The DW and I are looking to camp year round. In Virginia, you can usually find several weekends throughout the winter that are not that cold. In the past, I have drained the hot water heater, turned the hot water bypass and blew out the lines including the black water flush. Only put anti-freeze in the p-traps and toilet bowl. With the new rig, I have to unload half the basement and remove a panel to get to the hot water bypass. Not a big deal, but could be a pain if we camp 7-8 times over the winter.
Question is: If I drain the hot water heater and blow out the lines (checking to ensure hot water heater tank is empty), is there any need to use the bypass? My gut says no, but I look for the vast knowledge of other members. Thank you in advance for your replies.
