I?m winterizing my trailer for the first time. I?ve drained the water from the holding tank and run the pump as per the instructions. I?ve drained the hot water heater as well. Now I have 30lbs of air blowing in. When I started that, the water heater sputtered out some more water. Now nothing is really coming out, but I can hear bubbling from in there.
Should I be concerned? Do I keep blowing air in until this stops? Is this normal and I should just move on?
