Back to today. Allan and Sharon came over for coffee this morning as a plumber was coming too. The verdict is that my hot water lines to the bathrooms should be replaced - there is no other fix - for a cost of about $2300. All of the current lines are 3/8" galvanized pipe that is corroded on the inside. Apparently, the main line into our community is partially to blame but the owners refuse to do a thing about it. Secondly, they used poor material that only lasted for 30 years. I was glad to have Allan here, as he agreed with what the plumber had to say. I will get another estimate before I go ahead with the repair.
We had a cool night last night - near 60 degrees - so I had windows open and no AC running. Yeah!
