Flushing the water system, clorox

After reading Art's article on flushing the water system, I decided it was time to do this on our IP35-165. I simply extended the pick up line and used a bucket on the sole. As Art noted, use 1/2 cup of clorox per gallon of water. We used 15 gallons to fill all the lines and water heater. Them we allowed this to stand in the lines for 30 minutes. It took over 45 gallons to flush the clorox out of the system. Process took about an hour. Thanks Art.
