Question Travel trailer water drains

[Salty Bob]

I own a Starcraft Autumn Ridge travel trailer and I don't know where the hot and cold water drains are. The trailer is at my brothers and he said the only drain valve is marked low water drain and white in color. Is ther other drains and where are they? My old trailer had red and blue capped lines. Thanks

Drain water heater at the unit plug. Drop low point drains. Open all faucets. Use antifreeze in lines or blow them out. When done disconnect water pump on inlet and outlet sides.
