Welcome to the forums.

I'm lost..... you installed three pumps for ......... three zones ?
If yes..... why are you using valves.
Typically it's one pump and a valve for each zone.
When the zone valve opens... the one pump runs.

If you have three zones with three pumps.... you don't use zone valves.
You would check/anti flo valves.

We need to know more about what you have.
Pictures can be a big help..... How to insert pictures.
