Replacing a Faulty Fill Valve in Your Toilet

We heard a funny story from one of our Markham plumbers the other day and it made us realize how many people actually have no idea what is going on inside of the bathroom fixture they probably use more than any other. That’s right; we’re talking about the toilet.

Anyway, our Markham plumber was apparently at a friend’s house over the weekend and noticed that the toilet was running. He asked his friend about it and pointed out that a running toilet could add up to hundreds of dollars in wasted water. The friend responded by stating he knew nothing about toilets and planned on getting around to calling Preferred Plumbing to repair it eventually. Our plumber was shocked by this as his brain started spinning through the simplicity of the repair and the amount of money which was being wasted through his friend’s attitude. Needless to say, he immediately dragged his friend to the store, purchased the parts and showed his friend how to repair the toilet in a matter of minutes.

Now, there is never anything wrong with calling a Markham plumber to perform any repairs you don’t feel comfortable with. Actually, we encourage it as it is the way we make our living and because a poorly performed repair can eventually cost significantly more than simply having it repaired by an expert the first time. However, there are some repairs which can be simply performed with anyone with the inclination to try and the ability to read instructions. One such repair is the replacement of the fill valve in the toilet which is one of the most common causes of a running toilet.

Most hardware or plumbing supply stores sell ‘fill valve repair kits’ which come with everything you need for less than $20. Following the instructions, you will see how incredibly simple this repair will be, but we’ll cover the basic outline.

  1. TURN OFF THE WATER SUPPLY TO THE TOILET!! Sorry, for the ‘all-caps’ but this is by far the most important step. If you don’t do this, you’ll end up with a big mess. This can be done by simply turning the valve on the supply line under the toilet.
  2. Remove the tank lid, and flush the toilet to drain the tank, if the tank starts to refill after you flush it, go back to step one and turn off the water before attempting this step again.
  3. Put towels on the floor under the tank, there will be some dripping in the next step from the small amount left in the bottom the tank.
  4. Remove the first plastic nut under the tank and disconnect the supply line where it enters the tank. After that, remove the other plastic nut which secures the fill valve to the tank allowing the valve to be lifted out through the top.
  5. Now, simply reverse these steps according to the instructions in order to install the new fill valve then reconnect the supply line, and turn the water back on and you’re on the way to saving money.

And there you have it; — simple steps and you’ll be saving money in no time. But like we said before, if at any time you feel uncomfortable or like you’re in over your head, please don’t hesitate to call us. Our staff of professional Markham plumbers is always happy to help and willing to explain every step of the work they’re performing.
