Low water level in saniflo toilet

Is it always low? Could be a partial blockage in the out flow pipe, causing the pump to stay on, or a sticking/dirty pump switch.

We have a saniflo. We were out, and our babysitter (who isn't familiar with saniflos) was in the bathroom and suddenly she said water was flooding out of the toilet - she said she had heard a loud noise...

If the apple core was right at the pump intake at the time the pump kicked on it very well may have been the problem. The pumps in those units are not the strongest in the world anyway. They are not made to grind up anything that has any bulk to it.

So the answer to the question in my opinion is yes. But you well want to keep a close eye on it for a while.

The saniflo keeps cutting in even when not flushed

Water pressure makes the unit kick on and off. It will turn on by itself if water is somehow draining back into the pump. It could be water leaking from the toilet tank into the bowl and from the bowl to the pump or the flapper on the check valve inside the discharge elbow may be stuck open or could be defective and allowing waste water to drain back into the pump, once it builds up enough water pressure inside the pump, the unit will kick on and off by itself.

I have a turbofush P macerator and the pump no longer switches off automatically after grinding and flushing has occurred

turboflush uses a pcb mounted pressure sensor to switch the unit on/off. there is a small tube that connects to this unit. make sure that is ok and connected. otherwise its a new pcb i'm afraid. look online more info from

My saniflo keeps coming on about every hour on its own and we cannot stop it making an awful noise

Suspect that you may have a leak at the flapper of the toilet bleeding water into the holding tank causing the pump to run unnecessarily.

Replace the flapper and clean the mating surface.

How to install toilet macerator?

on your out put pipe make sure you put as few turns and bends in it as you can, this will help the pump out when it's grinding and pushing it up. also you will want to use schedule 80 pvc pipe if you can get it and make sure you prime and glue every fitting well because you do not want that to leak when it's started up. it's always good to put a check valve on it as well some where close to where it enters the tank and a shut off valve, the glued pvc valves are handy because you dont have to worry about them leaking
