As I've written in previous posts, I'm in the process of rebuilding our house from a fire. I have 5wrap underground pex that was buried 4' underground that went into the basement. After the fire and the excavation for the new foundation, the line is now 15ft from the house. Can I splice this to get the rest of the way to the house, or do I need to run a new line from OWB to house?
I believe I have read before not to splice pex underground, but don't understand why. I found that Thermopex makes a really good splicing kit. If splicing is ok to do, can I put pex inside a 6" tile with insulation around the pipes and then run it into the basement?
