Hi

We have a polyethylene pipe in home as a sewage and drainage pipe. Size of this pipe is 125 mm and in vertical section of this pipe we have a manhole. My question is how do I close and stop the main way of this pipe by retrieval stopper?
Because I have another way (pipe) for drainage, there isn't any pressure on stoppage( may be 2 metere column of fluid)
