So for full disclosure I am running PVC since when I was given the compressor I had a bunch of it laying around after using it as framework for an AgBag garage/shelter of sorts.
That said it or the preferred PEX makes retrofitting your system a lot easier than metal. Which is what I did with the heater core.
As I said it was a whim I had and as the core was just sitting there seemed like a way to test an idea. I figured if it worked to a degree I might upgrade if I needed.
heater core air line dryer
As a experiment I just grabbed what was laying around thus the braided water closet lines which just happened to be the right size for the core hook up lines. It does make it handy however as I can move it around and drain any moisture that collects in the core itself with the drop I just open the valve and blow it out. Prior to adding the core I had water in the line at the drop and also inside at the moisture filter which needed nearly daily blow outs. Since the core was added I have had nearly zero accumulation at the filter and open the clean out about once a week if that.
I'll no doubt upgrade when things begin to fail but/leak but it began as a test and so far the test continues>>>
Oh I forgot... I no longer use the bucket as it works without the water in it.



Give me ambiguity
