Help: I have run my 3/4 black poly pipe form my house to my barn as a water source feed. I am about to continue my 2 1/2 to 3 ft ditch inside the barn to a "frost free" style water spicit(sp). The problem...in the future I am going to add a wash bay and I will want to tee off of my poly line to add the water for that. Would it be best to put my tee in now and bring it up floor level and cap it off ? If I do will it freeze the reat of my poly line? What is the best outside pipe to use when I add the wash bay? ...that doesn't freeze? Should I insulate the pipe?
