Hayward SX164DA Lateral Assembly with Center Pipe
Part # SX164DA — a replacement lateral manifold assembly designed for use in Hayward Pro Series sand filters (models S164T and S166T). This assembly includes the center stand-pipe, hub, and umbrella-style laterals to restore proper flow and filtration performance.
Key Features
- Includes umbrella-style lateral arms for even sand flow and filtration.
- Stand-pipe included for compatibility with designated filter tanks.
- Factory original replica part designed to fit Pro Series sand filters S164T and S166T.
- Ensures proper backwash and pool side operation by maintaining correct flow distribution inside the tank.
- Designed for durable service in filtration systems with sand media.
Typical Applications
This lateral assembly is used when the original assembly inside the sand filter shows signs of damage (broken laterals, cracked hub, missing stand-pipe) or when you perform a major filter service such as sand replacement. It’s compatible with the Hayward S164T and S166T Pro Series sand filters and is ideal for technicians and pool owners renovating older filter internals.
Installation & Compatibility Notes
Turn the pump off and relieve system pressure prior to servicing the filter. Drain and disassemble the filter tank and remove filter media. Extract the old lateral assembly, clean and inspect the tank interior, then install the SX164DA assembly ensuring the hub seats properly and lateral arms are correctly oriented. Re-install the sand media or other media per manufacturer instructions, reassemble the tank, and resume circulation while checking for uniform backwash flow and no leaks.
Why Choose This Assembly?
By installing the SX164DA lateral assembly, you restore proper internal flow distribution within your sand filter, preventing issues like increased pressure, backwash short-cycling, or sand leaving the tank. It’s a cost-effective way to extend the life of your existing filter without replacing the entire unit.
Maintenance Tips
- Inspect laterals when performing sand changes or when noticing pressure rise or poor backwash performance.
- Ensure the stand-pipe remains vertical and undamaged—misalignment can cause improper flow and reduce filtration efficiency.
- Replace the lateral assembly if hub cracks or laterals are worn, as damaged laterals may allow sand to bypass into the pool.
- During tank reassembly, ensure proper media level above the laterals and that no media obstructs the stand-pipe.
