My sewer line is clogged... I think. Attached to the sewer line are three things. 1. Upstairs. A toilet, shower, sink 2. Downstairs. A sump pump 3. Also downstairs. A washer machine. 2 and 3 are hooked to same pipe The washer machine was draining into the pipe when...holy crap... water shoots to the ceiling from the washer machine drain.. To diagnose the problem I: a)put water in the sump pump to kick it on....more water on the ceiling.... b)flushed toilet...water half way to ceiling c)used sink and shower...water raised a little over the washer drain.. To fix it i snaked from the toilet..my nearest guess is i got ten feet down...couldnt find a clog but the snake would go no further. I imagine it is a bend in the pipe the snake is unwilling to make it past. i tried snaking through. the washer drain... too many bends.. ok...i imagine the problem is below where upstairs and downstairs connect since toilet water made it downstairs...then the ceiling.... anyone have a solution...? Yes... I thought of calling a plumber..but would like to save the cash.. i'm cheap...i;ve heard flushing a cup of rock solt gets rid of roots....i am terrified at roots ruining my pipes... in response to the rude comment (#2) as far as the use of TP.. I use bunnies..not TP..contribute or move on..smart comments are not appreciated. the cleanout plug is inaccessible. The genious who designed this house decided the best place for a lowboy water heater would be almost directly in front of the clean out plug........the water heater piping is welded in place..
