We had not actually felt any hot water from the taps in this house since we got here. The kitchen sink took 75 seconds for even warm water to show up. Splashing cold water on our faces was the norm in the farthest bathroom. All of that has changed. We have installed a hot water recirculation pump. I did it myself. There is hot water on demand at every tap. These are wonderful devices that everybody down here knows about. Carol has pointed out that the hot and cold water seem to be reversed in the kitchen and that she wants it fixed today - picky, picky picky. My guess is that she will not end 44 years of marriage on this point.
