has to be ripped apart before it can be rebuilt

so I figured out the water pump valve yesterday it is a winterizing hose, but I was to busy looking for a way to run electrical I didn't have time to actualy grab hoses trying to follow them till last night.  the other two valves remain a mistery....  unless they are just isolation valves , but then the only thing I could see them isolating is the outdoor shower.  I think I am going to break out the endo scope and see if I can follow the lines.
