Hayward CX3020FB — Outlet Elbow Replacement

Product Overview

The Hayward CX3020FB outlet elbow is a genuine OEM replacement component designed for use with various Hayward SwimClear™ cartridge filter models. It serves as the outlet fitting that directs filtered water out of the tank and into the return plumbing system when the original elbow is cracked, leaking or worn.

Key Features

• Fits select Hayward SwimClear cartridge filter tanks including models C2020, C2025, C3020, C3025, C4020, C4025, C5020 and C5025.
• Manufactured from durable thermoplastic material designed to withstand pool chemical environments and repeated service cycles.
• Threaded connection for secure sealing into the filter tank outlet port, maintaining proper flow path and minimizing bypass.
• Direct replacement part, enabling service technicians to restore proper plumbing alignment and prevent leaks or flow interruptions.

Technical Specifications

• Part Number: CX3020FB

Installation Instructions

• Turn off pump power and relieve system pressure before servicing the filter tank.
• Drain the filter tank and remove the filter element to access the outlet connection.
• Unscrew and remove the existing outlet elbow; inspect the tank port threads for damage or debris and clean if necessary.
• Apply appropriate thread sealant or PTFE tape to the replacement elbow threads and tighten to manufacturer’s spec (hand-tight plus ¼ turn recommended).
• Reinstall filter element, reassemble the tank, restore pump power, and inspect outlet fitting under pressure for any leaks.

Troubleshooting

• Leak at outlet elbow joint: Ensure thread sealant was applied, threads are not stripped, and the elbow is properly tightened.
• No flow from filter return: Verify that the elbow is correctly installed and that there are no obstructions in the outlet port or plumbing.
• Cracks or damage to elbow body: Replace the part immediately; a compromised outlet elbow can lead to bypass, tank flooding or equipment damage.

Maintenance Tip

At each filter service interval, inspect the outlet elbow for signs of stress, discoloration or cracking—especially after freezing conditions or when filter pressure spikes are observed. Keeping the outlet path in good condition helps maintain proper flow and system efficiency.
