Installation Instructions

Follow these steps to replace your toilet flapper:

1. Turn off Water Supply: Locate the water supply valve behind or near your toilet and turn it clockwise to shut off the water.
2. Flush Toilet: Flush the toilet to drain the water from the tank. Hold the flush lever down until the tank is empty.
3. Remove Old Flapper: Disconnect the old flapper's chain from the flush lever. Unhook the flapper from the overflow tube's pegs.
4. Install New Flapper: Hook the new Hibbent flapper onto the pegs of the overflow tube. Ensure it is securely seated.
5. Connect Flapper Chain: Attach the stainless steel chain to the flush lever. Adjust the chain length to have minimal slack when the flapper is closed. Too much slack can cause a weak flush, while too little can prevent a proper seal.
6. Turn on Water Supply: Turn the water supply valve counter-clockwise to restore water to the toilet tank.
7. Test Flush: Allow the tank to fill completely, then flush the toilet to ensure the new flapper seals correctly and the toilet flushes efficiently.

Measuring Guide

To ensure you have the correct flapper size, measure your toilet's flush valve:

• Method 1: Measure the middle part of your existing flapper. It must be ≥2.8 inches.
• Method 2: Measure the diameter of the toilet flush valve's opening. This flapper is designed for 3-inch diameter openings.

Troubleshooting

If your toilet is leaking, hissing, constantly running, or experiencing a double flush, it often indicates a worn or improperly seated toilet flapper. Replacing the flapper with a new Hibbent unit can resolve these common issues.

• Continuous Running Water: Check if the flapper is sealing completely. Ensure no debris is preventing it from closing. Adjust the chain to ensure it has minimal slack but is not too tight.
• Weak Flush: The chain might be too long, causing the flapper to close too quickly. Shorten the chain slightly.
• Double Flush: The chain might be too short, causing the flapper to reopen after initial closure. Lengthen the chain slightly.
