Hayward SPX3100D Threaded Pump Strainer Cover – Super II Series

Part # SPX3100D — replacement threaded strainer cover designed for use with Hayward Super II pump series (models SP3000 and SP3000X). This cover allows access to the pump basket for cleaning while maintaining a secure, leak-free seal.

Key Features

Threaded lid design with integrated port for secure attachment to the pump housing.
Clear or translucent cover (depending on version) — allows visual inspection of strainer basket without disassembly.
Durable plastic construction engineered for pool chemical resistance and outdoor use.
Compatible with Hayward Super II pumps — including models SP3007, SP3010, SP3015, SP3020, SP3025, SP3030 and corresponding SP3000X variants.
Designed to maintain proper O-ring seal and suction, preventing air leaks or loss of prime during operation.

Typical Applications

Used when the original pump strainer cover is cracked, missing, stripped out, leaking air, or when upgrading to a clearer cover for easier maintenance. Suitable for all pools using Super II pumps where regular basket cleaning and inspection is required.

Installation & Compatibility Notes

Before servicing, turn off the pump and relieve pressure. Remove the old cover and O-ring, inspect the sealing surface and clean threads. Install the new SPX3100D cover, ensuring the O-ring seats correctly and threads engage smoothly. Tighten by hand until snug — avoid over-tightening which can cause cracking. After installation, prime the pump and check for leaks or air intrusion.

Why Choose This Cover?

The SPX3100D provides an OEM-quality replacement that restores pump integrity and simplifies maintenance. Its durable construction, clear cover option, and reliable sealing help keep pool pumps operating efficiently and reduce chances of performance issues caused by air leaks or cracked lids.

Maintenance Tips

Inspect the cover and O-ring annually for cracks, wear or compression — replace if seal is compromised.
Keep threads clean and lightly lubricated with a pool-safe silicone lubricant to prevent binding during removal or installation.
When cleaning the pump basket, avoid overtightening the top — hand snug is sufficient to maintain seal.
Store spare O-rings and check them each season to maintain a proper seal and prevent air leaks.
