We're running a water line from the house to the duckhouse. It's around 160' and not a straight line. We're in Maine, where the water line must be at 4'. We plan to put 1" rigid foam over the water line to add protection. The plan is to feed two frost proof hydrants--one at a garden and one at the duckhouse (with the option to extend the line later and add additional hydrants. Here are our questions: Should we use 3/4" PEX or 3/4" ADS Plastic Coil Pipe? Where the line comes out of the house, we are only at about 24" deep. How would you protect the waterline from freezing where it exits the basement and before it makes it to 4'? We will run the line without interruption to a T, where a short line will go to the first hydrant. We will then run the line to the second hydrant. Should we also run this one off a T to make future extension easy? Any other thoughts? Thanks in advance!
