The Onga Clacker Assembly (800904K) is a genuine replacement non‑return valve used in Onga LTP and Leisuretime Solar pumps. The clacker sits inside the suction port and acts as a one‑way flapper, allowing water to flow into the pump while preventing it from draining back when the pump switches off.

A worn or damaged clacker can cause the pump to lose prime, take longer to start, or allow air to enter the system — especially in solar installations where maintaining a water column is essential. Replacing the clacker restores proper priming performance and helps protect the pump from running dry.
