Restore Full Cleaning Power with the Polaris G52 Back Up Valve

If your Polaris pressure-side pool cleaner gets stuck in corners, it may have a problem. It might also spin in place or miss large areas. The issue could be with your back-up valve. The Polaris G52 Back Up Valve is the official replacement part. It helps your cleaner move freely. This ensures your pool gets full and efficient coverage every time.

This important part works quietly to redirect water flow. It helps your cleaner move past obstacles and reach all areas of your pool, including deep ends and tight steps. If the valve is worn out or not working, replacing it is a quick and effective way to improve your cleaner's performance.


Why the Back Up Valve is Critical to Pool Cleaning

The back-up valve is more than just another part in your Polaris cleaner — it’s the key to keeping your system moving freely. Here’s what it does:

  • Helps the cleaner get out of tight spots – The valve changes the water flow every 3 to 5 minutes. This helps the cleaner move to a better position.

  • Prevents missed spots – Ensures no area of the pool is left untouched.

  • Reduces wear and tear – Stops the cleaner from spinning in place and straining internal gears.

  • Saves time – Eliminates manual intervention with brushes or nets.

Without a functioning G52, your cleaner’s efficiency can drop by as much as 50%. That means more debris left behind, more work for your filter, and more time spent cleaning your pool manually.


OEM Quality You Can Trust

When it comes to Polaris pool parts, OEM quality matters. The G52 is engineered to Polaris’ strict specifications, ensuring:

  • Exact fit – Twist-lock design connects securely with no leaks.

  • Durable housing – UV and chemical-resistant materials for long life.

  • Precision mechanics – Integrated timer valve ensures consistent cycles.

  • Proven reliability – The same component trusted by pool pros worldwide.

Expert Tip: Cheap aftermarket back-up valves often fail within a season, costing you more in the long run. We’ve seen it first-hand in our service department — stick with OEM for guaranteed results.

Signs Your G52 Valve Needs Replacement

A worn or damaged back-up valve can cause:

  • Cleaner spinning in circles

  • Cleaner stuck against walls or steps

  • Short or no back-up cycle

  • Visible cracks or leaks in housing

  • Reduced cleaner coverage

  • Excessive strain on the feed hose

If you notice any of these symptoms, replacing the valve can make an immediate difference in your cleaner’s performance.


Quick DIY Installation

Replacing your Polaris G52 is straightforward and requires no special tools:

  1. Turn off your pool pump.

  2. Disconnect the old G52 valve from the feed hose.

  3. Snap in the new valve in the same location.

Within minutes, your cleaner should lift and reposition itself at regular intervals, covering your pool completely.
