I will admit that until you sent me the metric allen wrenches, I only had a 1/4" drive metric socket set.

But now I have a whole set of wrenchs. The problem was that the bay door was propped up on the only thing around (small plastic table) which facilitated me having to army crawl up into the bay where the AquaHot lives because some other numbnut parked his Tahoe in the hanger right next to the same door, so by the time I got up in there with the poor light, I had to army crawl back to the tool box and drag out the new wrench. However, some 5 year old kid in an electirc Barbie Car cruised up and whacked me about the same time, so I was already pissed.

Get where this is going?
