The 1-18 Tub Bottom Holes,, and the Turnover Factor
When we got our 1977 Frigidaire WC in Gold, it had the lowest holes as "captainmoody's", along the tub's curved bottom. Unfortunately, the tub was actually damaged with a noticeable chip on the middle-side. Frigidaire actually replaced the tub within 2 weeks of delivery, and it was the same tub as "pdub's".
I did'nt think it made any difference, because it alowed more water to drain from the bottom, better for sand and dirt to flush-out.
It IS TRUE that the 1-18 Jet-Cone Agitator tangled clothes less, and turnover was greater than the older 3-ring agitators, due to the greater anount of air being pumped into the washwater through the holes on the agitator under the gray rings. If I put my arm down into the washwater next to the agitator as it pumped, I could really feel the pull of the agitator's force. I also felt the air being shot into the water. The machine ran GREAT with NO repairs, for over 17 years!
