The Polaris In-line Back-up Valve (9-100-1200) is a genuine OEM replacement component designed specifically for Polaris 360 pressure-side pool cleaners. This valve plays a critical role in maintaining proper cleaner movement by periodically reversing water flow, allowing the cleaner to pull away from obstacles and continue its cleaning path.

During normal operation, the back-up valve activates at timed intervals to lift and redirect the cleaner. When the valve becomes worn, clogged, or fails internally, the cleaner may become stuck in corners, repeatedly hit steps or walls, or fail to cover the pool evenly. Replacing the back-up valve restores correct cycling behavior and improves overall cleaning efficiency.

Manufactured to Polaris OEM specifications, this in-line valve ensures proper timing, reliable operation, and correct hose integration for Polaris 360 cleaners.


Why the Back-up Valve Matters

The back-up valve is essential for full pool coverage.

Why this matters:

  • Prevents the cleaner from getting stuck

  • Redirects cleaner away from steps and corners

  • Maintains proper cleaning patterns

  • Improves overall pool coverage

  • Reduces unnecessary wear on hoses and fittings

A failing back-up valve often results in poor navigation and missed cleaning areas.


Designed for Polaris 360 Pressure-Side Cleaners

The 9-100-1200 back-up valve is engineered exclusively for use with the Polaris 360 pressure-side pool cleaner. Its internal timing mechanism and flow characteristics are calibrated specifically for this model.

Always confirm cleaner model compatibility before installation, as this valve is not interchangeable with other Polaris models.


Durable Construction for Pool Environments

This back-up valve is constructed from high-quality materials designed to withstand constant water pressure, debris exposure, and outdoor conditions. Its sealed internal mechanism provides consistent cycling while resisting clogging and premature wear.

Using a genuine Polaris back-up valve helps maintain original cleaner performance and navigation behavior.


Installation & Service Notes

For best results:

  • Turn off the pool pump and disconnect the cleaner

  • Locate the existing back-up valve in the cleaner hose line

  • Remove the worn or malfunctioning valve

  • Install the new valve in the correct flow direction

  • Reconnect hoses and test cleaner operation

If the cleaner continues to stall or move erratically, inspect hoses and flow pressure.
