Merits of Water pipe in duct.
Wondering what the merits of putting water pipe (MDPE) in ducting is? Unless you lay the ducting reasonable straight getting 32mm MDPE through a 50mm duct would be difficult, so bigger needed, then there is the fact that MDPE is fine directly in the ground, and away from harmfull UV there as well. Got to lay the water to the phase one this week and am wondering if I should get some ducting or not?
PS assuming that I should not put any connections under ground anyway.
Most water boards specify the duct is sealed where it comes up into the house. I thought it was as much for preventing gas (be it methane, natural, radon?) ingress as water.
I poured Wiska Gel down mine. The foam seemed to act as a plug. It's magic.....actually that's Magic Gel but either would do.
