SewerDefender - Drainage Non-Return Valve

non return valve for toilets

About half of all flood claims are due to back-filling of sewerage pipes. This causes ‘foul’ water to flood the property from the inside by flowing back via toilets, plug holes, waste pipes and so on. No matter how many flood barriers or how good your wall sealant, they do not protect against flooding from inside.

The traditional solution to this problem has been to sink a new manhole outside the property and fit non-return valves to eliminate the possibility. But this is a very expensive and time consuming process and we thought that there must be a better way!
