Genuine Hayward® product, supplied by an authorised Hayward dealer
Overview
SP1424 wall inlets have a white body and grate. An internal spinner valve disc and O-ring, adjusted through the centre hole in the grate, give a full range of flow adjustment, line testing and winterising. SP1425 floor inlets install in the pool floor for uniform, high-velocity 360° water distribution: the top diffuser plate is stationary and directs flow away from the floor to help prevent staining or erosion, with tamper-resistant flow settings.
