Oli Atlas Close Coupled Outlet Valve

How to check compatibility: The Oli Atlas is designed for “exposed tank” ceramic cisterns rather than in-wall systems.

• The Visual Test: Lift the ceramic lid of your cistern. If your existing valve has the distinct grey/white body and adjustable floats as pictured, this is the correct replacement.

• The Brand Match: This valve is the standard factory fit for the majority of Olympia and Studio Bagno toilet suites.

• Common Symptom: Replace this valve if water is constantly trickling into the toilet bowl or if the buttons no longer trigger a full flush.

Genuine Oli Spare Part — Made in Europe The SB501122 is a high-performance mechanical outlet valve designed for durability. Over time, the internal seals can perish or mineral build-up can prevent the valve from seating correctly, leading to water wastage and phantom flushing.

Key Features:

• Direct Drop-in Replacement: Designed specifically for close-coupled suites.

• Dual Flush Logic: Restores the water-saving 4.5/3L flush functionality.

• Adjustable Height: Allows for fine-tuning to suit different ceramic tank heights.

Please Note: This listing is for the Outlet Valve only. The bottom basket (which stays in the cistern) and the top push buttons are sold separately. If your basket is undamaged, this valve will click straight into your existing housing.

• 8 out of 10 orders delivered on or before time.

• Fast Dispatch: Most orders leave our warehouse within 24 hours.

• Emergency Repair? Order online and select Uber/Courier Pickup from our Mascot location to stop that leak today.

• Q: Does this fit Oli in-wall cisterns?

  • A: No. This is for close-coupled (exposed ceramic tank) toilets only. For in-wall systems, you likely need the Oli 74 or Oli 120 valves

• Q: Will this fix my “ghost flushing”?

  • A: Yes. “Ghost flushing” is usually caused by water slowly leaking out of the valve, triggering the inlet valve to refill the tank. This new assembly will provide a fresh, watertight seal.

Please note: The basket and button are not included with the outlet valve.
