Stop the Drip: A Quick Guide to Fixing a Leaky Toilet Flapper  

Is your toilet’s persistent dripping driving you up the wall (not to mention the water bill)? Don’t let a small leak become a big headache. Fixing a leaky toilet flapper is a simple DIY job that can save you money and hassle. This quick guide will have you back in business in no time.

What You’ll Need:

  • Replacement flapper (matching your toilet model) – see recommendation below
  • Adjustable wrench
  • Pliers (optional)

Steps to Success:

  1. Turn Off the Water: Locate the water supply valve behind the toilet and turn it off clockwise. Flush the toilet to empty the tank.
  2. Remove the Old Flapper: Unscrew the flapper chain from the flush arm, then detach the flapper from the overflow tube by twisting the plastic nuts. Inspect the old flapper for cracks, tears, or mineral buildup – these could be the culprits behind the leak.
  3. Install the New Flapper: Place the new flapper on the overflow tube, aligning the holes with the plastic nuts. Screw the nuts back on snugly. Reattach the chain to the flush arm with a slight slack.
  4. Turn On the Water and Test: Slowly turn the water supply valve back on. Listen for any leaks and check the flapper for proper sealing. Give the flush handle a few test presses to ensure everything is working smoothly.
