Product details
The Waterway 505-1950 is a twist-lock style lateral made for Waterway ClearWater and TWM sand filters built from 2004 to present.
What it does
The lateral is part of the underdrain assembly inside a sand filter tank, collecting filtered water beneath the sand bed and directing it out of the tank, while its twist-lock design secures it in place during assembly rather than relying on a friction fit alone.
Fit and compatibility
Waterway lists the 505-1950 lateral for its ClearWater and TWM sand filter models built in the 2004 to present design, distinguishing it from earlier lateral styles used on older filter tanks of the same model lines.
Before you order
Confirm your filter model and lateral style match the ClearWater or TWM fitment above before ordering, since sand filter underdrain parts vary between tank generations. It is sold individually.
