What size compressor?

Does anyone have a recommendation on the minimum size air compressor I should buy or rent to blow-out the water lines in a 38" MH ??

A small compressor will do the job, dies not require much pressure or volume. You might want to get something that will also handle airing up the tires. Several post here via the search feature regarding compressors. Porter Cable markets a pancake compressor that Is popular. I have one.

Actually, air volume IS important for blowing out lines, but pressure is not. 25-40 psi is plenty as long as you can get enough air volume (measured in SCFM, Standard Cubic-Feet/Minute). 2-3 SCFM at 40 psi should do it nicely. Many cheap compressors offer a lot of pressure (psi) but very little volume, so watch out for that.

Lowes has the Porter Cable 6 gallon pancake compressor on sale for $99 this season and is does a nice job on air lines and any size RV tire.
