How to Install a Ground Jumper on a Water Meter

Most houses use the water supply line to provide an grounding path for the electrical system. If the ground wire from the electrical panel is attached downstream from the water meter, a jumper wire must be attached to carry electrical current past the meter. If either of the pipes attached to the water meter is nonmetallic, this grounding method cannot be used. Installing a ground jumper wire is a relatively easy task that can be completed in about 20 minutes using common hand tools.Water meters , Single Jet Water Meter , Multi Jet Water Meter , Plastic Water Meter , Remote Reading Water Meter ,


  1. 1

    Locate the water meter. In most homes this will be located on the lowest level of the house and on the side of the house facing the street.

  2. 2

    Attach a grounding clamp to the pipe on each side of the water meter. Place each grounding clamp 3" to 6" from the meter. Take the bottom "U"-shaped section of the clamp off, then reassemble the clamp around the pipe. Tighten each clamp hand tight, being careful not to crush the pipe.

  3. 3

    Cut a section of grounding wire about 6" longer than needed to stretch from one grounding clamp to the other.

  4. 4

    Insert one end of the ground wire through the round hole at the top of the grounding clamp, extending out the other side ½". Tighten the set screw to hold the wire in place.

  5. 5

    Insert the opposite end of the ground wire into the second grounding clamp, and again tighten the set screw. Ití»s important to leave slack in the ground wire so the water meter may be removed without disrupting the wire.
