LondonLuke Posted November 27, 2012 Report Share Posted November 27, 2012 Hi all Hoping someone with some knowledge of the above on here... Have to work on one of these tomorrow (well, indirectly) in that we are cutting power to a house with one. The client has said that if we cut the power then the toilets will flood - not something I have heard of before. Can anyone confirm??

beerdeor Posted November 27, 2012 Report Share Posted November 27, 2012 Yes it will they have an internal chopper and pump to push the waste through a 1 1/2 waste,good luck with the clean up ops atb Jim Quote Link to comment Share on other sites More sharing options...
Rupert Posted November 27, 2012 Report Share Posted November 27, 2012 No it shouldnt flood,there should be a non return valve on the outlet side. if you dismantle it some residual waste can escape. Quote Link to comment Share on other sites More sharing options...
TaxiDriver Posted November 27, 2012 Report Share Posted November 27, 2012 As long as they don't flush the toilet whilst the electric is off, NOTHING WILL HAPPEN if they do flush, the bowl is likely to fill but will often drain away slowly, if you wanna be sure, isolate the water supply to the cistern, then flush to empty the cistern Quote Link to comment Share on other sites More sharing options...
philm Posted November 27, 2012 Report Share Posted November 27, 2012 It will flood if you flush it with no power on. Quote Link to comment Share on other sites More sharing options...
hmr Posted November 27, 2012 Report Share Posted November 27, 2012 im a saniflo engineer.it will only flood if they continue to flush w/c or empty whb etc. Quote Link to comment Share on other sites More sharing options...
TaxiDriver Posted November 27, 2012 Report Share Posted November 27, 2012 It will flood if you flush it with no power on. Shouldn't do as the volume of the cistern should be less than the volume of the bowl surelyhave recent experience of this having had to change my mums saniflo macerator Quote Link to comment Share on other sites More sharing options...
Kes Posted November 27, 2012 Report Share Posted November 27, 2012 As far as I was aware, there is usually a short length of pipe from a macerator type loo which needs to be pumped to the mian system with normal falls. This means that, apart from the section with the need to pump (which will have fluid etc in it) that is all that might fall back to the loo. However since that would happen everytime the loo is used (pump not always on) each system must be fitted with a non return valve and as such will not flood unless dismantled beyond the valve or 'used'. Tell them to use the 'normal' one and leave the other alone until the powers back on ! Quote Link to comment Share on other sites More sharing options...

I won't fix the things, it's replace it or find someone else to do it. I have found some proper nasties in them. (I'm sure you have too).

LondonLuke Posted November 27, 2012 Author Report Share Posted November 27, 2012 (edited) Thanks guys. My understanding was that assuming they are isolated electrically and not touched then they should be fine - that appears to be the educated consensus here. Thinking we will tape the toilet lids down! I did question the client on what would happen to all the houses that have them in a powercut but they seemed so adamant that I thought I had best check!

As stated, shut the water supply to the WC and flush it before shutting the power off, foolproof then. One flush won't overfill the pan anyway.

Flashgun Posted November 27, 2012 Report Share Posted November 27, 2012 We had one of these toilets at work and one of my mates used it one winters morning he hung his coat on the door which covered the door handle , after he finished he flushed the toilet and the pumped kicked in and the outlet pipe was froze up and it pumped the entire contents into the cubicle and he couldnt find the door handle to get out !

hmr Posted November 27, 2012 Report Share Posted November 27, 2012 they should not be the only toilet in property anyway (manufacturers statement) because of this arising. Quote Link to comment Share on other sites More sharing options...
LondonLuke Posted November 27, 2012 Author Report Share Posted November 27, 2012 they should not be the only toilet in property anyway (manufacturers statement) because of this arising. Indeed, surveyors will highlight this when purchasing a property and can have severe impact on sale/purchase Quote Link to comment Share on other sites More sharing options...
Dougy Posted November 28, 2012 Report Share Posted November 28, 2012 why cant you give them a good flush through first using bleach or whatever product of your choice. It would make it a little more pleasant to work around just incase there are a few unwanted logs lying around. Quote Link to comment Share on other sites More sharing options...

oscarsdad Posted November 28, 2012 Report Share Posted November 28, 2012 I have one and just after I bought the house last year it packed up. I considered taking it out and unblocking the macerator myself but then decided I didn't fancy it. Glad I did! The bloke came around and arrived just as I was leaving for work and the whole house absolutely stank - my poor girlfriend had to hold open the bag he was clearing it into whilst I went to work early! Money well spent lol! Quote Link to comment Share on other sites More sharing options...
keg Posted November 30, 2012 Report Share Posted November 30, 2012 We have one fitted to a holiday cottage we rent out. Depsite a note on the cistern lid and also in the joining instructions, people still flush stuff down that they shouldn't despite having a "proper" loo next door. Tampon caused the last problem, our plumber described it as a "mop head". Quote Link to comment Share on other sites More sharing options...
jeburf Posted November 30, 2012 Report Share Posted November 30, 2012 We have to use these at work because the plumbing throughout the hospital is "peculiar". The are absolutely terrible things, I would never have one in my own home. They break so often we always install two in parallel so that when one breaks the other kicks in and takes over. The alternative is to have puddles of bloody clinical waste mess all over the laboratory floor. They are only used on liquid waste from our analysers so its not as if there is any lumpy bits to clog them up. Quote Link to comment Share on other sites More sharing options...
