My swamp cooler is rusting from the inside out, but will hopefully last awhile longer. Last fall I shut off the water & drained the line, but the shutoff valve must have failed. Water in the copper tubing froze and split the tubing. Took all day to get new copper from under the sink, between two walls, through the hot attic, & up to the cooler. Got a new valve and hooked it all up. It's finally working well again -- and next week is supposed to be much cooler, and rainy.
