My Saniflo toilet is not pumping out the waste. The water fills the toilet but the pump does not come on. I can hear it trying yo come on, but it just makes a humming sound. What should I do?

Depending in the pump model, but most of them, the pump casing usually fills up with water about half way of the casing before it creates enough water pressure to pump the waste out. Once the water is pumped out, the pressure releases off the pump and the unit shuts off.

Water pressure makes the unit kick on and off. Most likely somehow water is draining back into the pump. Check the flapper in the flush valve, inside the toilet tank and see if its leaking water into the bowl and from the bowl into the pump. Also, in the 90 degree discharge elbow there is a check valve with a rubber flapper that opens up to allow waste to pump out and it closes to prevent waste water from draining back into the pump. The check valve may be defective or it may be stuck open allowing waste water to drain back into the pump and is making the unit kick on and off by itself.

There can be a blockage somewhere in the discharge pipe, the blade or impeller. Also the short discharge pipe or long elbow inside the pump casing may be split open or not attached properly and waste water is just cycling inside the pump casing. Worst case scenario could be a bad capacitor, the capacitor spins the blade and impeller, it that goes bad the unit will just hum and not pump any waste out until is replaced. You can also order parts through Saniflo if needed.

the connection between pump and outflow pipe is cracked under the elbow/backflow preventer has a rubber connection take backflow elbow out clean the rubber under it if ther is a crack in it the water keeps cycling back in tank so it thinks it is always full

This could be a problem with the capacitor that has gone bad or something stuck on the blade or impeller and is not allowing the waste to be pumped out. Typically when the capacitor has seized up or there is a clog on the drain pipe, blade or impeller; the unit will just hum and not pump the waste out and eventually back up on the toilet and overflow.

If you flush the toilet at least 3 times and water does not back up on the toilet then is working. In case the pump fails the pump will fill up about 3 to 4 gallons of water before it overflows or backs up. You can also try disconnecting the discharge pipe off the discharge elbow and place a bucket at the end of the discharge elbow and flush the toilet into the bucket, if water is discharged into the bucket then is working properly.

check level in tank may be to high and not shutting off valve /sticking fill valve /or flapper needs replacing

Typical saniflo costs about 500 quid incl vat from plumbase, prices vary according to what you need it to do.

It keeps making noise becasue the pump is still trying to get rid of the water inside.

it can't get rid of the water most likely because their is a blockage in the waste water pipe.

if possible follow where the waste pipe runs to. if it goes in to a loft or somewhere else VERY COLD there is a good chance that it has frozen somewhere along the pipe.

If you are tying to pump the toilet waste vertically (upwards) then as soon as you turn the power off to the saniflo, the waste will fall back down and in to the toilet - or over the top in your case, sorry!

You might want to accept the inevitable and get a bucket and start removing the waste water from the bowl. Make sure that you have rubber gloves and I suggest goggles and something protecting your mouth - in case you get splashed.

Easiest solution, is to remove the excess waste water, turn off the saniflo, pour some bleach in to the toilet bowl, then cover the bown securley with cling film to keep the rank smell at bay.

Other wise, start tring to follopw the waste water pipe and warm it up, either by directly or indirectly (warm air gun) or by warming the area around it.

Personall;y i am using the easy option. the cold werather won't last forever, but can you use a toilet elsewhere in the meantime.

In the meantime, Saniflo claim about 15 years as the lifespan, but i have never know a saniflo to make it past 3! they are not ideal, but may be your only option.

consider whether you could get a proper toilet waste pipe put in, as it WILL save money in the long run...

Hope this helps a little bit.

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
