I'm gluing some water pipes in my basement using Flowguard Gold medium cpvc
cement. The instructions say "allow one hour cure before pressure testing".  
Does that mean that after one hour I can just turn the water on and leave
it on? It gives no further instructions about drying time.

The cement I've used usually states the curing time relative to a
particular temperature and gives a pressure, eg ok to 120psi after 2
hours at 60F. It takes longer to cure at lower temps. So, as long as
you meet the temp spec for the 1 hour cure, and your water is normal
pressure, you are good to turn the water back on. Personally, unless
there was a critical need, I would wait an extra hour to have extra
margin.
