Pool specialist opinion — review
- + Quality materials ensure strength and a long service life
- + Precise manufacture ensures the screw fits correctly in the impeller
- + Quick, easy fitting without professional servicing
- + Resistant to pressure, vibration and pool water chemicals
- - We recommend replacing the screw at any known sign of wear
“The impeller screw is small but essential: it holds the impeller firmly in place. If damaged or worn, it can significantly affect the counter-current unit’s performance. Water can then leak along the shaft directly into the motor, and a puddle may appear beneath it.”
