Thanks, JoJo.
Varga: I know it's easy to patch, the problem is that it's a load bearing wall. We don't have any construction friends to help and Tommy doesn't want to do it without someone there who knows what they're doing. Unfortunately, in our area, the garage gets up into the triple digits just before spring so we'd have to do some major renovations before it would be worth putting everything in there. But, yeah, the sump can hold all the extra water. In fact, I already marked the water lines when everything is off so we know exactly how far we can fill it up.
We're trying to do it right the first time Al! We definately don't want any unforseen disasters. But the good news is that our insurance company said that the tank is covered the same as a home appliance so if anything gets damaged in our house due to a flood from the tank or the tank gets damaged because of a faulty pump or the inhabatants get electrocuted (we're getting a ground probe anyway), then it's all covered.
