a chain. I know how to work with chain toilets, this is a plastic tower mechanisms. I think the latest flapper is working ' better ' after being in place for several hours. Last night I put food coloring in the tank water to see if it was leaking into the bowl. It didn't leak into the bowl. The water level only went down an inch and we decided that we can live with that.
    Your advice was very good especially the information about the float in your second response. It was the noise of the tank refilling during the night that clued me in to the problem.
    I should mention that we bought a ' knock off ' flapper from Home Depot for $17.00 and it didn't work. Yesterday after checking with them (H.D.) again we went to a plumbing outlet store. The gave us an American Standard flapper for $0.00 and said it was part of the A.S. warranty on their products... what a sock :)
    Thank you for your help but I am so tired of trying to resolve this that essentially I give up!

    We have hard water and mineral deposits are a problem. My husband is reluctant to let me pour CLR into the tank so we did clean the seal by hand. The flapper seems to be working pretty well right now. I turned it off again to see how much it goes down.
    Thank you for all your great suggestions. I appreciate all the time you've put into this.
    I'm going to hit the accept the solution now and let deal with more pressing problems.

  • When it is filling up does it in fact stop? If so, look down inside the back tank and look where the water fills (the little hose inside a tube in the tank) Does the water go over the edge of that little tube? If so adjust the float so it does not fill quite so high.
  • How much slack is on the flapper chain? If it is very tought it will leave that flapper up just enough to leak some water.
  • If there is to much slack that little chain will get stuck under the flapper and the flapper will not seal properly and leak water.
  • Make sure the handle is not at any extreme angle to where the catch arm (connected to the handle on the inside of the tank) If it is set to low then it will effect the way the flapper settle and flushes.
  • Also make sure the handle flushes and drops back down with ease. If the handle is sticking even just a bit it may prevent the flapper from sealing properly.

Regards, Tony

    • Another thing, toilet leaks can be deceiving. Sit in earshot of hearing the toilet run for a while. See if out of the blue the toilet just starts running for even a few seconds for no reason. It will be your float needing to be adjusted to lower the fill level or the flap. Or the float needing to be replaced.

    • Also make sure the float is holding its ground. If it does not hold steady above water then the tank will fill intermittently because the float determines when the water begins to fill the tank and when the tank is at capacity.

    • There are a few Cadets so sorry about the chain comment. Some have them and some don't. You are right, what a load about the flapper. Water costs these days and the sock is not a part you want going bad on you. Have you looked at the seal that the flapper seals against (against the toilet)? Sometimes they get some mineral deposits on there and then the flapper will not seal right. Take a scratch pad and gently clean it a bit and see if that helps.

Umm hello first of all

Ok so you replaced the flapper 3 times did this remidey the problem at all or just tried 2 more times?

Also it there any water leaking on the floor or the underside of tank were the tank is bolted to the bowl there is a gasket there, also were the fill valve goes in there is a gasket there to if none of these parts are leaking then the tank is not leaking. Or going down possibly not filling correctly have you ajusted the fill valve ?

About every 20 minutes or so, more water is released into the bowl from the tank. Toilet is less than 1 yr old ,model 4021

The flapper that stops water from entering the bowl after flushing needs adjustment. The chain is probably to short.

I have a new American Standard Cadet 3 that was just installed. After flushing, the water fills into the bowl. However, after several minutes, the water in the bowl slowly drains away and is nearly gone....

Sorry for problem with new toilet.
You say water is leaking out of the bowl?

Toilets have 2 parts:
1) Tank: where water is stored for the flush and is sealed with a flapper.
2) Bowl: where water flushes down.

a) If tank is leaking water, then flapper is suspect. Replace flapper and see if that works.
Lift up flapper and run finger around rim to see if there is a rough spot that would indicate flush valve is defective, and needs replacement.
See typical flush valve

b) If bowl is leaking, that is very unusual and would indicate a crack in the porcelain.

If installer sold you the toilet, it is his responsibility to make good on product.
All products are guarantee against workmanship flaws.

There is no easy answer for your problem other than the flapper is not holding the water in the tank It is the only thing that keeps the water from going into the bowl when a toilet is not in use...on ANY toilet. Not all flappers are of the same quality, so be sure to replace it with the EXACT style as came with the toilet.

Just installed the cadet 3 and here is what is happening. First let me say that the toilet it replaced was working good. The water filled very slow and the bowl would not fill much. I messed with the...

The amount of water in any toilet bowl is determined by its construction and no tank adjustment will ever change that. American Standard has a history of having small water surface areas in their low or ultra low flush toilets. Take a large container of water and pour directly into the bowl. If the ending level remains the same, then that is the manufactured level for your toilet.

Not all tanks completely discharge all of the water when flushed. Measure 1.5 gallons of water into a container. Turn off your water supply to the toilet then flush normally. Replace the water in the tank with your premeasured amount and observe this new water level. You might be surprised to find it is at the same level it always is. Since water weighs more than 8 pounds per gallon, one concept used in todays toilets is to have more than 1.5 gallons of water in the tank and use the extra weight push the water past the flapper at a faster rate while designing the flapper to drop after only 1.5 gallons have passed through.

Tiolet tops up tank every 10 minutes or so.

With the toilet tank topped off, turn off the water supply. Then put a generous amount of food coloring in the tank. Wait ten minutes. If you see colored water in the bowl it will confirm that the flapper is leaking and needs some adjustment or to be replaced.

Toilet tank looses water over time

As long as there is no water leaking from the tank to bowl connection, you are OK. You would know if it was leaking here, because you would have water dripping out onto the floor.

Verify that the water level in your tank is below the top of your new flush valve's overflow tube. If the water level comes to the top, it will overflow into the toilet bowl. This can be easily fixed with an adjustment to the fill valve.

If the water is not overflowing into this tube, then the only way you can lose water is through the flapper. You said you changed the flush valve, which would have come with a new flapper attached to it, but maybe buy a new flapper and see what happens???

Tank adds water approx once every Hr, how do I

Sounds like your flapper isn't sitting properly. Put food coloring in the tank and wait a bit - see if it goes into the bowl for a definite answer. A new flapper will cost about 6 bucks. Good luck.

Water disappears to below the bowl inlet and stop.

adjust the float up to make water deeper....make sure no obstructions around the flapper....flapper needs to rest tight to bottom of inside the tank..flapper is the rubber peice that lifts when you push handle

American standard cadet 3 leaking around seal

get a new filler assembly. the water in the tank is heavy enough to close the seal completely. or the rubber seal is not making contact. thats' why the leak.
change the whole assemble ususally correct the problem.
adjuste the flow to about 1/4 to 1/3 under the over flow. if that still don't give you the pressure. you ca adjust the flow tube to 1/5 under the cover. that is the max.
