I recently bought a home. It has 2 toilets upstairs and 1 toilet downstairs. I’ve been having trouble flushing the toilet in the master bathroom upstairs. When I go to flush it, the water in the bowl will swirl and some water in the tank will go out, but not much. I replaced the “chain and flapper”, but it didn’t seem to make a difference. Also, if I go to flush and hold down long enough, it will EVENTUALLY flush. Slow to flush… but will flush. The other 2 toilets in the house are fine and will flush without a problem. What could be the problem? To me, it seems that this toilet just doesn’t have the pressure to flush/recycle the water in the bowl.
