maker runs well making water
for about 5 minutes. Then the vane pump
goes quiter but all outputs ok but 10% less of product water flow. Then the vane pump
starts vibrating and shaking like it is going to explode or rip itself off the bulkhead. I then shut it down as I donít want to know the conclusion if I let it keep going. Why is it so? I have changed filters to no effect and there are no alarms on my MPC controller.
