Old Style Multikwik Multiflush Toilet Flush Valve Seal | Replacement Diaphragm
Features
Stop your toilet from leaking with this light grey replacement seal for the “Old Style” Multikwik Multiflush valve. As the original valve is no longer in production, these replacement washers are essential for maintaining your existing system. Over time, original seals can shrink, distort, or blister, leading to a constant, wasteful drip into your toilet pan. This replacement diaphragm is a simple, budget-friendly solution that helps you save water and avoid the need for a full toilet plumbing overhaul.
- Dedicated Design: Specifically engineered to fit the discontinued “Old Style” Multikwik Multiflush valve.
- Fixes Common Leaks: Replaces damaged or bubbled seals that cause continuous, annoying water trickles.
- Precision Fit: Features an external diameter of 60mm and an internal diameter of 27mm.
- Easy Installation: Designed for a straightforward swap—simply quarter-turn the valve body to access the washer.
- Secure Your Spares: Since the original valve is no longer manufactured, these essential seals are becoming increasingly difficult to find.

Details
A leaking toilet is frustrating, silent, and expensive. When the flush valve washer fails, water continuously bypasses the seal, trickling into the pan 24/7. Many homeowners worry this requires an expensive plumber or a complete toilet replacement, especially for older or discontinued systems.
The reality is that this seal is usually the only part at fault. You can fix this yourself in minutes. Turn off the water, perform a quick quarter-turn to release the valve body, swap the old washer for this new one, and reinstall. It is a cost-effective way to restore your toilet’s efficiency and stop the water waste immediately.
