How to Fix a Leaky Toilet

By Mrs. Fixit

You may not be able to actually fix a toilet yourself, but with the help of this tip from Mrs. Fixit you'll know what's wrong before you call a plumber. And knowing the problem will likely save you money on unnecessary repairs.

Things You?ll Need to Fix a Leaky Toilet:

Food Coloring


It?s easy enough to tell that the toilet is leaking; unfortunately, it isn?t as easy to tell where it?s leaking from. Here are some easy ways to figure out exactly what needs to be fixed!

  1. Take the top off the tank and put a few drops of food coloring in the water. Leave a note on the toilet that no one should use it and wait an hour or two.
  2. Check to see where the food coloring is. If it found its way into the bowl, your flapper valve is leaking and probably needs to be replaced. Before you replace it, try lifting up the flapper and scrubbing the inside seat. There may just be some mineral deposits preventing you from getting a tight seal.
  3. If the colored water is dripping out the back of the toilet by the pipes, you need to replace the seal between the tank and the bowl.
  4. Flush the toilet. If the water pools up at the base of the toilet, the wax ring is cracked and needs to be replaced.
