Geberit Impuls 360 Bottom Entry Inlet Valve

Check your connection size: This valve features a standard 1/2″ (15mm) threaded tail. This is the standard plumbing size for almost all bottom-entry toilet suites in Australia.

How to identify Bottom Entry: If you can see a silver flexible hose connecting a tap on your wall (mini cock) to the underside of your ceramic toilet tank, you have a Bottom Entry cistern. This Geberit 360 is the premium replacement for that setup.

Genuine Geberit 281.000.00.1 (Impuls 360) The Geberit 360 is favored by plumbers across Australia for its reliability and quiet operation. It serves as a universal 15mm replacement for high-end European brands and standard local brands alike.

Compatible Brands & Suites:

• Villeroy & Boch / Duravit / Parisi: The factory-standard replacement for these luxury suites.

• Caroma: A high-performance upgrade for Caroma suites with bottom-entry water connections.

• Universal Application: Because the 15mm (1/2″) connection is the industry standard, this valve fits virtually any ceramic cistern with a bottom-entry hole.

Common Symptoms of Failure:

• High-pitched whistling or vibrating noises during refill.

• Extremely slow tank filling (often caused by a blocked 15mm filter).

• Water trickling into the pan because the valve won’t shut off.

• Q: Is 1/2 inch the same as 15mm?

  • A: Yes. In plumbing terminology, a 1/2″ connection is referred to as 15mm. This valve uses the standard 15mm thread used in Australian homes.

• Q: Does this valve work with high water pressure?

  • A: Yes. The Geberit 360 is rated for high-pressure systems up to 10 bar, though we always recommend a pressure limiting valve if your home exceeds 500kPa.

• Q: Can I replace just the washer?

  • A: While you can replace the Type 360 Diaphragm, if the plastic telescopic body has mineral buildup or is over 10 years old, a full 15mm valve replacement is the more reliable fix.
