My cadet toilet does not fill. I have to open the tank and push the valve to get it to fill. Do I need to replace a part ?

The American Standard Cadet 3 flowise one piece toilet uses a flapper valve with a soft nylon washer to seal against the water outlet.
Over time this nylon washer develops 'puckers' causing water to seep between the nylon washer and the seat of the flapper. This seepage causes the water level in the tank to drop to a point where the water inlet valve opens to replace the lost water in the tank.
There are two ways to correct this problem:
1. Replace the soft nylon washer on the flapper, or
2. Replace the entire flapper valve.
Hope this solution helps.

Valve fully open on inlet going into toilet if it is then fill valve needs to be replaced check water line for any abstructions that might interfere with water going into tank.

Was taking over two minutes to fill. Problem was with fill valve.
To resolve problem either replace fill valve or remove the flow restriction. Here is how I done it.

Turn off water!!!!
Remove the supply line.
Inside of the fill valve is a rubber piece. It is about 3/4" in diameter by about 1" long. This rubber piece has become distorted after years of use. This has to be removed.
Believe it or not, use a corkscrew and thread it into the rubber piece that is located in the very lower section of the fill valve. You can't see it so you will have to feel. Pull it out.
Re-connect the supply line.
Turn on water.
Check for leaks.
Problem solved.
NOTE>>> This only works for American Standard fill valves.

Hi keithn60...

I had the same problem one time with my toilet tank, the answer is to put some silicone on the seal washer between the take and bowl assembly and to use a level on the tank to tighten it just enough to be level and not leak.
Please take time to rate me

This is diagram of a typical toilet tank setup if the refill tube is not putting water into the flush valve as pictured the toilet will do what you have described.

Is the flapper valve slow to return to the closed postion allowing water to flow through the flush valve? Make sure the toilet flapper is moving freely and is sealing properly against the flush valve. If there is no lengthy or continual water flow in to the toilet bowl then this is not the problem.

Is the water valve on the water fill line to the toilet tank fully open? This may seem silly but it could be this simple.

Check to make sure your fill valve is opening fully. If you have an older toilet there may be some deposits that need to be cleaned way to allow free movement.

If toilet does eventually fill to the desired level, there is no leakage, water valve on fill line is fully open and fill valve is opening fully then recommend you shut off water supply, drain toilet and disconnect water fill line from the water valuve and toilet tanke to make sure there is not a blockage. If the water line and connections are clear you may need to remove the fill pipe in the tank and check for blockage. If this is very old, conisdering the cost and effort, it may be simpler to replace at this time rather than trying to extend the life.

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.

You don't have to replace, You just need to adjust the fill valve. If you have the ball **** type just tight the top phillips screw. If you have the newer type, close the water valve under the tank and Push down a plastic ring at the bottom of the filling valve, Push down the top of the valve, lift the plastic ring to it's place and open the water valve.

Went to Lows and got a new fluid master water valve. Before I got any advice it's done.
