w yang: looks like the check valve put backward or the air will go in but won't
Rowdy Abbott: I freaking hate shrader valves waste of time pain in the ass bullcrap
Roland W: I've had a similar tank for 20 years. First thing I did was to install a
quick coupler. To fill I remove the tire-chuck hose and connect a hose from
my shop air, then open the existing valve on the manifold - it fills in
seconds. Just have to remember to close the valve before popping the shop
air hose off so air won't rush out. With your new setup you have no
pressure relief valve, correct? I do like your ball valve; wish I could
find a manifold that incorporates one. My valve now leaks.
Dexiotechnia: crap, i didnt even realize you had said this cuz i just started looking at
the thread. thats what i did. i dedicated a small hose to join both tanks.
seemed like a much better idea, and works crazy good. love my system
Jon Proce: Yeah, the compressor is regulated and has a relief valve, it will never
fill above the service pressure of the pig. I have a gauge on the tank
because the tank is used for things like filling car tires on the driveway.
If I'm out there I want to know how much pressure is in the tank and
whether or not it's enough to fill the tire.
Roman Dybala: It's not a "Schrader" valve it's SCHRADE valve. Go and look at it or google
LumpyMusic: Would like to have seen how you assembled the various plumbing fittings.
Hold still with the camera. Looks like a nice job. Explain it. Use a tripod.
Dexiotechnia: the problem that im sure you have already noticed is that you can not
disconnect the line between the compressor and extra tank because air will
escape at max psi due to a constantly open valve. this is why instead of
having your typical nipple/coupler on the hose, i put 2 nipples on either
end. what i do is fill the tanks, shut the expansion tank pressure first
via the handle valve, then cut the line pressure from the compressor.
orangehexagon: cools. thanks so much for the info.
Jacob A: uh.....no
iowawrench: I have one similar and agree 100% with you. Not a fan of how the original
fittings are. I think kjbaert has a decent idea of using the coupler in
both directions to omit the check valve. Although that would require having
a male-male fitting to hook up to an air hose handy. Your way works fine it
3zib: NIce vid! You def should have recorded the assembly of the valves as that
wold have been the best part of the vid.
Dexiotechnia: doing this means there should be zero line pressure and you can safely
disconnect and move the extra tank around if you need to go outside and
fill a tire or something. i dunno. hope this helped!
orangehexagon: thx for posting the vid. im in the same situation w a 10gal air tank that i
bought at lowe's. bummed that the schrader valve is the only way to fill
up. can u tell me roughly what kind of filling speed to expect if i
upgrade. is it a dramatic increase? or would u say it is modest?
3zib: @JonProce Its not all 1/2 but rather 1/2 and 1/4 correct?
ZZZRSC: So where's your relief valve, so you don't blow yourself into orbit if you
connect it to a system with more pressure than that Chinese tank is rated
EZRIDER327: LOL that was waste of money and time
Roman Dybala: I was wrong.
mrmotofy: Easier, simpler and cheaper to just use a double male quick connect coupler
adapter. Plug shop hose into coupler adapter, then other end of adapter
into coupler on portable tank. No expensive valves or ten extra fittings to
Charles Walter: Follow your own advice, and you will see that you have it backwards.
Dexiotechnia: its on the compressor i assume. but then why not just use the gauge on the
compressor as well. this manifold is wasting a port on a second valve. the
tank is to small to justify its own gauge because once u fill it, you know
there is 125 psi. instead of getting that high priced check valve, you
could have just used a coupler and dedicated a small hose with 2 nipples on
each end like i did to join both tanks.
kjbaert: instead of buying a check valve you should have just filled it through the
coupler. Air can flow both ways and closes automatically when you
disconnect. And was wondering why you put a shut off valve?
Dexiotechnia: this is really cool. i went out and got almost the same stuff as you did
but made a slightly different manifold. i did not put a pressure gauge on
the spare tank because my compressor came with a safety valve and 2 gauges.
having it all connected eliminates the need for an extra "t" manifold
because its all on one continuous cirquit so the gauges tell you total line
pressure between both tanks. the other thing i did different was that i put
2 couplers instead of 1 niupple 1 coupler on the tank.
