A leaking toilet base is more than just a plumbing nuisance; it can also cause serious damage to your bathroom. If you’ve noticed water pooling around your toilet, it’s important to take action immediately. Before you contact a plumber, it’s helpful to understand the root cause of the problem.
Here are five of the most common reasons toilet bases leak.
The Wax Ring Is Damaged or Has Come Loose
The wax ring is a donut-shaped wax that forms a seal between the bottom of the toilet and the drainpipe. Over time, the wax ring can become damaged or dislodged, allowing water to leak from under the toilet. If you suspect the wax ring is the problem, it’s best to call a plumber so they can replace it for you.
The Bolts That Secure the Toilet to the Floor Are Loose or Have Come Undone
If your toilet is leaking from around the base, it could be because the bolts that hold it in place have come loose or have fallen out. This is an easy problem to fix yourself; simply tighten the bolts until they’re snug. You may need to replace them entirely if they’re too far gone. If you’re uncomfortable doing this yourself, it’s best to call a professional plumber.
There’s a Crack in the Porcelain Around the Base of the Toilet
Although porcelain toilets are built to last, they can develop cracks over time — especially if they’re dropped or knocked over (which happens more often than you might think). If there’s a crack in your toilet, water will seep through and cause leaks. The only way to fix this problem is to replace the toilet altogether.
The Flange Is Corroded or Damaged
The flange is the pipe fitting that connects the toilet to the drain. If it’s corroded or damaged, it can cause water to leak out from around the base of the toilet. If you think this might be the problem, you’ll need to replace the flange.
The Caulk or Grout Around the Toilet’s Base Is Cracked or Missing
Caulk and grout seal gaps and cracks around toilets (and other fixtures). Over time, this can crack or deteriorate, allowing water to seep through. If you think this might be the problem, remove the old caulk or grout and apply a new layer around the base of the toilet.
