Oli Expert Complete New Style Upgrade & Conversion Kit
The Oli Expert Complete New Style Upgrade Kit is the definitive solution for modernizing an older Oli Expert cistern. This complete set allows you to upgrade discontinued "Old Style" flush valves and buttons to the current, much-improved manufacturer design. By replacing the entire internal suite, you eliminate the common compatibility issues found when trying to mix old metal-button components with new plastic-button mechanisms.
This kit is designed specifically for the older Oli Expert tanks. It is NOT compatible with the New Expert EVO tanks. Please verify your tank model before purchasing.
What's in the Box?
- Complete Dual Flush Plate (Full & Partial Flush)
- New Style Flush Valve (Improved high-performance design)
- Optimized Inlet Valve (Quiet & fast refill)
- Control Block & Air Hoses (Full pneumatic assembly)
Why Upgrade?
As Oli has transitioned from metal to plastic button assemblies, the mechanical "throw" of the flush has changed. This kit provides a 100% compatible internal suite that is more reliable, easier to service, and designed to work in perfect harmony.
Installation Support
Because this kit replaces all the major moving parts within the cistern, it is the most cost-effective way to fix multiple issues (such as slow filling, constant trickling, or sticking buttons) simultaneously.
