I have a saniflo sanibest model with a toilet, bathroom sink and shower hooked into it. The toilet and sink work fine, no problems, the shower however will not drain, not even a little. The shower is on top of a 2"x8" platform with a 2" drain, i removed the drain line from the unit and a bunch of water came out of the shower pipe, also, I pushed in on the check valve inside of the side inlet and a lot of water came out of the sanibest unit, there seemed to be no obstructions and the pitch from the shower drain to the sanibest is way more than the 1/4' per ft. required. Any suggestions as to what may be causing this problem and potential solution would be greatly appreciated. Thanks.

Nah, that doesn't sound like the toilet or sink were hooked up wrong, your sewage tank is probably full, you can have it pumped out for $100 or so. They fill up every so often for w/e reason.

Either internal blockage or discharge pipe is blocked

Hi and welcome to FixYa, I am Kelly.

In short yes it will need plumbed with a smaller drain line to the home waste drain.

The unit uses a fast-rotating blade to reduce waste and toilet paper in the flush water, which is immediately and entirely released under pressure through "small-diameter piping" to the sewer or septic tank. No special maintenance is needed and the pump is sealed for life. This simple and cost-effective alternative to conventional plumbing is ideal for basement renovations and other home-improvement projects. Properly sized, a Saniflo macerating system can handle all the fixtures in a bathroom, including the sink, shower, tub and toilet & endash; even on a septic system. What's more, these fixtures will work up to 12 feet below and as far as 150 feet away from a septic tank or sewer line.

hello there:
sounds like you may be having a partial block in you're drain lines do too paper and things being flushed down the toilet you may need to go to the outside of the house and find the cap on the drain vent and use an industrial snake and run threw the drain lines to get ride of the clog this should solve the problem you should be able to rent one from ace....hope this helps you out thanks

Zoeller makes the best unit out there do you research first

See if you can adjust the highth of the saniflow,to make it kick on sooner. goodluck.

IS YOUR PUMP WORKING

Does the shower or sink back up into the toilet bowel after running for a few minuits?

If not:


The bowel is clogged. Fill it with water then use a plunger
