I have a saniflo, which does the toilet, one side does the kitchen sink and the other side does the shower & basin. Water from the shower & basin drain away very slowly ( so slow the the showe

have a blockage

check flushing mechanism at the bottom to ensure nothing blocks it and that it closes securely after flush.

Usually Saniflo requires 8" or 9" from top of p-trap to floor level, not from top of shower base to floor level. If the base is raised 8" then you will have enough room to fit a p-trap without cutting the concrete, if you had cut the floor to fit the p-trap then the base is not raised high enough to maintain the water pressure inside to engage the unit.

My saniflo-plus system is about 12 years old..recently it stopped draining the toilet, etc. I pulled the cover off the pump and checked for blockage and spun the cutter blades...The motor just hums....do I need to replace the entire encased pump assembly?? Help

If you mean that it self activates then the non-return valve is at fault by the sound of what you say

Zoeller makes the best unit out there do you research first

sounds like you need septic tank pumped out. or there is a clog in main line if city sewer. hope this helps. duane.

If you hear it making noise the motor isnt blown, but it could be clogged.

A quick an easy fix is by filling a 5 gallon bucket with hot water (or warm water) and slowly pouring it into the bowl. The warm water breaks the particles up further, and will help flush the unit out. Make sure you run the water alot after its cleared out (to flush the debris). You can do that by turning on the shower or sink (if connected). If you dont have a shower or sink just keep flushing the toilet.

The outlet is blocked , get an engineer in to fix it pronto

water inlet pipe blows off when toilet is flushed
