Waterway 505-1930 Threaded Sand Filter Lateral (Carefree / ClearWater / TWM, Pre-2003 Style)

The Waterway 505-1930 is a replacement threaded-style sand filter lateral used inside select Waterway sand filters, including the Carefree, ClearWater, and TWM series (commonly referenced for pre-2003 style internals). Laterals screw into the internal hub/manifold and are responsible for evenly collecting filtered water while keeping filter sand inside the tank.

What This Part Does

  • Collects filtered water evenly from the sand bed through the slotted lateral “fingers”
  • Helps prevent sand from returning to the pool when laterals are intact and properly installed
  • Supports proper backwash performance by maintaining correct internal flow paths

Key Features

  • Threaded installation (screws into the filter manifold/hub)
  • Replacement lateral for compatible Waterway sand filter internals
  • Ideal for repairs after winter damage, cracks, or broken slots

Specifications

  • Part Number: 505-1930
  • Type: Sand filter lateral (threaded style)
  • Approx. Overall Length: 4-3/8" (measure your existing lateral to confirm)
  • UPC: 806105088642

Compatibility Notes

  • Commonly used in Waterway Carefree, ClearWater, and TWM sand filters.
  • Best practice: match by part number and compare the thread style and length to the lateral you’re replacing.
  • If you are rebuilding the entire internal set, consider replacing the full manifold/lateral assembly to ensure even wear and fit.

Common Signs You Need New Laterals

  • Sand returning to the pool (after verifying correct sand grade and proper valve operation)
  • Cracked lateral body or broken “finger” sections
  • Visible splits at the threaded base or along the slotted area
  • Reduced filtration performance due to internal channeling or bypass from damaged laterals

Maintenance Tips

  • Backwash when filter pressure rises about 8–10 PSI above your clean starting pressure.
  • If you ever open the filter, inspect laterals closely for hairline cracks—small cracks can become sand blow-back problems quickly.
  • Use the correct sand grade and fill level for your filter model; overfilling or incorrect media can stress laterals.
  • When reassembling internals, tighten threaded laterals snugly by hand (do not overtighten and crack the plastic).
