September 16, 2021

The replacement of existing metal water service lines with a non-metal type and the insertion of non-metal devices such as water softeners in the water line may result in the loss of adequate service grounding. To ensure that grounding is not compromised:

a) An alternate ground electrode should be installed where a metal water service line serving as the grounding electrode is replaced with a non-metal line.

b) A grounding jumper sized in accordance with Rule 10-114 should be installed where non-metal devices are inserted into a water line serving as the grounding conductor.

When utilizing a metal water pipe as an electrode, connection as per Rule 10-118 should be made on the street side of the water meter as close as practical to the point of entrance of the water service.
