Sticking Fill Whip Valve?
- I was filling tanks recently, changing tanks while the compressor was running. I connected an empty tank and opened the tank and the whip valves. This is where the fill needle slides down to whatever pressure is left in the empty tank. I looked away for a second or two and looked back to see that the needle was at 3000 psi. The empty tank was one of my vintage 1800 psi ones so, I snapped to attention and quickly turned off the compressor. Twisting the whip and tank valves had no affect... The needle stayed at 3000 psi until I close the valves, bled off the pressure, and disconnected the fill whip. I then opened the fill whip valve and the pressure bled out normally. Trying again, everything worked fine and the tank filled without any problem. This happened once while filling tanks last Summer, too.
- Is it possible my fill whip valve seat could stick closed even though it was twisted open?
- After writing this description, I'm wondering if maybe it was the TANK valve... I don't remember if it was this same tank when it happened last Summer.
