Description
The EasyPro SCV20 2" PVC Swing Check Valve is a durable, corrosion-resistant check valve engineered to prevent backflow in pond pump discharge lines, waterfall plumbing, and filtration return systems. The gravity-seated swing flapper opens with minimal resistance when the pump runs — delivering low friction loss for maximum GPH — then drops closed the moment the pump stops, holding the water column in the plumbing line and preventing your biological filter from draining back to the pond.
The SCV20 features 2" slip × slip connections for permanent solvent-weld installation into standard Schedule 40 or 80 PVC. The white PVC body and EPDM rubber flapper seat are corrosion-resistant, UV-stable, and completely fish-safe. Rated for 125–150 PSI working pressure — more than sufficient for any residential pond pump system. Install horizontally or in vertical up-flow orientation only.

Installation Notes
- Identify flow direction before installing — the valve body has a flow arrow. This arrow MUST point in the direction of water flow (from pump outlet toward filter/waterfall).
- Install horizontally whenever possible (the most reliable orientation for swing check valves). Vertical up-flow is acceptable.
- Do NOT install in vertical down-flow orientation — the flapper will hang open under gravity and fail to prevent backflow.
- Clean and dry the pipe ends before applying PVC cement. Apply primer if required by local code or for Schedule 80 joints. Solvent-weld per Christy's Red Hot Blue Glue or equivalent PVC cement instructions.
- Install on the discharge side of the pump (between pump outlet and plumbing line leading to filter or waterfall).
- Install in an accessible location (pump vault, skimmer interior) so the valve can be inspected and the surrounding pipe inspected for debris that might prevent flapper closure.
Frequently Asked Questions
Why is a swing check valve better than a spring check valve for pond pumps?
Swing check valves offer significantly lower friction loss (head pressure) than spring-loaded check valves. A spring check valve must constantly overcome spring tension to stay open while the pump runs — this back-pressure reduces the pump’s effective GPH output. The SCV20’s swing flapper opens fully with the flow and stays open under water pressure alone, adding minimal resistance. This “full-flow” design preserves the pump’s rated GPH and reduces motor stress over time. The only trade-off: swing check valves rely on gravity and backpressure to close, while spring check valves close faster and more positively when flow stops.
What are the connection specs for the EasyPro SCV20?
The SCV20 features 2-inch slip × slip connections — both the inlet and outlet are 2" socket (slip) ends for permanent solvent-weld bonding directly to standard 2" PVC pipe. This connection type is compatible with Schedule 40 and Schedule 80 PVC. No threading, no union connections — the SCV20 is designed for permanent installation using PVC cement.
Important: because this is a permanent installation, plan your installation carefully — if you need to remove the pump seasonally, install a union fitting near the check valve, or consider a union-style check valve instead.
Does this 2-inch PVC valve prevent waterfall drainage when the pump is off?
Yes. When the pump stops, back-pressure from the water column in the plumbing line above pushes the EPDM flapper closed against its seat, sealing the valve. This holds the water in the discharge line and prevents it from draining back to the pond through the pump. Your biological filter stays full of water, the beneficial bacteria colony remains submerged and healthy, and when the pump restarts the waterfall or fountain begins flowing immediately — no wait for the line to refill.
Is the EasyPro SCV20 check valve suitable for horizontal or vertical installation?
The SCV20 is designed primarily for horizontal installation, with vertical up-flow (pump below, valve above, water flowing upward through the valve) also acceptable. The swing flapper uses gravity plus backpressure to seat and seal — this works in horizontal and up-flow orientations. Do not install in vertical down-flow orientation (pump above, water flowing downward through the valve) — in this configuration the flapper would hang open under its own weight, failing to prevent backflow when the pump stops.
What materials is the SCV20 constructed from?
The valve body is rigid white PVC Type I — the same material used for potable water plumbing, highly resistant to corrosion, UV, and pond chemicals. The sealing flapper is EPDM rubber — a durable elastomer that creates a watertight seal against the valve seat and is resistant to ozone, UV, temperature extremes, and most pond chemical environments. Both materials are completely fish-safe and will not leach harmful compounds into pond water.
Can this 2" swing check valve be serviced?
The SCV20 is a sealed unit and is not designed for field disassembly. As a solvent-welded check valve, replacement requires cutting the valve out of the plumbing line and cementing in a new one. To maximize service life: install in an accessible location so you can inspect the valve and surrounding pipe; use a pre-filter or skimmer basket to prevent large debris from reaching the valve; and periodically confirm the flapper is seating properly by listening for water hammer (a single knock when the pump stops indicates proper closure).
