we live in northern ILL and are planning a new home. it is in an older area and was a previous home we tore down. The waterline 1/2 “copper is sitting on top of a flagstone layer about 40-50” below grade. It may or may not dive down to deeper service.
Is there a way to insulate this line so the code will be met? The line is still there but it’s too small and froze up in areas that did not have snow cover.
Our other choice is to jackhammer a trench in the flagstone to the house about 60′.
it will need a road cut to install.

IRC also state that all water and sewer lines must be at least 6 inches below the typical frost level for the area to help ensure that the pipe can't freeze.
For a new house, would you not want the water line properly installed and large enough?
To prevent freezing on shallow water lines, ensure they are insulated properly with foam pipe insulation. Additionally, keep a slow trickle of water flowing through the pipes during extremely cold weather. For extra protection, consider installing heat tape or cables along the line
We are weighing the cost of getting to the same goal--- nonfreezing water. the jackhammer could be expensive and you could save time and money using proper insulation. Does the plumbing code allow insulated lines that are shallower?
When the water isn't moving, insulation only helps for a limited time. A super-insulated house won't stay warm without a heat source.
It works!
