Take a look at this cold water ground problem in the
picture above, because I see it everywhere. If you have a copper water
pipe, make sure that you use a copper cold water ground for your
connector.
In the picture above, you noticed that there's a galvanized cold water
ground connector that should have been used for galvanized pipes, but
instead it's hooked up to a copper water supply line.
It would also be a good idea to use solid copper wires instead of
galvanized wires like the picture above, to prevent electrolysis or
corrosion, if you're planning on using it to connect to a copper cold
water ground connector.
Home Repair Tip : In other words, if you have a copper water pipe and
you want to install a cold water electrical ground to it, you should use
a copper cold water ground connector with a solid copper wire to make
the connection between the electrical panel and the cold water supply
pipe.
If you have galvanized water pipes and copper electrical wires, you have
the same problem. They do make dielectric connectors and you can usually
find them at electrical supply stores.
When asking so-called experts at home improvement centers for advice on
electrical problems like these, be advised, that they might not know
what you're talking about.
