What should I do if the FULTON Boiler pump runs but doesn't pump water?

If the FULTON Boiler pump runs but does not put water in the boiler, allow the system to cool down, check steam traps, and ensure return lines are not insulated. Check the return tank temperature; if it's above 82[O]C, vapor locking of the pump will occur. Inspect check valves, cleaning and replacing as needed. Replace the pump with a multi-stage centrifugal pump able to cope with 121[O]C. Check the feed water line is not blocked, clean as required.
