| Use your shower line
Gary,
After you bypass and drain your water heater, you should fill the remaining system with RV antifreeze.
The threaded fitting on the inlet of your water pump is a match to the threaded fitting on the handheld shower hose that came with your trailer. Attach on end to the pump inlet and use the hose as a pickup into the antifreeze bottle. There is no need to buy anything extra from a hardware store.
Draining the entire system ahead of time is a good idea too as it will minimize the chance that a corner somewhere will be water filled.
Don't forget the drain traps.
Jim
