Hayward SX242MA1 Replacement Lateral Assembly

The Hayward SX242MA1 is an internal lateral and underdrain assembly originally used in compatible Hayward S244S side-mount sand filters. It sits beneath the sand bed and helps distribute water evenly through the filter while keeping filter sand inside the tank.

Because the original SX242MA1 is no longer available, Hayward now directs customers to the updated SX242MA1S lateral holder assembly. The replacement may look different from the original component, but it is intended to perform the same essential filtration and underdrain function.

Compatibility and Fitment

Hayward lists SX242MA1S as the replacement for discontinued SX242MA1. It is designed to replace the original lateral assembly used in its specified compatible filter application.

Do not select this part based only on filter diameter or appearance. Confirm the complete filter model and compare the existing standpipe and internal connection before installation.

Installation Guidance
  1. Turn off the pump and disconnect power to the filtration system.
  2. Relieve all pressure from the filter before opening the tank.
  3. Remove the filter sand as necessary to access the underdrain assembly.
  4. Inspect the standpipe, hub connection, laterals, and tank interior for additional damage.
  5. Install the replacement according to the filter manufacturer’s service instructions.
  6. Refill with the correct type and quantity of filter sand before restarting the system.
Pool filters operate under pressure. Installation should be completed by a qualified pool professional when the owner is unfamiliar with pressure-filter service.
