Waterway 711-4010 – 2″ Flat Union Gasket
Product Overview
The Waterway 711-4010 is a replacement flat gasket designed for 2″ union connections commonly used in pool filtration and pump systems. It helps create a reliable, leak-resistant seal in static plumbing unions.
Key Features
- Flat gasket designed for 2″ union fittings.
- High-quality material suitable for pool and spa plumbing environments.
- Simple and cost-effective service part for maintaining proper system sealing.
- Compact and easy to install during routine maintenance.
Technical Specifications
- Part Number: 711-4010
- Inside Diameter: approximately 2-1/8″
- Outside Diameter: approximately 2-15/16″
- Material: durable gasket material (flat style)
- Application: 2″ union connection in pool/spa plumbing
Applications & Fitment
This gasket is used in plumbing unions that require a flat sealing surface and match the dimension of the 2″ union size. It’s ideal for servicing leaks or replacing worn seals where the original union gasket has become damaged or deformed.
Installation Instructions
- Turn off pump and relieve all pressure from the plumbing before servicing.
- Disassemble the union connection, remove the old gasket and clean the sealing surfaces of any debris or buildup.
- Place the new 711-4010 gasket into the union face, ensuring it is seated flat and properly aligned.
- Re-assemble the union, tighten according to manufacturer recommendations, and restore flow. Check for leaks at the connection during startup.
Troubleshooting
- Leak at just serviced union: Verify the gasket is seated flat, the sealing faces are clean and parallel, and the union hardware is snug but not overtightened.
- Gasket appearing deformed or pushed out: Check that the union faces are clean and true; replace if the union housing is damaged.
- Repeated leaks after seal installation: Inspect the union body and threads for damage or misalignment, and ensure correct orientation of the gasket.
Maintenance Tip
As part of your annual service routine, inspect all union gaskets for flattening, cracking or chemical wear. Replacing the 711-4010 gasket when signs of degradation appear prevents leaks, protects pump systems, and maintains system efficiency.
