110mm non-return valve

[mutley racers]

Hi guys. I am after some non return valves to stop water backing up sewer into toilets. Ideally to just wack in the manhole. There are lots online but would like a recommendation before buying. Thanks all

Hi
I’ve used these before to stop cellars flooding from drainage back flow.
Worked well.

Looking again the face`s aren`t large are they, so probably not for you this time with the weight of water involved.
Maybe see what flood protection companies use?

Looking again I don`t think it was strong enough for the weight of water involved, here`s one I found from a specialist.

(Err, some sort of time delay going on here?)
