The Pentair Standard Mesh Bag (R211516) is the OEM replacement mesh bag for the Pentair Leaf Trap series, including Models 179, 179C, and 186 variants. This bag is the debris-collection liner inside the leaf trap canister. When the mesh deteriorates or tears, the trap loses its ability to hold captured debris — leaves, twigs, and other material pass back into the line or clog the housing. Replacing the bag restores full debris retention and keeps the trap functioning as designed.

This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering. Poolaroo Pro Tip Inspect the mesh bag at the start of each season and after any heavy debris event. Small tears along the seam or at the bag collar are the most common failure point — once a tear starts, it spreads quickly under flow pressure. Replacing the bag proactively at the first sign of wear costs far less than clearing a line blocked by a failed bag mid-season.
