Rod Water

Which grounds better rod or water pipe and why is it better?

Can you please explain in details why one is better than the other and why? thanks.

In the USA

The quality of the earth connection depends on the surface area of the ground electrode in direct contact with the soil. The soil should be firm, not loose like sand. A 3/4″ metal water pipe has more surface area than a 5/8″ ground rod.

A metal water pipe more than 10 feet long underground is an excellent ground electrode. The problem is, many water companies are replacing the metal pipes with plastic. When that happens, the ground is lost. Also, meters and valves inside the house can be replaced with who knows what, and the ground is compromised.

Ground rods are okay. When driven into loose soil, the rod does not make a firm contact with the soil, and is not as good as driven in firm soil.

The 2005 National Electric Code requires that you bond your electric service to a metal water pipe if it exists. The code further requires that you provide at least one ground rod. If you have less than 25 ohms to ground at the ground rod, then you are required to provide a second ground rod.

However, if the building footing contains at least 20 linear feet of minimum 1/2″ diameter rebar, and the rebar was used as the ground electrode, you do not need to provide any ground rods, but you do have to bond the metal water pipe.

Ground rods generally are 5/8″ diameter, 8 feet long. A metal water pipe underground is at least 3/4″ diameter, and probably more than 8 feet long. The more metal there is in contact with the earth, the better the ground. Rebar in a footing is better than ground rods or water pipe. A metal water pipe is better than a ground rod.

If you need to provide a good earth ground for computers or sensitive electronic equipment, and you cannot connect to rebar in a footing, consider driving several ground rods, at least six feet apart, and run a continuous ground conductor from the service entrance equipment to the rods, connecting to them all.
