We have a Progressive Industries surge protector that will cut power for either low or high power. We are full-time and it has cut power a couple of times when we had no idea there was a problem, and it wasn't someplace we had just hooked up at either. For sewer, hubby has a hinged piece of white gutter that he can take apart at the joint (easily) for a 4' section, or open up for an 8' section. The sewer hose lays in that and is at a nice angle to the drain. It also protects the hose from those guys with the weed whips.
