The bathtub filled up with effluent when draining the laudry tubs. I am on
a septic tank.
At first I figured the tank was full so I had it drained. The guys who did
job said it did not look full and that they noticed nothing entering the
tank when the toilet was flushed. I opened the cleanout access and used a
snake to poke through a not very difficult blockage. The snake goes through
easily to it's fullest length, (50 feet).
However when I close the cleanout and switch on the landry tub pump again it
quickly backs up into the tub again!
To make sure there was not a blockage behind the cleanout I checked with the
drainout cap off that the water from the laudry tubs is coming the right
way. It comes through fine to that point but stops very quickly. The water
level in the drain pipe then slowly goes down will the pipe is almost empty.
Am I correct to assume there is still a blockage in the drain? How would I
go about getting it cleared?
