Hey guys,
I've got an existing branch using 50mm waste pipe running externally in to the stack and reducing to 40/40/32 inside for shower/bath/basin
I'm moving the basin which basically means I'm replacing the entire branch as the basin is going to sit another 1.2m further away from the stack and come through the wall a couple of inches lower than the existing branch. The old branch will drop in to the new branch with a tee.
Am I OK to replace the 50mm pipe with 40mm? Seems its not quite common these days (this would be circa 2000)
