Zodiac – Quarter-turn strainer baskets D400 (x2) – R0674700

This genuine Zodiac replacement kit contains two quarter-turn strainer baskets designed for use with Zodiac D400 series sand filter systems. The strainer baskets, also referred to as lateral collectors or laterals, are the slotted finger-like components fitted at the base of a sand filter’s central standpipe. Their primary function is to retain the filter sand inside the tank while allowing clean, filtered water to pass freely through to the return line. Without properly functioning laterals, sand can escape into the pool, compromising water clarity and potentially damaging pool equipment downstream.

The quarter-turn locking mechanism is a key design feature of this kit. Unlike traditional screw-in laterals that can seize or crack under repeated thermal expansion and contraction, these laterals engage and disengage with a simple 90-degree rotation. This makes servicing the filter — such as replacing sand or inspecting the underdrain assembly — significantly faster and less likely to result in accidental breakage during maintenance. The fit is positive and secure, eliminating concerns about laterals loosening during normal filtration operation.

Technical characteristics and compatibility

These laterals are specifically dimensioned for the Zodiac D400 filter body, which corresponds to a 400 mm diameter tank. The D400 is a mid-range sand filter popular in residential pool installations. The part reference R0674700 is confirmed in Zodiac’s official 2020 catalogue and is stocked by authorised Zodiac spare parts distributors across Europe. Each kit contains two individual lateral units, allowing for targeted replacement of damaged or cracked baskets without necessarily replacing the entire underdrain assembly. The laterals are manufactured from durable, chemically resistant polymer material suited to continuous immersion in chlorinated and salinated pool water environments.

It is important to ensure compatibility by confirming your filter model before ordering. This kit is confirmed for the Zodiac D400 filter. For D520, D640, or D760 series filters, separate lateral part numbers apply (R0597100 and R0597200 series respectively). Fitting incorrect laterals will result in poor sealing and potential sand bypass.

Suitability and installation context

This replacement kit is suitable for pool owners and service technicians maintaining a Zodiac D400 sand filter on a residential swimming pool. Laterals typically require inspection or replacement when sand is observed returning to the pool, when the filter pressure behaves abnormally, or after significant physical disturbance of the filter internals during a sand change. Installing this kit requires partial disassembly of the filter’s underdrain manifold. The quarter-turn design simplifies this process considerably compared to older lateral designs. This is a genuine Zodiac original spare part, ensuring dimensional accuracy and long-term compatibility with the D400 filter system.
