15 years ago
hose with a tire chuck. It has a tire valve to fill it, a gauge, a
shutoff valve and an over-presure relief valve all mounted in a brass
manifold. The tire valve and shut-off are built into one combination
assembly and are also an integral part of the manifold.
When I first pressurized it, I filled it to 100 PSI, and let it sit for a
day, at which point it had bled down to ~85 PSI. As best I could tell,
the over-pressure valve was leaking, and it is pretty much integral with
the manifold. I complained to the manufacturer, and they sent me a whole
new manifold. I installed that a couple days ago, and it leaks even
worse. I haven't had time to figure out where the leak is this time, but
I can hear it. I'm going to try soapy water next to try to pin down the
I have a couple questions:
1) For a decent system, how well should it hold pressure? I would think
that losing a PSI a week might be more reasonable.
2) Can anyone recommend a decent source for a manifold, over-pressure
relief and tire valve filling adapter? The tank has a 3/4" NPT opening,
and if I can't fix this one, I'll just replace it with something other
than Chinese garbage. The tank itself is very nice, but it's pretty
obvious the accessories are junk.
