How to Fix It – Toilet Leaking

Common Toilet Problems

Is your toilet leaking? Running? Slow filling? Noisy? Or just won’t flush? In this series of blog posts, we will provide you with information about common toilet problems and give you some tips to help you fix your toilet yourself.  In this post, we will discuss the common problems and solutions for when your toilet is leaking. First, let’s learn how a toilet works.

How does a Toilet normally work?

  • Toilet LeakingWhen you push down on the handle, the chain in the tank lifts the stopper
  • Water in the tank flows through the flush valve opening and goes into the toilet bowl
  • The water from the tank forces the waste water in the toilet bowl through the trap and into the main drain area
  • Once the tank is completely empty, the stopper closes and the fill valve refills the tank
  • When the tank is full, the float ball shuts off the fill valve

Now, why is your toilet leaking?

If you find water on the floor, do not flush the toilet. Use towels to soak up the water and dry the area. It is a good idea to leave towels on the floor in case there is any additional leaking.

Loose Connections?

If your toilet is leaking, check all the connections – the tank bolts, the valve mounting nut and the supply tub coupling nut. Make sure each is on tight. If any seem loose, you may need to replace the washers.

How do you fix it? Go to your local hardware store and pick up some new washers. Replace the current washers with the new ones that you just purchased. Insure each is on tight.


If your toilet is leaking, check to see if it is just condensation. The water that enters the tank is usually cooler than the rooms temperature. If your bathroom is not properly ventilated, condensation may drip down the side of the tank onto the floor.

How do you fix it? Open your bathroom window or turn on the fan in your your bathroom. This will help to better ventilate the room and prevent condensation.

Is your tank cracked?

If your toilet is leaking because of a cracked tank, discontinue using the toilet immediately. Drain the water that is currently in the tank and bowl.

How do you fix it? In this case you will need to purchase and install a new toilet tank.
