Drainage backflow

[Burnerman]

I've been working in my sisters place, in Keswick - her apartment was recently flooded out.
Unfortunately, the water level was high enough to allow sewage to come up and over the loo bowl with a rather unpleasant result.
To prevent this happening again, is there such thing as a back flow preventer, or flap type valve that would fit into the 4" soil pipe that could prevent this? I'd appreciate any comments or knowledge!
Cheers and have a good evening, all
John

I seem to remember a flap type device been fitted in sump pump situations, however I dont think this will help in flood situations.
In floods if it doesnt come over the bowl its coming through the door or windows or up through the floors. Floods are not at all pleasant, sympathies to you sister and her neighbours

Now that may be just the thing...I haven't come across this before. Access is a little tight though but I'll certainly think about that! Thanks very much! John

Thank you! Yep its not a pretty sight but people are much worse off in Cockermouth......at least in Keswick most places will be habitable before too long.
Cheers John

You're most welcome John. Ive been following the events on the news, my thoughts are also with those affected.

I would check with osma tech before using on soil pipe as it states only for surface and waste water not soil!
