So the last 2 batches I've done its taken my turkey fryer forever to get water to boil. Finally this last time, my dad had his laying around and we swapped it out and it worked twice as fast. As soon as I hooked it up and fired it up, I could immediately hear the difference. With in a matter of minutes I had boiling water. I'm not sure what is wrong with mine? We used the same propane tank so it's not that. Anyone have any ideas?
