Valterra 200-CU20 PVC Swing/Spring Check Valve, 2ft Union - Clear

In this review the Valterra 200-CU20 is examined as a practical, low-cost check valve for irrigation, pool, and light industrial uses. The clear schedule 40 PVC body gives immediate visual confirmation of operation and makes troubleshooting faster, while the swing/spring design and EPDM seal provide reliable one-way flow in most landscape and aquaculture systems. The bottom line: it is best for users who need simple, visible check action and easy installation at moderate pressure up to 150 psi.

Key Features

• Clear schedule 40 PVC body: lets installers visually confirm flow and valve movement without disassembly, speeding diagnosis of blockages or reverse flow.
• EPDM seal: resists water and oils so the valve maintains a tight seal in irrigation and pool environments where moisture exposure is constant.
• Swing/spring combination: allows installation in any orientation while the 1/2 lb spring tension helps the valve close quickly to reduce backflow.
• 2' slip union connections: provide a solvent-weld joint for a leak-resistant installation when glued into PVC piping runs.
• 150 psi maximum pressure rating: makes the valve suitable for most residential and light commercial irrigation and pond systems.

Who It's For

The Valterra 200-CU20 is aimed at landscapers, irrigation hobbyists, and pool or pond owners who need a straightforward check valve they can watch in action. Its clear body and simple spring assist make it useful where visual confirmation of operation is valuable, such as troubleshooting drip or sprinkler circuits and small aquaculture plumbing.

Those needing heavy industrial durability or valves rated for aggressive chemicals should look elsewhere; while the PVC and EPDM materials resist corrosion and mild chemicals, long-term wear in harsh environments has mixed user feedback and some report limited lifespan under heavy use.

Pros & Cons

Pros

• Easy to install with standard 2' slip connections for solvent welding into PVC lines.
• Clear body gives excellent visibility of valve action for quick diagnostics.
• EPDM seal and 1/2 lb spring tension provide effective one-way flow control with minimal reverse leakage in most cases.
• Lightweight schedule 40 PVC construction resists corrosion and mild chemicals.

Cons

• Some customers report mixed long-term durability, so it may not be ideal for very heavy-duty continuous duty installations.
• Requires proper glue joints on the slip unions; incorrect installation can cause leaks.

Specifications

Our Verdict

The Valterra 200-CU20 is a practical, cost-effective check valve for residential and light commercial irrigation, pool, and aquaculture plumbing where visual confirmation and easy installation matter. It offers solid functionality and minimal reverse leakage for most typical systems, but buyers expecting industrial-grade longevity should consider more heavy-duty materials.

Frequently Asked Questions

Can this valve be installed in any orientation?
Yes. The swing/spring combination construction allows installation in any position.

What pipe joining method is required?
Each end is a 2' slip connection designed to be fastened with PVC solvent cement.

Is the valve suitable for pool water and irrigation?
Yes. The EPDM seal resists water and oils and the PVC body resists corrosion and mild chemicals, making it suitable for those applications.
