I have been asked to do a couple of these here and there and had a couple of questions. Do you guys sub out adding the electrical or do on your own? Most of these are close to the house or business and can tie into an existing outlet in the garage (GFI). Have any of you ever tried the low voltage water pumps? I have a few lighting customers and was just curious if they even work well. And do any of you put these on timers? And do you install any type of safety switch for the pump and low water level if customer lets it run out of water?
