I have a run of 3.8m to the outside wall for a shower waste and a run of 4.5m for a kitchen sink waste.
I am looking at using 50mm solvent weld. I know I can get shower traps in 50mm size but for the sink could I just use a normal 40 trap and fit a reducer or does this defeat the point of using 50mm pipe.
