To the question you saved 'til last.... yeah, give it a f' in good whack, but make sure you're stood in the next parking lot when it kicks off. Buy another one, they're available from a few oulets, but remember to drain the tank before you unscrew it.....good luckI hear and smell propane when I turn on the valve. I had the tank filled yesterday. I took off the plastic cover to uncover the exterior valves and discovered the leak is on the first valve. There was no leak last fall. Is there a pressure switch inside the valve that could be stuck? If I wrap on it with a small tool might it unstick?
