I think you have covered it all. Just last flush !

r u using any glue to seal the gasket and oring

The reason the tank doesn't sit down on the bowl is cause it's not supposed to just sit flush from the start. Your suppose to tighten the tank bolts down in order to get a water tight seal. There is also these little rubber " U " shaped things that sit on the porcelain lip on the back of the bowl thats what's there to protect it from cracking when you tighten the bolts down. Just place 1 on the right side and the the other on on the left side. and tighten down 'til the tank touches the bowl.

u should be able to just replace with a universal one

You have replaced the flush valve completely? If so and the unit is still leaking, you may have a small crack in the tank or your just not getting the tank to bowl fittings tight enough. Also, they make two different thicknesses in the tank to bowl gasket. Make sure you are using the thicker of the two. You posted this under the American Std. thread, so if this is correct, give them a call. There could be a recall on this particular toilet due to a flaw.

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!

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.
