SEE REPLACEMENT PART: OBSOLETE

The CMP 2" 3-Way Wye [2" S x 2" S x 2" S] is a replacement plumbing wye fitting from Custom Molded Products (CMP) for pool and spa systems that require a three-way branch connection. Wye fittings are used to route or combine water flow through multiple plumbing runs while maintaining a cleaner transition than a sharp directional fitting. This type of component is typically selected during repair, equipment pad plumbing updates, or new installation work where the pipe size and socket configuration must match the planned layout.

Because this fitting becomes part of the glued plumbing system, sizing and orientation should be confirmed before installation. Match part number 21004-000-000, pipe size, and socket type to the existing or planned plumbing design. It is a useful option when replacing a cracked fitting, rebuilding a manifold, or creating a controlled branch point in a pool or spa circulation system.

  • Compatible with properly sized Custom Molded Products (CMP) pool and spa plumbing applications
  • Provides a three-way branch connection for routing or combining water flow
  • Useful for equipment pad repairs, manifold work, and plumbing layout updates
  • Confirm pipe size, socket style, and orientation before cementing into place
  • Use part number 21004-000-000 to help verify the correct replacement fitting
