John (et al)
I have one of HF's auto drain kits. I'm of mixed opinion about it, so I'll
just tell what I know...
The 250psi nylon hose supplied burst at 135psi. (It burst adjacent to the
connectors, so it's a system problem, not a hose problem) I have replumbed
the entire thing with soft copper pipe, which was difficult to do as one of
the fittings has an odd thread. So, it can be made safe and leak tight. For
about $10 more than the original $11.
Connecting the signal line requires tapping into the pump-to-receiver line.
Originally in my compressor, there was a plastic (much thicker walls) hose
running from that line to the pressure bleed. I tried to tap into that, and
ended up spoiling the original hose. I wish I'd just caredully set it aside
in case of warranty issues... As I said before, the system is entirely
copper now.
The drain time is inadequate, IMHO. It does drain some water, but doesn't
drain it entirely off. Rather than just see a half-second squirt of water, I
would like to hear a few seconds of air as well, so I know it's done its
job.
It augments draining the tank daily very well. It's inadequate as a complete
solution. If I were to do it again, I think I'd just make a copper line from
the base of the tank running out to a ball valve conveniently placed.
For reference, my compressor is a CH "Quadzilla", 60 gallons at 135psi.
