Any Ideas?

We operate a large (seasonal) facility with "old" Plumbing. Yes, some copper has been replaced with PVC however every year when we open for business, we always have leaks. We blow out the lines each year but to little avail. Any suggestions would be greatly appreciated.

A couple of thoughts.
1. After you blow out lines do you keep the valves open?
2. Perhaps your water shut off is letting water bypass, even if it is very small amount after a while it could fill your pipes.
3. Are your lines pitched towards the open valves?
