A small fitting that keeps your water moving efficiently. The Hayward EcoFlo EFC3225SW is a genuine white 90-degree sweep elbow with two identical socket ends — each 2.5 in. inner diameter and 3.5 in. outer diameter — that joins your Hayward equipment union to your pool plumbing. The long-radius sweep curve turns water smoothly rather than with a hard bend, reducing turbulence and head loss so the pump works less to move the same flow. It fits the Hayward EcoFlo union (SPX3200UNKIT) on TriStar, EcoStar, and NorthStar pumps and also serves Universal H-Series heaters, SwimClear filters, and Summit unions.
- Efficient plumbing turn: Makes a smooth 90-degree transition between your Hayward union and pipe with minimal flow restriction.
- Reduces head loss: The sweep (long-radius) design lowers turbulence compared with a standard sharp elbow, which can save pump energy.
- Genuine Hayward part: An exact-fit EcoFlo fitting, not a generic substitute.
- Wide compatibility: Fits the Hayward EcoFlo union on TriStar, EcoStar, and NorthStar pumps, plus Universal H-Series heaters, SwimClear filters, and Summit unions.
- Confirm your equipment uses the Hayward EcoFlo union (union nut, connector, and gasket from the SPX3200UNKIT kit).
- Dry-fit first: one 2.5 in. socket end seats onto the union connector; the other identical socket end takes your pipe.
- Solvent-weld the joints with PVC primer and cement, keeping the elbow oriented so your plumbing routes cleanly.
- Hand-tighten the union nut over its gasket — snug only, do not over-tighten.
- Prime the system, run the pump, and check the connections for leaks.
- This is the sweep elbow fitting only. The union nut, connector, and gasket come in the Hayward SPX3200UNKIT union kit, sold separately.
