Default Aqua Hot Pump Manifold Corrosion - cause?

Inside of my Aqua Hot cover sits a manifold with the three zone circulation pumps. Two of the pumps and their associated copper piping are in godd condition. However the third (right hand side) pump and the copper piping going to and from the pump show excessive green discoloration and corrosion.

What would cause this? Are there anti-corrosion zincs or some type of bonding that i should look at?

Unable to upload Picture but can email.

Thank you!

Not sure what caused this issue but I would start by looking for a leak at the top of the corrosion when the system is warm and operating.

You probably have a minor leak in the zone pump. There is a "O" ring that gets hard, then leaks coolant.

You have to remove pump to replace "O" ring. Difficult job.
