How It Works

Pre-Flush

1. Borescope: Heat Exchanger, Cooler (Trans) other systems when Zinc and or visual openings are accessible and possible.
2. Pressure test Heat Exchanger for loss of pressure and leaks. If an expansion tank (recovery bottle) is in place, check for proper connections, obstructions and for leaks.
3. Check Coolant level, color and test for effectiveness; check overflow level in the tank.
4. Visual and Borescope Raw Water Pump Impeller. Checking for color change of the original color black impeller; Flexibility, chips, cracks, and Borescope down the fins.
5. Check Sea Cock Valve for operational and functional. Note: A Sea Cock Valve in a closed position can still allow for seawater seepage if the valve is compromised.
6. Check Sea Strainer for grass build-up and clarity of cylinder.
7. Check Zincs for wear and leaks.
8. Check all Hoses and Hose Clamps and inspect for double clamps where necessary.
9. Start Engines checking for issues that could prevent doing a flush. While the engine is running, check the hull outflow exhaust/water stream and color of smoke if any.

Flush Procedures

1. Setting up the equipment prior to flush.
2. Boat protection: All boat surface areas are protected by waterproof tarps.
3. Plumbing prior to flush.
4. The Flushing unit: We first run fresh water through the system to check for leaks prior to adding the ​Barnacle Buster descaler. Our exceptional flushing rate is over 1,200 gallons per hour for a minimum of two hours, reversing the flow after one hour so as not to have any large particles trapped in any direction. During the first ten minutes of the flushing procedure with the biodegradable descaler, we can see the change in color and odor as a result of the descalers’ effectiveness to breakdown the calcium deposits. As time goes on during the two-hour flush, one can see the intensity of the descaling results. The white bag is used to filter particles such as broken impellers, zincs, shells, incrustations and other foreign matter that should not be in the system.
5. Flushing all the systems with fresh water.
6. Boroscope the results of the flush.
