The following section delves into the toilet’s problems and their fixes.

1. American Standard Champion 4 Toilet Not Flushing Properly

One of these issues is most likely to blame if your American Standard Champion 4 toilet has flushing issues: Your toilet tank has too little water, issues with the flapper, a blockage in the drain, the toilet, or the flange.

a) Weak Flush

A weak flush could stem from the absence of slats on the toilet tank lid. The slats allow air into the tank so that when the toilet flushes down, air can fill up the space left by the water.

Too much seal will prevent water from dropping quickly.

A series of jets or holes around the toilet bowl could also cause a weak flush.


You can use electrical plastic hooks. Alternatively, follow the steps below:

Step 1

Take the toilet tank lid off and check that the water level is half or a quarter inch from the top. Alternatively, you can adjust the float, so it’s just at the top.

Twisting the screw can make the float go up or down.

Step 2

Check the chain to make sure it is not too loose.

Step 3

Take a 1-inch PVC coupling and slide it in so the water level is slightly higher. However, this will increase the flush from 1.28 to 1.3, 1.4, or 1.5.

b) Slow Flush

Mineral buildup in your toilet will cause it to have a slow flush.


Use a stiff-bristle toilet brush and distilled white vinegar to dissolve the mineral buildup and regain the toilet’s flushing ability. Consider adding a water softener as well to prevent this issue from recurring in the future.

2. American Standard Champion 4 Toilet Leaking Between Tank And Bowl

It occurs when you fail to compress the tank and the bowl gasket.


Apply downward pressure to keep the tank level as you tighten the nuts in an alternating manner until the tank is stable. Avoid over-tightening the nuts since doing so will cause the porcelain to crack.

If there’s still a leak between the tank and bowl, the gasket is either worn or not compatible with your toilet. Replace the gasket with a new Corky tank to bowl the gasket.
