The macerator wont stop .and the toilet bowl keeps filling with water

sounds like there could be a blockage inside which is effecting the pump or the float switch look on the saniflo website for instructions how to clean etc or phone there tec department

you cant it is set by the bends in side the bowl all toilets are this way it is a trap design that keeps fumes from septic from comming in

Water pressure makes the unit kick on and off. Water could be leaking from the toilet tank into the bowl and from bowl into the pump. Or the check valve inside the discharge elbow (on top of the lid) may not be sitting properly or is being obstructed causing waste water to leak inside the pump, creating enough water pressure to make the unit kick on and off by itself.

Water pressure makes the unit kick on and off. If it's turning on by itself then most likely somehow water is draining back into the pump. It could be leaking water from the toilet tank, to the bowl and from the bowl to the pump. Or the check valve inside the discharge elbow may not be closing all the way down and is allowing waste water to drain back into the pump creating enough water pressure that makes the pump kick on and off. Inspect the flapper on the flush valve and the check valve on the discharge elbow on top of the macerating pump.

Water pressure makes the unit turn on and off. It will only activate on it's own when enough water pressure is present. Most likely it can be water leaking from the toilet tank into the bowl, and from the bowl into the pump. Or could also be that waste water is slowly draining back into the pump through the check valve on the discharge elbow, creating enough water pressure that it will make the unit kick on and off.

indicates perhaps a faulty pressure switch. otherwise: this happens often in hard water areas due to build up of limescale. Use a descaling agent (acidic) to clean the saniflo - can be introduced via the toilet bowl.

te esay way rock slide or float in the cistern to the left
so with less water cistern will be filled

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.

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.

If there is a air emiten valve on vent ? Remove it than try to see if it works properly. If this works you will need pipe vent outside
