Benefits

The Pentair 476001 Gas Valve Replacement Kit helps restore safe and reliable gas control in compatible ETi 400 heaters. If the gas valve is not operating correctly, the heater may fail to ignite, shut down unexpectedly, display service errors, or operate unsafely.

Replacing the failed gas valve with the correct OEM kit helps maintain proper fuel delivery and supports correct heater operation. This can help reduce downtime and avoid replacing the full heater when the gas valve assembly is the only failed component.

For pool professionals, the 476001 kit provides the correct Pentair replacement solution for ETi 400 gas valve service and repair.
