The Jandy R0745400 Lateral & Standpipe Assembly is a genuine OEM replacement designed for the SFTM22-1.5 top-mount sand filter series. This assembly includes the internal standpipe and surrounding laterals that distribute and collect filtered water during normal and backwash modes. Over time, cracked or broken laterals or damaged standpipe can lead to sand leakage or poor filtration. Installing this assembly restores proper flow dynamics, sand containment, and filter efficiency—helping maintain optimal pool clarity and performance.
Highlights
-
Complete Internal Distribution Assembly: Includes the upright standpipe and full radial set of laterals, providing key components to rebuild the filter’s internal flow network.
-
OEM Fit for SFTM22-1.5 Filters: Specifically engineered for the SFTM22-1.5 model, ensuring precise dimensions and compatibility without modification.
-
Restores Sand-Containment & Backwash Performance: Corrects issues like sand in the pool, premature backwash cycles, or pressure spikes caused by damaged internals.
-
Durable Material Construction: Manufactured to withstand typical pool operating conditions, including pressure cycling, temperature variation, and chemical exposure.
-
Cost-Effective Maintenance Solution: Replacing the internal assembly prevents the need to replace the entire filter tank when internal parts wear out.
