Why Is My Toilet Leaking at the Base?
Do you notice water puddled at the base of the toilet? Don’t ignore this problem. Left unaddressed, your toilet will continue leaking slightly with each flush, allowing toilet water to pool on the bathroom floor and potentially causing expensive mold damage and rot in the subfloor.
A toilet spraying out water at the base often signifies a damaged wax ring. This part should make a tight seal between the toilet base and the drainpipe. When it fails, water may seep out every time you flush. Fortunately, it’s not difficult to locate the source of the leak and pinpoint the problem. If you decide the wax ring needs to be replaced, we suggest reaching out to a plumber for qualified toilet repair.
Test Your Leaky Toilet
Sometimes, a nearby leak can make the toilet appear to be leaking at the base. Follow these steps to find out exactly where the water is leaking from.
Check for Condensation
The “leak” around your toilet may not be a leak at all. Rather, water vapor might be condensing on the bowl or tank and puddling onto the floor. To check for this, wipe up any standing water with a towel and flush the toilet. Look closely —if no additional water pools around the base, condensation is the likely problem. Turning on the exhaust fan when you shower is an easy way to solve this problem.
Examine the Toilet Tank
Feel around the exterior of the tank for any wetness. To rule out condensation, wipe up any droplets with a dry washcloth. Then, look again, searching for loose bolts or cracked porcelain leaking water onto the floor. Tighten any loose bolts you notice. If the tank is damaged, you’ll need to replace your toilet.
Inspect the Water Hose
Examine the cold-water supply line on the backside of the toilet. A loose connection, broken hose or malfunctioning shut-off valve sometimes can cause a leak. If tightening the fittings doesn’t resolve the issue, you may need a plumber to replace the water supply hose.
Tighten the Tee Bolts
If these troubleshooting tips don’t solve the problem, your toilet is probably leaking at the base like you suspected. Before reaching out to a plumber, try tightening the tee bolts that secure the toilet to the floor. You may need to take off the decorative plastic caps with a putty knife or flathead screwdriver to access the bolt below. Be careful not to screw the bolt too tight, as this could crack the porcelain. If the bolts spin freely, you could need to buy new ones.
Look for Signs of a Worn-Out Wax Ring
If bolting the toilet tighter to the floor doesn’t stop the leaking, a failing wax ring could be the problem after all. Besides water puddling around the toilet, you may detect a sewage stink, indicating a broken sewer line seal. And if the toilet wobbles, this might mean it’s sitting on a broken flange, the piece of equipment that connects the flush system to the plumbing line. A rocking toilet might also point to a soft subfloor resulting from the leak, which needs immediate attention to prevent the problem from getting worse.
Hire a Plumber to Replace the Wax Ring
If you determine that a faulty wax ring is indeed the problem, repairing it requires removing the toilet, replacing the ring and reinstalling the toilet. While it’s possible to attempt the repair without a plumbing license, DIY toilet removal is not recommended. Here’s why you should leave the issue to a qualified plumber:
- Porcelain is a sometimes brittle material. If you drop the toilet on the floor or hit it too hard with a plumbing tool, it could break, forcing you to pay for a toilet replacement in addition to everything else.
- Lifting and lowering the large plumbing fixture is a two-person task. Even then, poor lifting techniques could leave you with an strained back.
- Checking for water-damaged subflooring requires a experienced eye. And if any damage has occurred, it should be fixed/repaired before reinstalling the toilet, something a plumber can help coordinate.
- If you discover the entire flange at the bottom of the toilet is damaged, it will need to be replaced. This is even more challenging than replacing the wax ring.
- Removing the toilet, making the necessary repair and reinstalling it can take a few hours, if not longer. You most likely have better things to do, giving you yet another reason to leave the job to a plumber.
