Hayward SPX1705C Impeller - 1/2 HP

What This Part Is Used For
The Hayward SPX1705C is a 1/2 HP impeller used in compatible Hayward pump wet ends. It installs on the motor shaft and creates the water movement that feeds the filter and returns. This part lives inside the pump housing behind the strainer section.

Why This Part Matters
When an impeller wears down or gets damaged, flow drops and the system can struggle to skim and filter effectively. Low circulation can also cause heater issues and inconsistent chemical mixing. Replacing the correct 1/2 HP impeller restores normal turnover and pressure behavior.

Installation and Fitment Guidance
