As I’ve mentioned before, you may want to check that an option to minimize water hammer (link) is turned ON, other than that it sounds like you have your master valve/pump enabled correctly (otherwise it would not work).
You’ll want to find a good PWS station near you, here is some description (link) on how to do so via weather underground if existing stations in your area do not have a good rainfall data.
Good job! Make sure to post final pictures after cleanup 
Others in your situation may also appreciate if you could provide an estimate on how much your renovation has cost (if you don’t mind sharing).
Cheers,
