Product Overview

The Pentair Rainbow Kreepy Krauly 186 In-Line Leaf Trap | R211084K is a large-capacity debris canister designed for use with suction-side pool cleaners. Installed directly in the cleaner hose line, it captures leaves and larger debris before they can reach the pool pump strainer basket or filtration system.

By trapping debris earlier in the circulation path, the leaf trap helps reduce pump-basket clogging, maintain cleaner suction, and extend the time between equipment cleanings. Its transparent canister makes it easy to monitor debris accumulation, while the snap-open hinged lid and large external handle simplify removal and servicing.

The Model 186 leaf trap provides approximately 5 liters of debris capacity and uses an internal mesh collection bag. Pentair recommends this large-capacity design for pools with heavy leaf loads or debris that would otherwise require frequent pump-basket cleaning. The canister connects to standard suction-cleaner hoses and includes a hose section for installation.

Installation Information

The leaf trap installs in-line between the suction-side cleaner and the pool’s suction connection.

General installation steps:

1. Turn off the pool pump.
2. Remove a section of the existing cleaner hose.
3. Connect the leaf trap into the cleaner hose line.
4. Position the canister in the water according to Pentair instructions.
5. Confirm all hose connections are secure.
6. Remove trapped air from the cleaner hose and canister.
7. Restart the pool pump.
8. Check that the cleaner moves correctly and maintains proper suction.
9. Inspect the canister regularly and empty it before it becomes completely full.

An incorrectly installed or air-filled leaf trap can reduce cleaner performance or allow air to enter the pump system. Make sure the canister remains properly submerged and fully primed.

Cleaning and Maintenance

• Turn off the pool pump before opening the leaf trap.
• Remove the canister from the hose line.
• Release the hinged lid.
• Remove and empty the internal mesh bag.
• Rinse the bag and canister with clean water.
• Inspect the bag for tears or deterioration.
• Check the lid seal and connection fittings for damage.
• Reassemble the unit securely.
• Re-prime the hose and canister before restarting the pump.

Do not allow the bag to become excessively packed with debris, as this can restrict water flow and reduce cleaner performance.
