Bought a american standard toilet tank to replace our leaky tank. after installation and turned on the water, but the tank is filling very slowly. what could be wrong?

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.

theres probably debrie in flush valve, mite also try putting food dye in tank (any color) if it appears in bowl the flapper is seeping water and activating flush valve..

Serval reasons: (1) noise from handle chain being metal-consider switching to lighter plastic type. (2) The rubber flap which lifts up when handle is pushed down and seals "when handle is let go" to allow water to fill in take maybe worn to the point of needing replacement-Go to any Lowe's/HomeDepot and they will walk you through replacement process of just removing old one and putting ends in place over hooks to install new one. Takes me 1 minute to do. (3) Adjust the water cut-off valve that supplies water to tank so it can feel up rapidly by just turning the value. If value is hard to turn try using some oil or WD-40 on it. Remember that one way opens to allow quicker fill up and better flush and other way just turns water to toilet off. If now of these things work then just give me a yell and I can advise further.

Hi,
You have dirt in the supply tube or the valve...
Depending on what valve is in the tank you can take the top off and wash the dirt out...
Otherwise you may have to replace the float valve inside your tank...

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

Replace the fill valve. You can pick one up[ at Home dep or Lowes for about 20 buks. Close your angle stop at wall behind toilet. Drain all water from tank then remove supply loine from under tank. Then unscrew fill valve and remove gasket and all. Remember to put gasket in new one. :)

The water in the tank is not filling to the water line, thereby not providing enough water to flush properly. Adjust the float so that the tank fills to the water line

By "tank ball" do you mean the fill valve that is connected to the water supply line or the flapper ball connected to the toilet handle?

Hi AaronYC,

I'm Harvey the Master Plumbe.

Your problem is: Installed a new American Standard Cadet 3 toilet bowl and tank at home. When you turn the water supply on, the tank refills normally and stops normally. After you flush, the refill is very slow. When it refills normally the water comes out from the bottom of the pipe (i.e. the pipe that houses the float cup) and when it is refilling slowly, it comes from the top of the pipe. Sometimes (but not always), you can shut the water supply off and when you turn it back on, the flow of water goes from slow to fast instantly - but you haven't been able to recreate this consistently.

These are the facts. American Standard has been keeping costs down by out sourceing. Their toilets are now built in third world countries and parts are made cheap. They're all doing it. Quality control is pretty good but your toilet came with a bad "ballcock". That's the refill part on the left. Because it's new, if you take the ball **** back to place of purchase they should give you new. If not, they cost less than $ 10.00 and easy to replace.
