I have the manual thanks to Ed but after looking thru it I did not see any mention of possible issues. dumb question what does the low point valves do and how should I use them when necessary.

Typically the low point drains are used during winterizing to make sure antifreeze is pumped everywhere in the plumbing (open them up last).
I also use them to drain the tank: Simply using the tank drain can take hours to empty the water tank. I turn on the pump and open the low point drains (and/or the outside shower). This lets the pump run full steam and can empty the water tank in 10-20 minutes.
