Just to follow up on the cold water situation--Two guys are in and out today, which had Sadie pretty worked up for awhile, but she's snoring now. In her defense, Sadie does always position herself between me and anyone else or me and the door. Anyway, after considerable fiddling, Tommy and Saul (Sah-OOL) decided to rip it out and install a new water heater. Happy ending: Hot showers and a new confidence I am not currently a victim of secret government torture.
