As a direct OEM replacement, this check valve meets the exact design intent of the original part, ensuring proper priming function and dependable pump operation.

Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design specification, with the correct seat geometry and seal material required for consistent one-way flow control in a trash pump application.
- Drop-In Replacement — Matches the original mounting interface and port dimensions of the QP4T pump body, allowing straightforward installation without rework or adaptation.
- Broad QP4T Family Fitment — Compatible with QP4TH, QP4TZ, QP4TKT, QP4TB, and QP4TK models, covering Honda, Hatz, Briggs and Stratton, and Kubota engine variants across the lineup.
- Maintains Prime Integrity — A properly functioning check valve prevents backflow in the suction line, allowing the pump to self-prime quickly and hold prime during operation — a worn or failed valve leads to lost prime and reduced pumping capacity.
- Authentic Part Number Traceability — Sold under the verified Multiquip part number 1401350350, eliminating guesswork when ordering and cross-referencing against service documentation.
The check valve in a quick-prime trash pump acts as a one-way gate in the priming or suction circuit, allowing fluid to flow in only one direction while preventing it from flowing back when the pump is not actively moving water. This one-way action is what enables the pump to build suction and self-prime without losing the water column in the line. When the check valve wears, sticks, or fails to seat properly, the pump loses its ability to hold prime, resulting in slow or failed priming, reduced flow, and unnecessary strain on the engine.
