📜 Product Background:

The SX311CD1FWS Top Elbow Assembly was introduced as part of Hayward's effort to improve hydraulic efficiency in its ProSeries Plus sand filter line, notably the S311 model. This elbow connects the top of the internal lateral and diffuser system to the external multiport valve, directing flow during the filtration and cleaning cycles. Over time, elbow assemblies can crack due to pressure surges or UV degradation, leading to reduced flow rates or leaks. Replacing it with the original OEM part ensures your system continues running smoothly.

🛠️ Installation Tips & Tricks:

1. Turn Off the Pump: Disconnect power at the circuit breaker to ensure safety.

2. Relieve Tank Pressure: Open the air relief valve and/or remove the drain plug at the base of the filter.

3. Remove Multiport Valve: Unscrew or unbolt the valve to access the top diffuser and elbow assembly.

4. Disconnect Old Elbow: Gently remove the existing elbow from the diffuser pipe, taking care not to damage lateral connections.

5. Inspect the O-Rings: Clean and lubricate or replace any O-rings to ensure a watertight seal.

6. Install New Elbow Assembly: Press the new SX311CD1FWS elbow into place and reconnect to the multiport valve.

7. Reassemble System: Secure all connections, prime the pump, and check for leaks before resuming normal operation.
