Setup and Installation
Proper installation is crucial for the pump's performance and longevity. Follow these steps carefully:
- Mounting: Securely mount the pump in a stable, dry location. Ensure it is protected from weather elements and freezing temperatures. The pump can self-prime up to 10 feet vertically and 155 feet horizontally.
- Inlet Connection: Connect the included 50 mesh strainer to the inlet port of the pump. This prevents debris from entering and damaging the pump. Then, connect your water source hose to the strainer using the quick-connect ports.
- Outlet Connection: Connect your output hose to the outlet port of the pump using the quick-connect ports. Ensure all connections are secure and leak-free.
- Quick Connect Procedure:
- Push out the clicks on the quick-connect fitting.
- Push the connector firmly into the pump's port.
- Push firmly until the clicks lock into place.
- Electrical Connection: Plug the pump into a standard 110V AC power outlet. Ensure the outlet is properly grounded.

Operating Instructions
Once installed, operating your CrestWave pump is straightforward:
- Initial Start-up: Ensure all connections are tight and the water source is open. Plug in the pump. The pump will begin to prime itself.
- Automatic Operation: The pump features an automatic ON/OFF pressure switch. It will turn on when water demand is detected (e.g., opening a faucet) and turn off when the demand stops and system pressure reaches the set point.
- Pressure Adjustment: The pump's pressure switch is adjustable from 20-70 PSI. To adjust the pressure:
- Locate the pressure adjustment screw on the pump.
- Use a screwdriver to rotate the screw.
- Rotate clockwise to increase pressure.
- Rotate counter-clockwise to decrease pressure.
- Quiet Operation: The pump is designed to operate at a noise level of ≤65dB, providing a comfortable user experience.

Maintenance
Regular maintenance ensures optimal performance and extends the life of your pump.
- Strainer Cleaning: Periodically inspect and clean the 50 mesh strainer to prevent blockages and maintain flow rate. Disconnect power before cleaning.
- Leak Checks: Regularly check all connections for leaks. Tighten fittings as necessary. The pump features enhanced seal technology to reduce leakage risks.
- Winterization: If the pump is used in an area subject to freezing temperatures, it must be drained completely to prevent damage. Disconnect the inlet and outlet hoses and allow all water to exit the pump. Store in a warm, dry place if possible.
- General Inspection: Inspect the power cord for any damage. Ensure the pump is free from dirt and debris.
Troubleshooting
Refer to this section for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on | No power; tripped circuit breaker; faulty wiring; pump in dry-run protection mode. | Check power connection and circuit breaker. Inspect wiring. Ensure water supply is available and prime the pump if necessary. |
| Low flow or pressure | Clogged strainer; air in the system; kinked hoses; incorrect pressure setting. | Clean the strainer. Bleed air from the system. Straighten hoses. Adjust pressure setting (refer to Operating Instructions). |
| Pump runs continuously | Leak in the system; faulty pressure switch; insufficient water supply. | Check all plumbing for leaks and repair. Ensure adequate water supply. If issue persists, contact support. |
| Water leaks from pump | Loose connections; damaged seals. | Tighten all quick-connect fittings and hose clamps. If seals are damaged, contact support for replacement parts. |
| Excessive noise | Air in the system; pump not securely mounted; debris in pump. | Bleed air from the system. Ensure pump is securely mounted on a stable surface. Check for and remove any debris. |
