Hi, I want to replace an approx. 1 meter section of sewer drain with a suspected blockage of dried cement (from a new extension building project). My question is what would the exact procedure be, if for example, the pipe is 15 cm in diameter? Would I just use a 1 meter length of new 15cm pipe connected with Fernco fittiings? I was wanting to avoid any "lips" at the joints. But if I cut out the 1 meter piece of pipe with the blockage in it, and then replaced it with a piece of pipe, say, just 2 or 3 mm shorter than the 1 meter length I cut out, would the Rubber fernco connectors be ok? Or could those gaps, with time, slightly impede the flow? Please see attachment, thank you.
