If it ain't broken don't fix it!No, not really, I initially had 5m and that was a slow pour!
I just cut 2 m off it and tried it, seems spot on to me
I can't quite remember the exact length, but I remember line lengths being a lot longer with taps like below. But once I switched to Intertaps (with a smaller diameter nozzle), the lengths had to be reduced significantly as I was just getting a trickle.
