Now, the 2376 desert coolers without pumps: Many of these had a 3/4° hose or pipe from pan of cooler connected to sewer of building and many going into top of vent pipes on top of building, cross connection again.

The Kelso-Turner District alone has 212 coolers with­out pumps or float valves with a 3/4"pipe drain from fete® of Fam cooler going to top of 3" and 4f vent pipe with a 1/2" water supply, a cross connection again and sewer gas. For your Information, here are some very practical figmres: A 1/16" opening will run 30 gal. per hour at 40# pressure A 1/8" " 8 150 8 " 40# 8 A 1/4" 8 8 375 8 8 40# 8 A 1/28 1 8 1350 I 8 40# 8
