why does toilet fill slowly
Why My Toilet Flushes Slowly. When a toilet flushes slowly there are really on two possible causes. The water is either slow going out through the trapway of the toilet bowl drain or, the water is too slow going from the tank to the bowl and the siphon of the water out the drain never occurs. The siphon is the process that rapidly clears the bowl and its contents with the gulping of air down the drain at the finish.
