Leak from saniflo

My saniflo has developed a leak that comes out where the power cable goes in. I thought that this would be water tight.

My toilet is having a small leak from the cystern which meant the saniflo switched on, on its own, every 24 hours or so. I switched it off at the mains but had not realised about the leak so the toilet...

About leak, it may be that the washers are worn out, or you might have the nut too tight.

If the pump isn't working, the length or height of the installation is over the specification, or there are too many bends/elbows or the pump chamber is blocked. First try to check this and the right position and installation of the components (click over image)...


Additionally, I suggest check the troubleshooting section in the user manual:

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.

Our saniflo system works ok, its just when left idle, the pump seams to start up every 40 secs. I've flushed it and held up the ball **** and it stills does it. Any ideas?

One thing to check is the check valve may be leaking back, float may be faulty, toilet maye be leaking and filling tank causing pump to come on.

Check out this link with a trouble shooting guide for this unit.

This first kink has information on different types of Santiflo systems.

This next link has a trouble shooting guide that covers these issues.

High pitched sound in house

Saniflow units are completely silent, except when actually pumping. It's worth noting that because they are electrically operated they will not work if you have a power cut - so don't use toilets or anything else attached to them if there's no power or you'll be in big trouble!
Another point about the Saniflows... it may be neat to put them behind tiles, but they will require regular access for servicing so it's not really practical. I advise covering them with a panel that can be quickly and simply removed, if you must cover them with anything, that is.
With regard to the noise (and I ask this in all seriousness), does anyone else hear it? Although you've tried turning off the water at the mains, it's still possible for noise to be transmitted along water pipes from elsewhere (as can be caused by leaks, for example, which can be quite high-pitched).
Apart from that, thought turn to possible insect infestation - bees, wasps or other things depending where in the world you are! Maybe you also need to consider when it started and whether you can connect other changes in your house with that time. Also, is it continuous or intermittent? If intermittent, is there anything else that happens at the same time?
If you find a cause, please do post a reply, as I'm fascinated to know what this is! If you need more help, please post your question again and I'll leave it for someone else to have a go at.
Good luck!

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.

I thought my macerator toilet must be blocked as it wasn't emptying in the bowl and when I flushed again the water (and waste) filled more into the bowl and leaked out of the top of the macerator spilling...

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.

Looking at the Saniflow - I have water leaking right hand base

It should be a simple solution. The seal from the toilet to the piping has failed and needs to be replaced.You are probably looking at a parts cost of less than 20 bucks if you buy it yourself.

I have a sanigrind from saniflo and there is dirty water coming from the little hole in the bottom of the electrical subset box. Could someone help me get to the bottom of this.

The Sanigrinds are a little harder to work on. Most likely the electrical subset is broken this is why water is leaking out of there. You will have to replace the electrical subset, be careful though. If not aligned properly, it will brake again upon installation.
