To ensure that our water line does not freeze we have to bury it as deep as possible. We ended up making it down about 6′ which should be adequate. To add a little extra protection we installed 2″ rigid insulation.
Other things to think about when it comes to your well is size and location. Our well is only about 15 feet from the foundation so it wasn’t too far to go for the water line. We installed a 1″ Line in PEX tubing. We are also going to use pex in the home.
