Common Concerns Answered
Does this pump require priming?
Yes, the Rule 3700 GPH pump is not self-priming and requires initial manual priming before operation. Ensure the pump body and intake line are filled with water to initiate flow.
Can this pump be used for a washdown system?
No, this pump is designed for high-volume water transfer at low pressure and is not suitable for washdown applications that require significant pressure. Its primary function is rapid water movement, not pressure generation.
Will this pump be noisy?
While capable of high volume, noise can occur if the pump is not properly mounted or if cavitation takes place. Secure mounting and ensuring a consistent water supply will minimize operational noise.
Frequently Asked Questions
Is the Rule 3700 GPH pump self-priming?
No, the Rule 3700 GPH pump is not self-priming and requires initial manual priming before operation.
What is the maximum pressure this pump can deliver?
This pump is designed for low-pressure applications and focuses on high volume output, not maximum pressure delivery. Specific pressure ratings are not a primary specification for this model.
What size hose is compatible with the Rule 3700 GPH pump?
The Rule 3700 GPH pump features 1-1/2" (38mm) inlet and discharge ports, making it compatible with hoses of the same internal diameter for optimal flow.
Where should the Rule 3700 GPH pump be mounted?
This pump must be mounted below the waterline to ensure it can draw water effectively and operate without the need for self-priming beyond the initial fill.
What is the warranty period for the Rule 3700 GPH pump?
The Rule 3700 GPH pump comes with a 3-year manufacturer's warranty.
