Protruding taps create an obstacle inside the sewer line, disrupting smooth flow and providing snag points for solids. Debris and grit can catch on the projecting part, start to accumulate, and form partial or full blockages. The projection also disturbs the hydraulic profile, increasing turbulence and making flushing and cleaning more difficult, which raises the chance of stoppages and maintenance needs. The other options don’t fit: protruding taps aren’t limited to concrete pipes, aren’t inherently more expensive, and the idea that they can be inverted to “easily” do not address why they are undesirable for flow and maintenance.
