Product overview

The Waterway 711-4000 1.5-Inch Union Heater Gasket is a purpose-built replacement seal designed for 1.5-inch heater unions. When a gasket wears or leaks, this part provides a practical, ready-to-use option to restore a reliable connection between heater components.

Why it matters

In spa and pool heating systems, a secure seal at the union joint helps maintain steady performance and minimizes water leakage at the connection point. This gasket is intended to fit standard 1.5-inch unions, supporting a straightforward maintenance workflow and helping to keep equipment operating as intended.

  • Direct replacement for compatible Waterway unions
  • Supports a reliable seal at the union joint
  • Easy to install as part of routine maintenance
  • Suitable for spa and pool heater assemblies

What to expect during installation

Before you begin, power down the system and ensure access to the heater union. Remove the old gasket, clean mating surfaces, and seat the new gasket evenly to avoid pinching. Reassemble and test for leaks following standard safety precautions.

This gasket is designed as a practical, cost-effective replacement option. It works best when used as part of a regular maintenance plan and in combination with compatible components of the system.

  • Inspect for wear and condition prior to replacement
  • Have spare gaskets on hand for timely service
