A leaking toilet is a common plumbing problem that can waste water and increase your water bills. Fortunately, fixing a leaking toilet is usually a relatively simple task that you can do yourself with the right tools and materials. In this comprehensive guide, we’ll provide you with step-by-step instructions on how to fix a leaking toilet, covering all the common causes and solutions.
Identifying the Source of the Leak
Before you start fixing the leak, it’s important to identify the source. Here are some common indicators of where the leak might be coming from:
- Base of the toilet: Water pooling around the base of the toilet may indicate a leak from the base seal or a loose toilet flange.
- Tank: A leak from the tank will typically cause water to drip into the bowl when the toilet is not in use.
- Fill valve: The fill valve controls the water level in the tank. A faulty fill valve can cause the tank to overfill, leading to a leak.
- Flush valve: The flush valve opens and closes to flush the toilet. A worn-out flush valve can cause water to leak into the bowl after flushing.
Tools and Materials You’ll Need
- Adjustable wrench
- Plumber’s putty
- Toilet bowl wax ring
- New toilet flapper
- New fill valve
- New flush valve
- Rags or towels
Step-by-Step Instructions
1. Turn Off the Water Supply
Start by turning off the water supply to the toilet. The shut-off valve is usually located behind the toilet or on the wall near the base.
2. Flush the Toilet and Unbolt the Toilet
Flush the toilet to empty the tank and bowl. Unbolt the toilet from the floor by removing the nuts holding it in place.
3. Remove the Old Wax Ring
Use a knife or putty knife to remove the old wax ring from the base of the toilet and the flange on the floor.
4. Install the New Wax Ring
Place the new wax ring on the flange, making sure it is centered and the ring is facing the correct direction.
5. Set the Toilet on the Wax Ring
Carefully lift the toilet and set it back on the wax ring. Make sure the toilet is aligned properly and the base is flush with the floor.
6. Tighten the Bolts
Tighten the nuts holding the toilet to the floor, alternating between them to ensure even tightening. Do not overtighten.
7. Reconnect the Water Supply
Turn on the water supply and check for leaks. Tighten the nuts further if necessary.
