Hi,

I have the above toilet system. The system is loosing vacumn, thus re vacuming every 2/3 minutes.

 

It is NOT the pipework or the bowl. Anybody else had similar problems and found the cause?

 

Many thanks.

Check the seal on the empty-cap, and also around the cassette 'input' pipe, too.

 

(I know you said it's NOT the bowl, but I had a similar thing a few months back and checked and checked ... it was just one bit of paper that was caught just under the rim)

Is this the Vacuflush toilet with a cassette?

 

First just give it another flush as there could be something stuck between the ball and the seal in the toilet bowl. If it's not that try cleaning between the rubber seal and the ball (my toilet came with a sort of flat white plastic toothbrush tool for this). Next, have a look at the pipe as it goes into the back of the cassette docking unit - just move it slightly and you may find there was a leak there. Finally, if it's none of the above take the cassette off and push back the spring mechanism. There's a double o-ring underneath that might need replacing - available from Lee Sanitation for about a fiver. It should be well lubricated with silicone grease.

 

Also it's a good idea to switch the toilet off when you go out (along with your waterpump). If the vacuum goes while you're out and the toilet keeps activating, the motor will eventually wear itself out prematurely.

Thanks for that.

 

The only thing I could think of is where the toilet empties into the cassette. As said, a new set of washers could be a good place to start.

The thick o-ring located where the pipe from the toilet empties into the cassette shouldn't need replacing because the pipe that it seals is rarely disconnected. It could benefit from a good smear of silicon grease however. The o-rings that most people tell me need replacing are the ones under the spring mechanism where the casseete goes in, although in nearly 2 years I've never had to replace mine.

That's the one I mean, mate!

 

However, despite the fact that it isn't the pipework, it IS!!!!

It's where the bend from the toilet enters the cassette station. The ****** who installed it has cut the pipe short, so the bend doesn't enter straight......it's at an angle.

 

Another bodge up from ***** and ******.

 

 

 

Many thanks for all replies.

Fingers, the other thing to check is that the pipe which enters the back of the cassette station is 40mm dia. I had some problems when I first installed mine because the ##### at Lee Sanitation (although they're very knowlegable really), had supplied me witha 38mm pipe so it couldn't hold a vacuum!

Mind you, if yours was working previously then that's probably not the issue.

Anyway, if you're still having problems next week it's worth giving the boys at Lee a call (but call in the morning 'cos they don't pick up the phone after lunch).

Ok mate, thanks a lot for that. I'll let this silicone cure and see ...... If it doesn't do the biz, then I'll have a more serious look. Fairly sure it's the ridiculous angle that it's been put in at......

What sort of silicone are you using? I was suggesting silicone grease on the o-rings (which doesn't cure). Then again, since your're not removing the pipe at the back very often, you could use regular silicone around the pipe as it goes in I suppose.
