does anyone see a hazard in jumping a water meter(metal on street side only)THANKS GEO

GEO,

Do you mean making only one connection to the street side and not jumpering across the Meter? Or, are you doing this because the inside piping is non-metallic?

YES inside is plastic, someone is requiring it to be jumped anyway , it seems that it could be a problem if someone is relying on this to do something. THANKS

GEO,

If it's all plastic on the other side it sure doesn't make much sense to jumper it.

For what it's worth, where I am we are not required to jumper around the meter because they feel that the metal yoke going across it is adequate bonding. You can see the yoke in the following picture.

Does that(yoke) stay in place when they change a
meter? If it has a yoke, we don't need the jumper? I've always put the second clamp on any how. I guess it depends how close that the plastic is to the meter. No room for a second clamp? There has to be copper some where in the house, where it would need to be bonded back to the panel.

Steve,

I believe the yoke does stay in place when the meter is removed. I always did both sides too, (leaving a big loop) but was told that it was not necessary.

Bill,

Do all installations in the Long Island area use that yoke? Is it provided just to help relieve stress on the water-meter joints, or does the utility give another reason?

Paul,

I would guess it does serve to relieve stress and keep everything in place if the meter is removed. This is the common configuration with inside Residential water meters on Long Island. Some older homes have buried meters near the street connection to the supply.

In the photo above, I see what appears to be a jumper or something else bonded, with some green corrosion..

Are clamps usually placed without any type of anti-oxidant when the pipe and conductors are all copper? Is the anti-oxidant for aluminum to copper bonding only?

I sand the copper first, or emory it, then I put the clamp on. Then I put scotch coat on the clamp and pipe. (prevents corrosion on the clamp)
There's a lot of humidity build up in these basements here on L.I.

TG,

Yes, there is a jumper across this meter so it was not an optimum choice for this discussion.

I mainly wanted to show the metal yoke (underneath) that connects across and effectively bonds both sides by itself.
