All of the flow indicators on one of my manifolds are stuck. No matter how I adjust the flow, they don't budge. Other two manifolds are just fine.

 

Any easy way to free them?

You may need to isolate the manifold, depressurise the manifold and take the flow meters off and clean them.

 

This is what they look like internally.

 

A little valve is pushed by a water flow against a spring
