I suspect I have a bad BBQ LP regulator, just not sure.

Only about the fourth tank used since new. I understand they go bad.

With the tank, regulator and hose removed and away from the grill I
turned the tank with the regulator and hose in place on and no
indication of gas/smell.

I close the tank, removed the regulator and opened to tank valve,
still no smell and I figured to tank will not allow gas out without
the regulator nipple piece in the tank valve.

I was able to blow air through the regulator and hose ( correct flow
direction ). I don't know.

Do they stick open / closed? Should air travel through the regulator
if I buy the new one (before install) ?

I don't guess the tank valve would be bad. This started when the
exchange tank went on, but only on the second use of the grill.

The burners are in good/clean shape, so I foresee a regulator
