Howdy,
2016 Chaparral 29mks
I drained the tanks and I blew out the lines (At least twice). I blew out the black tank flush lines and poured plenty of RV antifreeze in all the P-traps. I removed the drain plug on the hot water heater and blew it out too. My concern is, I can still hear gurgling while blowing out the hot water heater and the pump. When I turn on the pump, nothing makes it to the faucets, but I can hear the gurgling. IF the water builds in the pump, it could freeze and kill the pump. I don't want to use anti-freeze in the lines. Is the residual water a problem?
We will finally get below freezing this week. Here is a pic of my CB. Any suggestions will be greatly appreciated.
