Q12 – Do I need to “winterize” the system before the frost comes?

As opposed to regular irrigation systems, the PVC lines of which should be blown empty of water before the frost comes, The Plant Booster system does not need the same treatment.  Other than disconnecting the Faucet connector cap from the garden faucet, there is no need to winterize the system.  The 1/16th” ID polyurethane tubing simply expands with any frozen water in it, and that does not cause damage to the tubing.
