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.
McAlpine Rodent Barrier
Any good?
Looking again the face`s aren`t large are they, so probably not for you this time with the weight of water involved.Hi. It is really for flood protection and this is just for rodents i believe
