Here's something a carpenter asked me about yesterday. I haven't gone to his house to look at the situation yet, but here it is: Whenever the pressure tank kicks on, his modem for internet resets itself, turns off and on. The modem is plugged into a surge protector and nothing else on the surge protector powers off and on again. He had an electrician come out who told him it was a modem problem and to get a new modem, but the new modem does the same thing. The house is and old hunting shack and the pressure tank is only 120v. It is not hard wired but plugged into a receptacle, so it's possible the p.t and modem are on the same circuit? Any ideas what would cause this to happen?
