Testing Wash Down Installation
7
1. The wash down pump should operate with the on/off switch. The wash down pump will automatically shut
off once it has built up approximately 40 psi in the outlet hose.
2. Check all hose and fitting connections to be sure there are no water leaks. Check the routing of all hoses
to make sure they are away from moving parts and high heat sources, and secured from sharp objects or
edges and are not kinked or pinched in any way.
3. Adjust the water temperature by turning the corresponding valve for the desired water temperature.
Poor Water Pressure
1. Make sure water source has water.
2. Check on/off switch and condition of fuse to pump.
3. Check the routing of all hoses to be sure they are not kinked or pinched in any way.
4. The wash down kit may be equipped with a strainer that can become clogged. To clean strainer, remove
screw-on top and inspect for debris. IMPORTANT: Do not remove screens. In many cases the debris can
simply be scraped off or can be back-flushed with water pressure.
5. Remove spray head and check for debris.
6. Pump pressure can be tested using an auxiliary hose from input side of the pump into a bucket of water.
NOTE: If anti-freeze has been drawn into the system, be sure to flush the system completely before using.
1. The wash down pump and all hoses should be completely drained of water to prevent damage. This can be
easily accomplished by removing the inlet and outlet hoses from the wash down pump (be sure to keep the
inlet hose above the water line of the boat to prevent flooding the bilge). With the hoses disconnected
momentarily turn the pump on to purge any trapped water then remove the wash down nozzle from the outlet
hose and blow back through the hose to purge any water from it. Once the water is removed reattach the
inlet and outlet hoses to the wash down pump.
2. RV/MARINE anti-freeze can be drawn into the wash down system by removing the hose from the water
source and then inserting it into a container of anti-freeze. Turn on the wash down pump until anti-freeze
sprays out of the shower head.
