An incredible feature list, high-quality components, plus amazing performance. The four-chamber high-volume design, driven by a heavy-duty motor produces flow rates of 3.0GPM or 3.5 GPM, capable of self-priming up to 6 vertical feet, and can run dry, making it the price-to-performance leader. This pump also offers a variety of easy-connect fittings and filters. - Page 5 1 electrical cut off switch 1 fuse 1 screwdriver 1 strong cutting implement for tubing (if desired)Teflon tape or sealant Setup 1.

- Page 10 About the Bypass Valve The pump uses a spring-loaded bypass valve to maintain smooth performance as water demands rise and fall. When a faucet is turned on the pump is providing full water flow, so the bypass valve is closed. But when there is little to no water demand, the bypass valve opens to allow water to flow back from the outlet side to the inlet side, keeping a steady flow of water within the pump with almost no cycling.
- Page 11 ABOUT THE BYPASS Please consult a professional technician in case the bypass needs adjustment. Improper adjustment of the bypass may damage the pump. The bypass comes preset for optimal operation of the pump. If your application calls for a different setting for the bypass, you may change it yourself. Carefully tighten the screw to increase or loosen the screw to decrease the minimum operating pressure of the bypass.
