direction of the fluid flow.
Has the new injector been stored for an extended period. If so, submerge
the injector in room temperature fluid for 24 hours so that the working
parts can reabsorb fluid and swell back to the proper size.
If still not clicking, do not open the upper body. Call Aquamix Customer
Service.
