Aqua Matic 450-1800 Rev. A
Problems & Symptoms appearing and caused by the SEA COCK VALVE [2]:
a. The Sea Cock Valve is closed when attempting to Start the System.
System does not register feed water flow and feed water pressure when attempting to start. The SYSTEM
FAULT CODE 2 LOW PRESSURE screen appears and the System shuts down.
When the System is not in use it is good practice, for the safety of the Boat, to close the Sea Cock
Valve. Don't forget to open it prior to starting the System.
Solution: Open the Sea Cock Valve.
b. The Sea Cock Valve seal is worn or the seal adjustment is loose causing air to enter the System Feed
Line.
• System feed water pressure is low and insufficient to keep the System in operation. This section of the
Feed Line is under a vacuum condition when the System is in operation. If the valve's seal is worn or
if the seal adjustment is loose air can enter the feed line causing the System to lose pressure.
Look for air bubbles moving through the Sea Strainer, or feed line.
Solution: Change the valve seals, tighten them, or if necessary replace the valve.
3. INLET CONNECTOR [3] AS WELL AS ALL FITTINGS AND CONNECTIONS PRIOR TO THE INLET OF THE
BOOSTER PUMP [7]:
Problems & Symptoms appearing and caused by any fitting or connection in the Suction portion of the Feed
Line:
a. One or more fittings or connections in the Suction portion of the Feed Line is causing air to enter the
Feed Line.
• System feed water pressure is low and insufficient to keep the System in operation. This section of the
Feed Line is under a vacuum condition when the System is in operation.
Look for air bubbles moving through the Sea Strainer, or feed line.
Solution: Tighten any loose fitting or connection at the Inlet of the Booster Pump or prior to it
4. INLINE VACUUM / PRESSURE GAUGES [4, 6, 8, 13, 17, & 21]:
Problems & Symptoms appearing and caused by the Inline Vacuum/Pressure Gauges:
a. A Vacuum/Pressure gauge needle does not move; or does not register proper vacuum or pressure.
• The Vacuum/Pressure Gauges have a very small orifice at the bottom of the pipe fitting end. This
orifice can become plugged with debris or corrosion.
Solution: Using a small diameter wire clean the debris from the orifice.
that is allowing air to enter the feed line.
Replace worn or broken seal or O-ring at the Inlet of the Booster Pump or prior to it
that is allowing air to enter the feed line.
Check positioning of all valves at or prior to the Inlet of the Booster Pump that may
be allowing air to enter the feed line.
