Neither Lisa nor our plumbing contractor have been able to get an answer from Fernley Electric, which is a pity since their office is right around the corner from the house. The plumber will contact an electrical contractor in Yerrington (the Lyon county seat) with which he's worked and let us know something next week.
Speaking of internet connections, she tried connecting the DSL modem from Mehama to the lines and called technical support. After working with them, AT&T concluded that the DSL modem we have isn't compatible with our service here, and they'll have to send us hardware after all. Sigh. Hope it works!
According to Lisa, things are coming along as smoothly as can be expected.
