Frequently Asked Questions

What does the Polaris backup valve do?
The backup valve controls the periodic reverse cycle of your Polaris pressure-side pool cleaner. It causes the cleaner to briefly reverse direction at set intervals, preventing it from getting stuck in corners or along walls and ensuring it covers the entire pool floor.

How do I know if my Polaris backup valve needs replacing?
Common signs of a faulty backup valve include the cleaner getting stuck repeatedly in the same spot, failing to reverse direction, or not covering the full pool. If the cleaner moves in circles or stays in one area, the backup valve is often the cause.

Is this a genuine Polaris part?
No — this is a high-quality generic/aftermarket replacement that is compatible with the Polaris 280 and 3900. It replaces genuine Polaris part W7230308 but is not an OEM Polaris product.

Is this backup valve easy to install?
Yes. The backup valve is a direct drop-in replacement and requires no special tools or modifications. It connects to the existing hose fittings on your Polaris cleaner. Refer to your Polaris owner's manual for step-by-step instructions.

Does this suit the Polaris 180 or 380?
This valve is confirmed to suit the Polaris 280 and 3900 only. Compatibility with other Polaris models has not been verified — contact us before ordering if you have a different model.
