Hayward SPX5500A Pump Housing (Power-Flo Matrix / SP1590 Series)
Hayward SPX5500A is a genuine replacement pump housing for the Hayward Power-Flo Matrix pump series. This is the main wet-end housing/body that the strainer and internal pump components mount to. Replace it when the original housing is cracked, leaking, stripped at the ports, or damaged from freeze or impact.
Key Features
- Part Number: SPX5500A
- Brand: Hayward
- Type: Pump housing (wet-end body)
- Pool Type: In-ground (open line part listing)
- Designed for reliable fit and sealing on compatible Hayward Matrix wet ends
Common Compatibility
- Hayward Power-Flo Matrix pump series: SP1591, SP1592, SP1592FT, SP1593
Common Reasons to Replace
- Housing crack or leak (often from freezing or overtightened fittings)
- Stripped threads at the ports or damaged union/fitting interface
- Persistent seepage that isn’t resolved with new O-rings/gaskets
- Warped sealing surfaces that prevent proper wet-end sealing
Installation Notes
- Match the pump model (SP1590 family) and compare housing style/port layout before ordering.
- Shut off power and drain the pump before disassembly.
- Inspect and replace sealing parts (shaft seal and housing O-rings) during a housing swap.
- Use thread sealant appropriate for pool plastics on threaded fittings and avoid overtightening.
- Prime the pump after reassembly and inspect closely for leaks during startup.

Maintenance Tips
- Keep lid and housing seals clean and lightly lubricated to reduce air leaks and prime loss.
- Winterize properly—freeze damage is a common cause of cracked pump housings.
- Avoid overtightening threaded fittings; use the correct sealant and hand-tighten plus a small turn if needed.
- If you see recurring leaks, inspect the housing sealing surfaces for warping or hairline cracks.
