Hayward SX310HNRPAK10 Pivot/Ball Sand Filter Lateral Pack, 10-Pack
Genuine Hayward replacement laterals designed to restore the internal collection system in compatible Hayward ProSeries and ProSeries Plus sand filters.
The Hayward SX310HNRPAK10 lateral pack contains ten replacement pivot-style filter laterals for select Hayward ProSeries and ProSeries Plus sand filters. Located at the bottom of the filter tank, the laterals allow filtered water to pass into the internal collection assembly while helping keep filter sand inside the tank. Cracked, damaged, or deteriorated laterals can allow sand to return to the swimming pool and can reduce proper filtration performance.
This 10-pack is an ideal choice when performing a complete internal rebuild or replacing multiple worn laterals at the same time. For an S311SX or S311SXV being updated with the current lower assembly, these laterals are commonly paired with the Hayward SX311MAS lateral holder and bottom elbow assembly.

What Do Sand Filter Laterals Do?
Sand filter laterals are positioned around the lower internal hub of the filter. During normal filtration, water passes through the sand and enters the lateral openings before returning to the pool. The slots in each lateral are designed to allow water through while retaining the filter media inside the tank.
If a lateral cracks or breaks, sand may pass through the damaged opening and appear at the pool returns. A damaged lateral can also interfere with proper filtration and water distribution inside the filter.
When Should I Replace the Laterals?
Replacement should be considered when:
- Filter sand is repeatedly returning to the swimming pool
- A lateral is visibly cracked, split, or damaged
- The filter is being completely rebuilt and the existing laterals show significant wear
- The lower internal assembly is being replaced and you want to renew the complete lateral set at the same time
Because accessing the laterals generally requires removing the filter media, replacing the full set during a major internal repair can help avoid reopening the filter for another damaged lateral later.
S311SX / S311SXV Complete Internal Rebuild
For compatible Hayward S311SX and S311SXV filters requiring a full replacement of the lower internal assembly, the typical current-style combination is:
- SX311MAS - lateral holder assembly, bottom vertical pipe, and bottom elbow assembly
- SX310HNRPAK10 - pack of ten replacement pivot/ball laterals
The SX310HNRPAK10 is the lateral pack only and does not include the SX311MAS center holder or bottom elbow assembly.
Frequently Asked Questions
How many laterals are included with SX310HNRPAK10?
Ten replacement Hayward pivot/ball-style laterals are included.
Does SX310HNRPAK10 include the lateral holder or center pipe?
No. This part number is the 10-pack of laterals only. The lower holder and pipe
assembly are separate components.
Does this work with the Hayward SX311MAS?
Yes. The SX310HNRPAK10 laterals are used with the current-style lower assembly in
compatible S311SX/S311SXV applications.
Can broken filter laterals cause sand to enter my pool?
Yes. A cracked or damaged lateral can allow filter sand to bypass the internal
collection system and travel through the return plumbing into the pool.
Should I replace all ten laterals at once?
If the filter is already emptied and several laterals are aged or damaged, replacing
the complete set is often the most practical approach. Inspect the lateral holder,
center pipe, and lower elbow while the filter is open.
Not Sure If This Is the Correct Hayward Lateral Pack?
Hayward sand filters have used different internal assemblies depending on the model and production year. Aqua Terra Backyard can help identify the correct replacement parts from your filter model number, existing part number, or photos of the internal assembly before you order.
