Saniflo in garden room

Anonymous user 09/03/2024 - 3.08 PM

I'm installing a saniflo system 40m away from the house and the waste pipe is going to be buried under ground via a trench. It will only have to pump around 1 meter in height over the 40 meters with around 4x sweeping Bends in solvent weld pipe to get me to where I need to be. My questions is. Can I use mains water pipe (black 25mm mdfp pipe) under ground to go into the trench. I'm hoping this idea will limit any Bends that will slow down the flow rate and eleminate any joints that could fail under ground rather than (solvent weld). Any advice will be greatly received. Thanks in advance. Dean
