American Standard 4021 White Cadet 3 Toilet Tank Lid - Answered Questions & Fixed issues

If your contractor supplied the toilet, then it is his/her problem, not yours. If you supplied the toilet, then: take a mirror and examine under the lip of the bowl. How does the glazing look? Are there areas without glaze? If so, these bare areas are a breeding ground for bad odors. You can try a thorough cleaning both inside the bowl and around the outside of the toilet with an amonia cleaning product. If you use amonia, DO NOT use bleach: the two combined create a deadly gas. Whatever you do, do not hang a bleach based product inside the tank: the bleach will eat away at anything rubber inside the tank. There is a bleach product that hangs inside the tank and disperses the bleach directly into the tube that leads to the toilet bowl. This would be OK.

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.

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

Replace or adjust the flapper.

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

You will have some movement..........If to much movement use shorter bolts or build it up eith wasers.

This could be caused by a faulty relay or switch in the control panel. It is best to have a qualified technician inspect the control panel and replace any faulty components. If the issue persists after replacing the faulty components, then it could be a wiring issue and a qualified electrician should be consulted.

To make the water level higher in the pan, the outlet pipe must be higher.

Adjust the float on the fill valve

Depends how old your toilet is, it may be a calcium build up problem on your little inlet pipe inside your tank, but first check your water shut off valve on left side of your toilet near the wall....It may not be open all the way OR the valve has an issue...

Hey, One thing is that maybe there might be some loose plastic shavings in the fill line. From the Factory? or maybe was inside the water line going to the toilet when you connected the line to toilet. Shut off the water and get some towels and something to catch the water and disconnect it from the toilet and use bowl or what ever to catch the water and slowly turn it on and see if anything comes out. Maybe if it is in the line inside the toilet it might fall out by lightly tapping on the fill line inside the toilet to help it fall out. Just a thought when you said it "Sings" that sounds like trash inside the line going to the filler tube and bowl, hey try it who knows it might work. Okay

Hi, First, carefully remove your tank lid, and place it where it won't break or fall. Look for a four-digit number located on the back of the tank, near the water level mark. This is your tank model number. If the number starts with a two, it is a one-piece toilet. Then....visit this link: https://www.americanstandard-us.com/parts-support/faqs/toilets Good Luck!

water level to low or drain partial clog

More likely the sensor has malfunctioned.

these are called phantom flushes. the water is slowly leaking around flapper or the is a scratch of the flapper seat. I use fluidmaster parts

Toilets wear out from mineral deposits. Fixn may cost more then new. Googl used commodes first

air bound or pump overheating

Water turned off or fill valve bad.

I think it's not a wise decision to clean a toilet fill valve, rather than buy a new toilet fill valve and replace with the old one. Thanks.
