Toilet Flange Leak Causes

A toilet flange is an essential component of a toilet unit. Also known as a closet flange, a toilet flange is a pipe fitting that firmly secures a toilet unit to the drainage system on the bathroom floor, ensuring it does not wobble. Aside from attaching the toilet bowl to the floor, this pipe fitting connects the toilet unit to the drainpipe that carries wastewater away from your home.

This pipe fitting is bolted to the bathroom floor and sealed tightly to the waste pipe by a rubber gasket and a wax ring. A toilet flange that’s in good working condition prevents water and gas leaks. However, a toilet flange can leak due to many reasons.

Let’s look at some of the reasons why a toilet flange can leak.

  • Loose mounting bolts

A toilet flange is attached to the floor with mounting bolts. These bolts can loosen over time and break the watertight seal between the flange and the bathroom floor, thereby causing leaks. Loose bolts can not only cause toilet leaks, but they can also cause your toilet to wobble, rendering it unusable. While tightening the bolts can solve the problem in some cases, it may be advisable to replace the bolts together with the rubber gasket and wax ring to ensure the problem is solved effectively.

  • Old wax ring

A wax ring is installed between the toilet flange and the base of your toilet to create a watertight seal that prevents flush water from leaking. Like other parts of your toilet, the wax ring can wear out over time and lose its seal. A toilet wax ring cannot be repaired. If the wax ring is worn out, you will need to call an experienced plumber to replace it.

  • Cracked toilet flange

A toilet flange can crack or break when your toilet wobbles continuously or due to overtightened bolts. Also, it can deteriorate over time and lose its watertight and airtight seal. The only solution to a cracked toilet flange is to replace it.

  • Toilet Flange Is Too Long or Too Short

A toilet flange should be the right height to work properly. If it’s too short, it will leave a gap where flush water will escape. On the other hand, a toilet flange that’s too long may cause your toilet to wobble and eventually cause leaking.

Signs of A Leaking Toilet Flange

  • Water around the base of your toilet
  • Sewer odors in your bathroom
  • Water stains on the ceiling below an upstairs bathroom
  • Toilet bowl moves back and forth
