Automatic Tank Drain

[joshs1ofakindxj]

I thought I saw someone post a link to an air tank drain valve that automatically dumps water when it fills. No manual work. I think it was around $50. Was I dreaming or do I just suck that bad at searching?

Maybe it was this.

I happened to have the harbor freight screen open on another window when i saw this thread... Automatic Compressor Drain Kit

I think DieselBob is on it.

man2112, I was looking at that and read some reviews and write-ups and it seems like it needs a lot of tweaking and BS.

Does anyone have any review of these? Do they work well? Can I connect the drain lines of the tanks with a cross-over pipe to just one automatic valve to save on cost?

If you want to really save on cost, lay under your truck and drain them manually. And while your down there, do a visual inspection of everything possible.

Do not connect your tank drains together.

Do not connect your tank drains together.

Why? Do the tanks have different pressures?

Had use of one back in the 70's......they work good in the nice weather but freeze in the winter and let air out if you dont put a flame by it.....took it off the truck it came on.....we always open drain valve at end of days work,closed it in the morning....DAS

The tanks fill in a particular way so that the moisture is mostly contained in one tank(wet tank), then your system draws from the dry tank, to protect your system components.

If you interconnected them at the bottom, you'll defeat this systems well proven design.

Get some cable operated drains, if bending over is a problem. You still should look under your truck often, for situational awareness. ie, hows your Parking brake shoe condition and are all 3 springs there. Like how many leaks do you have, and where. Like is there oil or BFS leaking on the inside front duels, or is your PTO leaking ect...

It hurts me to bend or kneel, and I'd still rather get a tarp or creeper, and lay under my truck, to drain my tanks, and inspect things daily. Some days I simply lean down and crack the valves. I also add a 2-3" long 1/4 bolt, to all my valve handles, to make it easier to operate.

Thanks for the explanation. I will go with the chain operated I think.

Bending over isn't much of a problem for me but I plan on driving this truck fairly often once I do a few more modifications. I won't always be dressed properly to be crawling under the truck, which I do enjoy doing to study things.
