Pentair Cristal-Flo T-300BP-2 side strainer – 21180-0100

The Pentair 21180-0100 lateral is a replacement part for the Sta-Rite Cristal-Flo T-300BP-2 sand filter. Also called a “lateral,” it is part of the collection network located at the bottom of the tank.

Keep the media inside the filter

The laterals allow filtered water to reach the collector while retaining the media in the tank. A cracked or damaged lateral can allow sand to pass into the water returns. Replacing it may repair the internal network without replacing the entire filter when the other components are in good condition.

Compatibility must be confirmed with the exact part number

Part number 21180-0100 is listed for the Cristal-Flo T-300BP-2 in the T-BP series. The Cristal-Flo name alone is not enough to choose the part: compare the filter’s complete model, its exploded view, and the installed lateral. Different versions may use different internal components.

Part specifications

Brand: Pentair / Sta-Rite. Part number: 21180-0100. Type: sand filter lateral. Indicated filter model: Cristal-Flo T-300BP-2. This listing is for a replacement lateral, not the central collector or a complete filter.

Take the opportunity to inspect the entire assembly

When working on the media, check all the laterals, their connections, and the collector. Sand in the pool can have several causes; an inspection helps identify the parts that are actually damaged before reassembly.
