Our plumber came by this afternoon and discussed with Lisa the exact placement of the new hot water heater. He indicated where he would like Lisa to drill three 1 3/8-inch holes in the floor to take the pipes for the water heater. (This saves us a bit of money because he won't have to charge us for doing it.) He can now order the hot water heater we want and (if all goes well) install it next week. If all goes as planned, I might actually be able to take a shower in the house (instead of out in the travel trailer) when I come home from my next trip to the Bay Area.
