The Multiquip 1317350350 is a genuine OEM Check Valve designed for Multiquip and STOW trash pump models including QP-201TE, QP-202TH, QP-301TY, QP-301TA, QP-301TH, and T-20H. Sourced directly from Multiquip, this check valve delivers the exact fit and material specification required to keep your pump primed and flowing. Using the correct OEM component ensures the valve seats and seals properly within the pump housing — critical for maintaining prime and preventing backflow. If you are servicing any of the listed QP or T-series trash pumps, verify your unit against the compatible models above before ordering.
Key Features
- OEM Sealing Integrity — Manufactured to Multiquip's exact material and dimensional specification, ensuring the valve seats fully and holds pressure without leaking past the seal face.
- Direct Drop-In Replacement — Engineered to install directly into the pump body on compatible QP and T-series models, using the original mounting configuration with no rework needed.
- Broad Trash Pump Compatibility — Confirmed fitment across QP-201TE, QP-202TH, QP-301TY, QP-301TA, QP-301TH, and T-20H trash pump models.
- Maintains Prime and Flow Direction — A correctly functioning check valve allows fluid to flow in one direction only, keeping the pump primed between cycles and preventing siphon-back when the unit is shut down.
- Genuine OEM Part — Part 1317350350 is an authorized Multiquip component, meaning you receive the same part installed at the factory — not an approximation.
A check valve is a one-way flow control component inside a trash pump that allows fluid to pass through in a single direction while blocking reverse flow. In a trash pump application, the check valve plays a direct role in maintaining prime — without it functioning correctly, the pump loses suction and must be manually reprimed before it will move water or slurry. A worn or failed check valve typically causes the pump to lose prime rapidly after each use, struggle to self-prime, or allow water to drain back through the inlet line when the machine is idle.
