Propane leakdown
I put a pressure gauge inline between the tank and regulator for the first time ever. After I shut the gas off the pressure on the gauge will drop overnight from green (pressurized) to the red (meani...

So, it is not normal for the pressure to leak down overnight?
This is not a red/green indicator as on a two-tank system, it is a dial, green range is full tank, as tank pressure lowers the dial moves into a red colored background (not unlike the red in your rpm tachometer).
The dial measures psi and shows this with a needle.
I should have explained this more clearly at first.
Nylog is the stuff. It is cheap insurance for sealing things. It is used in the refrigeration industry as gospel. Use it on all your propane fittings from now on. Teflon tapes are of the past now unless you need to lubricate the threads..
I did not use Nylog on the tank fitting, possible that is a leak? I will go bubble check that and nylong it and retest.
**also, this tank I have had sitting in garage for 6+ months so I do not suspect it is leaking when closed.
Temps change very little overnight here during summer, not enough to swing psi this much.
If this is not normal then I will assume it is the pigtail, which is the only used part in the system other than the heater.
I guess you are testing the fittings/pigtail between the Tank connection and the INPUT of the LP regulator? If so, either the Pigtail is leaking at the crimp or your gauge has an inherent leak. Pigtails can leak when they get older at the crimp ring that secures the rubber to the fittings. Doug
