Hayward SX180K Pro-Series Sand Filter Base (with Screws & Washers)
The Hayward SX180K is a genuine OEM replacement filter base — designed to support and stabilize Hayward Pro-Series sand filters. It serves as the foundational platform onto which the filter tank, internal laterals, and plumbing components mount. If the original base is cracked, damaged, or degraded, replacing it with SX180K restores structural integrity and safe operation of the filtration system.

When to Replace
Replace the base when the existing unit shows structural damage — such as cracks, stress fractures, or warping — or if bolts/washers are missing or corroded. A compromised base can lead to misalignment, uneven tank stress, leaks, or premature failure of the filter system.
Installation & Maintenance Tips
- Ensure the filter tank and internal laterals are removed before replacing the base to avoid stress or misalignment during installation.
- Use the included screws and washers to securely fasten the base per manufacturer torque specs, ensuring level installation on a stable equipment pad.
- After installation, verify proper seating and alignment of the filter body and all plumbing connections before refilling the system with sand and water.
- Inspect periodically for base integrity, especially in older filters or after heavy usage seasons; replacing the base can help avoid catastrophic filter failures down the line.
Why Choose SX180K
If you own a Hayward Pro-Series sand filter and the original base is damaged or missing, the SX180K is the correct OEM replacement. It restores structural stability, ensures safe, proper operation, and helps extend the usable life of your filter — often eliminating the need to replace the entire filtration system.
