NuFlush

Want a stronger, more reliable flush without replacing your whole system? NuFlush’s 3-inch flappers with adjustable buoys give you control over every flush.

Here’s how it works:
🔧 Position the buoy closer to the flapper for a longer, more powerful flush.
💧 Move it up the chain for a quicker, water-saving flush.

Choose between hard plastic or soft polymer flappers, both work seamlessly with our buoy system. Already have a flapper? You can even add an individual buoy to boost performance instantly!

At NuFlush, we make toilets flush better. Need help picking the right part? Call 1-800-NUFLUSH for free expert support.

✅ More water per flush
✅ Better waste clearance
✅ Fewer double flushes
✅ A toilet that actually works like it should

Compatible with most Kohler models, built to last, and always available with real human support at 1-800-NUFLUSH.
