Toilet Leaking At Base

Toilet problems are the bane of every homeowner’s existence. Clogging, leaking, gurgling, refusing to flush… There’s never a convenient time for a toilet to break. Luckily, some fixes are easier than others. This blog post will explore what to do if you notice your toilet leaking at base.

If you’ve noticed water pooling around the base of your toilet, you likely have a leak. Several issues can cause this.

First things first: Stop using the toilet. If the toilet is still in use, the leak will only worsen and cause more damage.

Toilet Leaking at Base? Here’s Why

Broken Wax Seal

A broken seal is one of the most common reasons a toilet leaks from its base. Concealed under the toilet is a wax ring that seals the bottom of the toilet against the top of the sewer pipe and closet flange. Over time, wax toilet seals can harden or loosen and cause water to leak from the toilet’s base.

The fix: Remove the toilet, clean the flange, and replace the wax seal with an improved seal or silicone ring.

Loose Toilet Base

Another potential reason for your toilet leaking from its base is a loose toilet base. The bolts that secure the toilet to the floor can loosen or wear out over time, causing the toilet to rock and allowing water to escape.

The fix: Tighten the bolts that secure the toilet base to the floor. If these are stripped or damaged, you’ll need to replace them.

Damaged Water Supply Hoses

If the toilet leaks from its base when you flush, the water supply hoses may be damaged. These hoses connect the toilet tank to the fill valve and can become cracked or brittle over time, causing water to leak.

The fix: First, try tightening the fittings that secure the hoses to the water line and tank. If this does not solve the leak, you will need to replace the damaged water supply hoses with new ones.

Cracked Toilet Bowl

Sometimes, a toilet can leak from its base if the toilet bowl is cracked. While this is less common, it can happen if the toilet is dropped or otherwise damaged.

The fix: If the toilet bowl is cracked, you will need to replace the entire toilet.

Disconnect Between Toilet Bowl and Tank

If the toilet is leaking from the point where the toilet bowl meets the tank, there may be a disconnect between these two components. If you examine the connection between the tank and bowl, you should find two or three bolts with rubber washers installed inside the tank. When bolts loosen, and washers wear out over time, water may leak from the tank and pool around the toilet base.

The fix: Using an adjustable wrench, tighten the bolt nuts underneath the tank. If the nuts continue spinning, tighten them from inside the tank. If the problem persists, replace the washers to form a water-tight seal.

While toilet leaks can be a pain, they are caused mainly by simple issues you can quickly fix yourself. By troubleshooting the problem and taking care of it right away, you can avoid more severe damage down the road.
