Post by: Mi Steam on June 07, 2020, 01:08:05 am: Jim, I bought one of these from Amazon and it has worked for me.

Thanks again for the ideas.

Plugs into a 110V outlet and "blows off" at predetermined intervals. Well worth what at the time was a little drop in a fairly large bucket.

my compressor is an 80 gal. 2 stage, when I bought it I removed the drain valve from the bottom middle of the tank & put on an elbow & 18" piece of pipe & then the drain valve back on so I can see/reach it much better, that doesn't mean I drain it more often (which I now need to do) I also have a little jar that I try to catch the rusty water with. I have a story about an air compressor tank that was never emptied....it was made out of an old water heater tank & was difficult to drain with the drain cap being slightly up the side of the tank, it was my brother in laws & we built his garage with it, it blew up in that same garage , the bottom let go & it went through the loft floor (broke 3-2x10's) & buckled the roof, the concussion sprung the walk through door and blew out most of the windows, the corner it was sitting in....it pushed one wall out about 6" & the other wall about 4" , & blew rusty water all over his new truck. the insurance man had said that he had seen air compressors blow & land a block away, so yes....it is good to drain your air compressor regularly.

Just leave it in the tank .
When the tank is full or it finally leaks replace it

Post by: Jim on May 26, 2020, 10:24:54 pm: G'day everyone, just a question for the brains trust :)

Any hints on how you guys blow/empty the water out of your air compressors?

I probably don't do it as regularly as I should, because its a pain to get to the tap underneath but when I do let it out under pressure it blows red rusty water everywhere and stains the concrete floor.
