What to do if my HydraMaster Vacuum Cleaner system will not prime?

If the system won't prime, consider these possibilities: * Faulty check valves in the chemical pump: Remove and inspect the valves, cleaning or replacing them as needed. * A faulty chemical pump diaphragm: Remove and inspect, replacing if necessary. * A faulty check valve in the high-pressure pump: Remove and inspect the valve, cleaning or replacing as necessary. * A clogged filter on the feed line in the chemical jug: Inspect and clean it. * A loose, pinched, or damaged feed line from the chemical jug: Inspect and repair it. * A faulty chemical selector valve: Inspect the valve for leaks between ports and replace if necessary.
