Pentair lateral / manifold arm for Triton/Tagelus/Poseidon 60-80 and Cristal-Flo 22–26" - R302404

Pentair lateral / manifold arm for Triton/Tagelus/Poseidon 60-80 and Cristal-Flo 22–26″ – R302404

The Pentair R302404 lateral (manifold arm) is a replacement collector used in the lower manifold of selected Pentair sand filters. It helps distribute and collect water evenly through the filter bed while retaining the filter media inside the tank. Replacing a worn or cracked lateral is essential if you notice sand returning to the pool, reduced water clarity or irregular filter pressure readings.

• Replacement lateral / manifold arm for the lower collector assembly.
• Compatible with multiple Pentair platforms, including Triton, Tagelus and Poseidon 60–80.
• Also used on Azur/NM and Cristal-Flo 22″/24″/26″ (160 m series) configurations.

What this lateral does

Laterals sit at the bottom of the filter tank and form the “collector” that gathers filtered water and routes it back to the return line. The slotted design holds back sand or glass media while allowing clean water through. If a lateral breaks, media can bypass the filtration stage and return to the pool, often causing cloudy water and visible sand on the pool floor.

Compatibility and selection tips

This part reference is commonly associated with Triton, Tagelus and Poseidon 60–80 filters and is also listed for Azur/NM and Cristal-Flo 22″, 24″ and 26″ (160 m) variants that use the same manifold format. Always confirm your exact filter model and diameter, and compare the existing lateral connection and shape before ordering. If one lateral has failed, it is recommended to inspect the full manifold hub and standpipe for cracks or stress marks.

Installation notes

Switch off the pump and fully depressurise the filter. Drain the tank to a safe level and access the manifold by removing the top assembly as required. Replace the damaged lateral, ensure correct seating, and reassemble with clean sealing surfaces. After refilling with the correct media, backwash and rinse before returning to filtration.
