This Old House - Season 20 - Eps 14: The Watertown House - 14
The show opens with a plumbing and heating tour of the basement, with stops at: a pressure-reducing valve that steps down the incoming water pressure from 110 psi to a more useful 65 psi; no-hub cast iron waste lines; two-burner high-efficiency boiler; and a topnotch ducting job that interfaces with an air handler, humidifier and electrostatic air cleaner. Upstairs, the terrazzo floor is polished. Our team istalls a new window with guts of wood fiber and resins, a wood veneer interior and vinyl-clad exterior. Lighting designer Doreen Le May Madden takes us to a nearby lighting showroom to see what she has come up with for homeowner Sue Denny. Among the surprises is a fiber-optic lighting package.
