Valsir Evolut & Tropea 2 Pneumatic Mechanism

Valsir Evolut & Tropea 2 Pneumatic Mechanism: Restore Your Flush Power

Is your concealed toilet cistern losing its “push”? The Valsir Evolut & Tropea 2 Pneumatic Mechanism (Part No. VS0866163) is the engine behind your flush. It converts the air pressure from your push buttons into the mechanical force needed to lift the outlet valve.

Over time, these mechanisms can wear out, leading to unresponsive buttons or a weak flush. As Australia’s exclusive Valsir dealer, we provide the genuine replacement part required to bring your Meco, Hideaway, or Valsir system back to life.

Common Troubleshooting: Is this part your culprit?

• Water in the tubes: If water is leaking back into the blue or white pneumatic tubes, the internal seals are compromised.

• The Valve “Drops” Early: If the flush starts but stops immediately before the tank is empty.

• Unresponsive Buttons: When pushing the plate doesn’t trigger the water release.

Expert DIY Tip: To test your system, remove your push plate and blow directly into the tubes. If the toilet flushes perfectly, your buttons are the problem. If it still fails, you need this Pneumatic Mechanism.

Product Compatibility & Identification

This part is a direct clip-on replacement for several major Australian brands that use Valsir internal components. Check your push plate for the following names:

• Valsir (Evolut & Tropea 2 models)

• Meco

• Hideaway

Please note: This part is not compatible with the newer Winner S or Tropea 3 models.

Specifications & Inclusions

• Full Kit: Includes the mechanism and the required Blue and White pneumatic tubes.

• Easy Installation: Designed to clip directly onto the side of the existing valve.

• Service Recommendation: For the best results, we recommend replacing the outlet valve washer at the same time to ensure a 100% leak-proof seal.
