Re: DIY - discussion on building a DIY hookah diving compressor
For the most part, Ray gives good advice above. I would take exception with three points, primarily because I feel he didn't give them enough emphasis:
1.- In a DIY system you should use an oil-less compressor only.
2.- Depending on how you plan to use your hookah, air storage and the associated plumbing are not necessary. For hull cleaning, I would say there is no need.
3.- This cannot be stressed enough; only mil-spec breathing hose should be used. It's not a matter of how the air tastes or the hose degrading or whatever. It's a matter of breathing poison or not.
