A bypass is useful in winterizing the unit—if using RV AF it gets pricey to have to put 6-12 gallons in it, just simpler to take it out of the circuit, then drain it.
There should be low-point drain valves for both hot and cold water systems, you just haven’t found them yet.
If you go thru a hard winter with it in storage without a good effort at winterizing, you will quickly find out next spring why such an effort was needed.
