Oli Inlet Valve for in-wall Cisterns

Is your toilet whistling or filling slowly? If your OLI in-wall cistern makes a high-pitched whistling sound during the refill cycle or takes more than 60 seconds to fill, the internal diaphragm of the inlet valve has failed. The OLI SB0562570 is the official replacement valve designed to restore a quiet, fast refill.

“Does this valve include the vertical adaptor?” Yes. This kit comes complete with the vertical adaptor (the white plastic arm you see immediately after removing the flush plate). You do not need to try and salvage the old, potentially brittle adaptor from your existing setup.

Specifically designed for OLI In-Wall Cisterns (look for the OLI 74 stamp inside the tank).
Suitable for both high and low water pressure systems.
Compact design allows for easy installation through the narrow access hole behind the flush plate.

Q: Does this inlet valve come with the white vertical adaptor?
A: Yes, the SB0562570 includes the vertical adaptor arm as standard. It is a complete “plug and play” unit for OLI in-wall systems.

Q: Can I just replace the washer inside the valve?
A: While possible, the OLI inlet valve body often develops hairline cracks or mineral buildup after 10+ years. Replacing the entire unit ensures a quiet fill and prevents the valve from “sticking” open and wasting water.

Q: Is this compatible with other brands like Geberit?
A: No, this is specifically for OLI cisterns. If your cistern tank says “Geberit,” you will need the Geberit Unifill Inlet Valve.

Are you looking for a Catalano Inlet Valve? If you have a Catalano toilet and need an inlet valve, there is a very high chance you actually need this Oli part.

• The Pairing: While Catalano makes the ceramic bowl, they were historically imported and sold in Australia paired with Oli (Studio Bagno) in-wall cisterns.

• How to Check: Look at your flush plate. If it has a small “Oli” logo or resembles an Oli design, this is the internal valve you require.

• The Fix: This genuine Oli inlet valve is the factory-spec replacement to restore your Catalano suite’s flushing performance.
