How to fix poor flushing action in American Standard CCAS1880?
- SSandra StewartAug 20, 2025
If your American Standard toilet has poor flushing action, there are several potential causes. First, the water level in the tank might be below the prescribed level; set it to the correct level. Second, the flush valve in the tank might be closing too quickly or not opening properly; ensure no material is stuck to the flush valve. Third, the flush handle or button may need replacing, so replace it. Fourth, the water pressure might be too low; ensure normal water supply pressure is at least 20 psi. Fifth, the trapway or drainpipe might be partially clogged; use a plunger or toilet auger to unclog it. Sixth, there might be no air vent; install an air vent according to the instructions. Finally, there could be air tube leakage; reconnect or change the air tube.
