What horsepower tells you
Horsepower describes a power rating. It does not tell you exactly how much water will move through your installed pool system. The pump design and system resistance also matter.
A request for a 1 HP or 2 HP pump is a starting point for a discussion. It is not a complete specification for a new pool or a replacement.
Give the supplier useful information
Send the pool dimensions, average depth, pipe sizes and details of the filter and other connected equipment. For an existing pool, include the current pump model and any known flow or pressure readings.
If you have a drawing, share it. Even a clear layout with pipe lengths and equipment positions can help an installer prepare a more informed selection.
Compare models fairly
Ask for flow at the same operating condition, electrical input, connection dimensions and the proposed installation arrangement. Make sure quantities and included accessories are clear.
Do not compare one model at its maximum advertised flow with another at a realistic system condition. Ask for equivalent information in both quotations.
Keep the decision on record
Ask the supplier or installer to state the basis of the selection. Save the datasheet and pump curve with your purchase documents. When enquiring about COREX Max Flow pumps, describe the pool system as well as any preferred horsepower.
