Caroma Quietflow 2 M5 Outlet Valve – Universal Dual Flush Cistern Replacement for Caroma, Fowler & Stylus | 750085

Part 750085 is Caroma's genuine outlet valve replacement for the Quietflow 2 M5 platform, built to suit vitreous china (ceramic) cisterns across the Caroma, Fowler, and Stylus ranges dating back to the 1990s. It's a straightforward swap-in for tradespeople handling cistern repairs, restorations, or maintenance callouts — no need to replace the full cistern or suite.

Technical Specifications

Setting Flush Volume

The valve ships adjustable and can be configured on-site to any of the three flush volumes above. Installers have three ways to do this: carry over the setting from the old valve being replaced, look up the toilet suite name against Caroma's Quick Reference Chart, or physically measure the flush and adjust to match.

Suits the Following Suites

Caroma: Viceroy, Vintage, Vand, Sovereign Retro, Sovereign 2000, Sovereign, Regal II, Regal, Profile (Integrated Hand Basin), Profile, Opal II, Opal, Milan, Leda, Harmony, Geo, Elba, Cube, Caravelle 2000, Altisse

Fowler: Seido, Regent, Newport Cube, Newport, Consort

Stylus: Venecia

Superseded Part Numbers

This valve replaces the older 750080 (M5), 413295 (Duoflo Type 2), and 413296 (Duoflo Type 3) outlet valves — a direct upgrade for anyone servicing older square-style mechanisms.

Installation Notes

Cisterns still fitted with the original square-style outlet valve may also need the rear entry inlet valve replaced. Caroma's rear entry inlet valve kit (model 687257) is sold separately and is the recommended companion part for these jobs. Button platform extensions and forward/rear-of-centre button caps are included for dual flush button compatibility.
