In order to drain my fresh water tank I have to open all 4 valves at the low point, thanks for everyones help...Happy Camping!!! How to drain fresh water tank? I have a question, I have a 2017 Coachman Leprechaun 260QB and I am trying to drain the fresh water tank. I have located the valves in the pictures but not sure what to open and/or close. I believe the 4 lines with the valves are my low point valves but not sure why there are 4 and should I open all of them to drain the fresh water tank? The other valves attached to the water are all open except one and I don't think I need to do anything to these to drain the tank. Any help would be appreciated, thanks.
