When a sand filter is opened for service, replacing worn laterals can be the difference between a routine repair and recurring filtration problems. This Hayward lateral 10-pack is designed for select Pro Series sand filters, including S180T, S210S, S220T, S230, and S245T applications, helping restore dependable performance inside the tank. The lateral assembly plays a critical role in collecting filtered water while keeping sand media contained. Cracked, clogged, or brittle laterals may allow sand to return through the pool returns or reduce overall flow efficiency. This pack is well suited for planned maintenance, filter rebuilds, or corrective repairs where multiple laterals need attention at the same time. 10-pack replacement for select Hayward Pro Series sand filters Supports clean return flow and media retention Ideal for filter rebuilds or sand-change maintenance Helps resolve damaged or aging lateral components Part SX240DNPAK10 for accurate replacement matching
