    Top floor toilet sometimes doesn't empty
    Hi,

    Our bottom floor toilet works Ok but the top floor toilet doesn't fully empty unless the bottom floor toilet has just been flushed.

    Would this mean that we need a new septic system or is something wrong with the toilet?

    Thanks!

    Use single ply paper and raise the water level in the tank as high as it can go

    It is not a problem with the septic system or when you flushed the upper commode it would flood the downstairs bath.

    I have one that most repair plumbers miss.. Look down at the bottom of the bowl. If there is a small hole, then that is a jet that starts the syphon action. If it's clogged the water will just swirl around and slowly go down leaving solids behind. Take your finger,(UGH! ) and run it around the inside of the opening. Over the years minerals build up and cut down on the syphon (flush) action. If it is rough or you feel build up, take a table knife and put a bend in it to get around the curve in the bowl and chip and scrap it clear. Next take a coathanger and clear out the holes around the rim. They start the swirling action. And last, check the water level in the tank. It should be 1/2" below the top of the over flow tube. And speaking of the overflow tube, Make sure the small 1/8" tube from the ballcock to the white overflow tube is connected so it discharges in it and that it's flowing when the ballcock fills. This is what raises the water level in the bowl. For a good solid flush they all have to work together. Hope this helps . Tom
