Before You Get Started Gather Up Your Tools & Supplies

Just like with any project you undertake it’s going to take some tools to repair a running toilet in your Northwest Side home. Nothing you’ll need is outside the norm for most homeowners though you may need to go get a hacksaw if that becomes necessary. It might and you’re never going to regret having a hacksaw in your house. But to be clear here’s everything you’re going to need to properly repair a running toilet in your Northwest Side home:

  • Pipe Wrench
  • Pair of Pliers
  • Hacksaw
  • Ruler or Stick
  • Sponge or Towel

Time To Get Started – Testing the Toilet’s Components

Okay, we have all of our tools and supplies ready and time to handle the job properly. Now we just remove the lid from the toilet tank so we can see all of the internal components. Done with that? Alright we’re going to test the toilet flapper first to see if that’s the issue. The toilet flapper is the rubber piece that covers the pipe. It’s connected to the toilet handle by a chain.

Take the stick or ruler you have and push down on the flapper so that it compresses against the pipe opening. Does the running sound stop? If so, then all we have to do is replace the toilet flapper to fix it once and for all. Turn off the water to the toilet and flush it so the tank empties. Remove the flapper and take it to a plumbing supply store to get a replacement.

The Toilet Flapper Wasn’t The Problem So What’s Next?

So we tested the toilet flapper to see if a bad seal may have been the cause of the toilet running with no luck. Next we’ll look at the toilet’s fill valve. This is the pillar usually on the left-hand side of the tank. It’s what the float arm is connected to and where the tube comes from that goes into the overflow pipe. With the tank open flush the toilet and inspect the fill valve in operation. Do you see any water escaping from anywhere other than it should be? Lift the float arm up. Does the water stop coming out of the fill valve? If it stops, you know the fill valve itself is the cause of the toilet running. It’ll have to be replaced.

Replacing a fill valve isn’t difficult just time-consuming. You’ll need to turn off the water and flush the toilet to empty the tank. Now sponge or towel up any remaining water so you can loosen the water supply hose from the bottom of the fill valve. Then just detach the little overflow hose from the nipple on the fill valve and remove it from the tank by pulling it upward.

Take the fill valve you removed with you to the plumbing supply store and get a replacement. Once your home just reattach everything you detached including the water supply and overflow hoses. Adjust the float and make sure the overflow pipe is at least an inch below the critical level mark on the fill valve. This is where the hacksaw comes in handy.
