About This Item
The Pentair 24900-0002 is the OEM replacement lateral for the Pentair System 3 Sand Filter, Model S7S50. If your filter is channeling water, losing sand to the return lines, or showing uneven backwash, a cracked or broken lateral is the most common cause — this is the correct replacement part.
⚠️ IMPORTANT: 16 LATERALS REQUIRED PER FILTER
The S7S50 lateral assembly requires 16 of this part for a complete set. This listing is for a single lateral (Each). Order the correct quantity before beginning service — a partial set cannot be installed.
The lateral sits within the filter's underdrain hub assembly at the base of the sand bed. It allows filtered water to pass through while retaining sand media inside the tank. A cracked or split lateral allows sand to bypass into the return line and reduces filtration efficiency. Replacing all laterals at the same time — rather than individual broken units — ensures uniform flow distribution across the underdrain and restores full filter performance.

Pro Tip
When sand appears in your pool return lines, inspect all laterals — not just the ones that are visibly cracked. Hairline fractures are common and difficult to spot without removing the lateral from the hub. Since the S7S50 requires 16 laterals and they wear at similar rates, replacing the full set during a single service visit is more cost-effective than returning to the job when a second lateral fails shortly after. Confirm the part number stamped or molded on your existing lateral matches 24900-0002 before ordering.
