Enough air to blow out water lines?
(Spokane, WA USA)
I need to winterize a double wide moble home. I need to blow out the water pipes. I won't have power for my compressor. Can I do it with a compressed air tank? I have 7 gal air tank that rated for 150 psi.
I have a regulator and plan on setting it to about 50 psi.
Will I have enough air to do the job. If not what size tank should I use?
