This is my first winter with this trailer. Ive drained the waste tanks and fresh water tank and used the onboard pump to pump all the water out I can. What else do I need to do to winterize the plumbing and pump? Im sure there is still some water remaining in the pump, lines and water heater.thanks

Don't forget to bypass the water heater if your trailer has a bypass line, otherwise you'll pump several gallons into the WH for no reason. Don't confuse antifreeze, make sure it's RV antifreeze the other stuff will poison you. When I winterize our camper, I like to pump the lines with the antifreeze, then connect an air compressor to the city water connection (making sure the pressure is 40psi or less) and blow the antifreeze into the drains. Two reasons, first it makes sure there's no water trapped in the city water connection that could freeze; second the antifreeze blown out of the lines now protects the pee-traps in the drains.
