Had a bit of a strange occurrence Friday, getting the trailer ready for the season and discovered nothing is coming out of the hot water faucets when hooked up to the city water supply but the cold runs fine and there are no leaks. I discovered that if I open the hot water faucet in the bathroom-nothing but if I go to the kitchen and run the cold then open the hot water faucet there, it starts to flow out of the hot faucet in the bathroom- do I have an air pocket in there? Thereâ€™s no by-pass on the hot water tank. The only thing I did different this year was instead of just running all of the antifreeze out of the faucet, I drained it out of the hot water tank first. Started grilling brats and enjoying a beer so I didnâ€™t investigate further, maybe Iâ€™ll drain the hot water tank again? Has this ever happened to anyone else out there? do I have to call ghostbusters?
