Just wondering what people would recommend for minimum size on an air compressor to blow out lines for winter. Sears has one on sale for $59.99 that is 100PSI, 3 gallon, oil-free.

Not looking forward to winter,

Exactly how we did it last year.(no use-over though), Just finished the same procedure last week.

Was surprised that the pump will draw with as little as 2gal in the fresh tank...put 4 in, and pumped it thru everything, incl some in the black tank. The "taste" was gone after the normal Spring bleach out.

Trying to deal with the very thoughtful pump location in the Classic, with or without the syphon (option?), was a real PITA.

AF portion of Winterizing was done in less than 45min.


The 100psi unit should do the just won't have the reserve to keep a constant 40psi for more that 5 or 10min at a time. I usually keep the air on for at least 1/2hr @ 35psi while draining the low points, fresh and black tanks faucets etc.

With a water pressure regulator set at 60 lbs, it seems that have the air pressure at 60 lbs. is ok. Worked for me anyway.
