We need to have a new water line put in from the meter in the parking strip to the house. We've recently had a new electrical panel put in and the electricians pounded two grounding rods into the ground outside our house. Because of this, will the house be just as well grounded if we get plastic pipe as if we get metal?
The two ground rods, assuming they were at least 8 feet long, at least 6 feet apart, and driven in almost flush, are good and sufficient for grounding.
The water pipe, if metal, would still have had to have been connected to the breaker panel as if it were a ground rod.
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
