First, low water in the toilet BOWL case. If the water in the toilet BOWL is low after flushing, I see four likely causes, in order of most likelihood -. 1) the fill valve is not putting enough water into the toilet bowl.
Test the Flush. If other drains seem to be working fine, check the problem toilet by dumping about 1 gallon of water into it from a bucket. If it flushes down fine, the drain is probably okay. If it flushes poorly, the drain is probably clogged (see above). When you flush a toilet, clean water in the tank goes rushing down the flush valve to wash the bowl and provide enough water pressure to force the waste down the drain. If your toilet has a lazy flush but the drain seems to be clear, poor movement of water from the tank to the bowl is likely to be the problem.
