Safety Information
Always prioritize safety during installation and operation. This pump is equipped with a built-in automatic thermal overload protection feature to prevent motor damage by disconnecting the circuit if the unit overheats. The pump can also run dry for up to 10 minutes without damage. Ensure all electrical connections are secure and meet local codes.
Image: Safety features include thermal protection, which automatically stops the motor if the surface temperature reaches 194°F (90°C), and the ability to run dry for up to 10 minutes without damage.
Setup
The pump features a self-priming lift of 9.8 feet (3 meters) for flexible installation. It is fitted with 1/2" NPT pipe threads, allowing for connection with various standard connectors. Ensure the strainer is firmly tightened before operation.
- Firmly tighten the strainer: Attach the included strainer to the pump's inlet to prevent debris from entering.
- Install barbed hose adaptors: Install the barbed hose adaptors to the threaded MNPT on the pump.
- Install hose: Connect your water hose to the barbed adaptors.

Operating Instructions
This pump operates on an on-demand system with an automatic pressure switch. When a faucet is opened, the pump activates to provide water. When the faucet is closed, the pump shuts off automatically at 70 PSI.
- Automatic Pressure Switch: The pump features a built-in automatic pressure switch that starts and stops the pump on demand for seamless water flow.
- Pressure Adjustment: The pressure switch is preset to a 70 PSI cut-off. To adjust, open the top cover and turn the screw. Turning clockwise increases pressure (adjustable range: 40-80 PSI), while turning counter-clockwise decreases it.
- Smart Bypass: The integrated smart bypass prevents rapid cycling noise, contributing to quieter operation, especially during low flow usage.

Maintenance
The DC HOUSE pump is engineered with durable and corrosion-resistant components for consistent performance and longevity.
- Diaphragm: Engineered with a long-lasting Santoprene diaphragm for consistent performance.
- Housings: Made from Nylon/Polypropylene for durability.
- Valves/Seals: Constructed from EPDM/Viton for reliable sealing.
- Sealed Gasket: Prevents water from leaking into the motor, enhancing the pump's lifespan.
- Screws: Stainless steel screws are used for corrosion resistance.
- Motor: Features a pure copper motor for durability, efficiency, and excellent conductivity.
Regularly inspect the strainer for debris and clean as necessary to maintain optimal flow. Ensure all connections remain tight to prevent leaks.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump runs but no water flows or low flow | Clogged strainer, air in system, kinked hose, blockage in faucet/line. | Clean strainer. Bleed air from system. Check hoses for kinks. Inspect faucets/lines for blockages. |
| Pump cycles on and off frequently (rapid cycling) | Small leak in system, pressure switch setting too sensitive, bypass not functioning optimally. | Check for leaks in plumbing. Adjust pressure switch (increase cut-off pressure slightly). Ensure bypass is clear. |
| Pump does not turn on | No power, faulty wiring, pressure switch malfunction, thermal overload activated. | Check power supply and connections. Verify wiring. Inspect pressure switch. Allow pump to cool if thermal protection activated. |
| Excessive noise during operation | Vibration, air in system, loose mounting. | Ensure pump is securely mounted on its rubber base. Bleed air from system. |
