Should I dig my water pipes underground?
I live in Delaware, so it gets in the 20s sometimes in the winter. I'm planning to put plastic instead of existing copper lines.
The current configuration is very odd. The pipe goes underground and then up into the heater. But from the heater all pipes are exposed. I don't understand the point of burying one part and not the other. Any advice will be appreciated.
The earth underground maintains a temperature of around 45 to 50 degrees depending on where you are and how long a duration it is exposed to sub zero temperatures. If the are is heated by all means leave them exposed but its buried for a reason to capitalize on that 50 degree earth. Digging it down to below the frost line will keep it from freezing. Also you may wish to go with copper so you can apply Heat tape to keep it from freezing. Good Luck
