I have a house with sump pumps on two sides. In the rainy season they run about 5% of the time. When one fails, as has happened a couple times, water runs gently across the floor to the other pump; no big problem.
The pumps are plugged into separate circuits.
My neighbor (an electrical engineer, not an electrician) is pretty insistent that those outlets should be GFCIs.
Is that required by code in California? Is it a good practice?
