this drain kit, is it supposed to drain your tank automatically or do you
still have to drain it a bit to release the condensation?
It may be a stupid question but if I don't ask then how would I know?
Hey Ted & Al
I installed this kit about 2 years ago. works great no real trick to
installing just make
sure you cut the correct line to put the tee in. you need a small
tubing cutter and do your self a favor and shitcan the nylon tubing and
the tee in the kit and replace with something of higher quality the
valve works well and yes Al it automatically
opens the drain momentarly? when the compresser starts and stops I also
think its a good idea to install a manual drain valve also and open it
every now and then, say monthly just to be sure the auto drain is
Just to clarify it's not clear on the website the 100 psi max is for
the nylon/plastic line from the drain to the tee it
should never get that high. the tee is installed in the dump line which
is only under pressure when the compresser starts or stops. other wise
the drain would be open the whole time it's running.
That [http://www.paragoncode.com/shop/compressor /] was a great site. I've
had one of those HF auto drain kits for a year or more because I could NOT
figure out how to connect it to my SEARS compressor - this page answered
But he did not use the HF device. Anyone actually se the HF device and get
According to the web page he did indeed use the Harbor Freight product. No
matter - the Harbor Freight sniffers I've seen in the store are exactly like
what is pictured in the link below and would install exactly the same way.
It sure does look like the HF device to me.
What are you confused about having looked at the site? I looked at it and
it's well documented and you should be able to install your HF device just
as described on the site.
It was one of them. HF sells two differently numbered kits. I don't know
why; I've used both and they are equivalent to each other.
To address another question someone raised in this thread -- I am not
absolutely positive -- but I believe the 100 psi spec is for the plastic
tubing that connects the unloader line to the valve. It is indeed pretty
wimpy and can burst under pressure, especially if it gets too hot. Still,
my compressor switches off at 120 psi, and the auto-drainer has been
working *almost* flawlessly since 2001.
Once when I had been using a pneumatic sander for a long time, the line
popped. The plastic had gotten soft from all the heat and blew a hole. It
was an easy fix, but annoying.
To avoid this possibility, you can replace the plastic tubing with
standard 1/4" copper line. I did this for the compressor at my friend
Rob's gas station. It works very well. We had to cut the nipple off the
fitting where the unloader line attaches to the valve, though. We also
had to replace the nut and the tee with standard compression fittings. As
you can imagine, a gas station compressor gets a lot of use. Rob's has
been problem-free for a couple years so far.
