Product Overview

The Pentair TR100/TA100D Sand Filter Lateral 152202Z is a genuine replacement lateral designed for compatible Pentair sand filters. Laterals are located inside the filter tank at the bottom of the sand bed and help collect filtered water while keeping sand media inside the filter.

Compatible with Pentair TR100, TR100C, TR100C-3, TA100, and TA100D sand filter models.

Sold Individually

This listing is for one lateral. Some filter models may require multiple laterals for a complete replacement set.

Benefits

The Pentair 152202Z Sand Filter Lateral helps restore proper filtration by replacing a damaged, cracked, or worn internal lateral. When a lateral fails, sand may escape from the filter and return to the pool, creating cloudy water, sand buildup, or poor filtration performance.

Replacing the damaged lateral helps keep sand media inside the tank and supports proper water flow through the filter. This makes it an important repair part when servicing compatible Pentair TR100, TA100D, Triton, and Tagelus sand filters.

Specifications

Important Compatibility Notes

This lateral is commonly listed for Pentair TR100, TR100C, TR100C-3, TA100, and TA100D filters. For some TR100 applications, this part may apply to specific production years or hub styles. Always confirm your filter model, parts diagram, and hub style before ordering.

Some compatible filters may require multiple laterals for a full replacement set. This item is sold individually, so customers should order the correct quantity for their specific filter.
