A leaking toilet can be a nuisance and a significant waste of water. Often, the source of the leak stems from a faulty gasket between the toilet tank and the bowl. Fortunately, this is a repair that you can handle yourself, saving both water and money. In this tutorial, we will provide a comprehensive guide on how to install a universal toilet tank gasket step-by-step. Follow along to ensure your toilet functions properly.
What You Will Need
Before starting, ensure you have the following tools and materials:
- Universal toilet tank gasket kit
- Adjustable wrench
- Flathead screwdriver
- Plumber’s putty or silicone (optional)
- Bucket or towels
- Gloves (optional)
Step 1: Preparation
The first step involves preparing your workspace:
- Turn off the water supply to the toilet. The shut-off valve is usually located behind the toilet.
- Flush the toilet to empty the tank, then use a sponge or towel to absorb any remaining water in the tank.
- Place a bucket underneath the tank’s outlet to catch any residual water that may leak during the process.
Step 2: Remove the Toilet Tank
Next, you’ll want to detach the toilet tank from the bowl:
- Use a flathead screwdriver to loosen the nuts securing the tank to the bowl from beneath. Use the adjustable wrench if the nuts are too tight.
- Carefully lift the tank off the bowl. Be mindful, as it can be heavy and waterlogged.
- Set the tank on a stable, flat surface, such as a workbench or a layer of towels to prevent scratches.
Step 3: Remove the Old Gasket
With the tank removed, it’s time to take out the old gasket:
- Locate the old gasket sealing the tank. It will be positioned where the tank touches the bowl.
- Carefully peel the old gasket away from the tank and the bowl. If it sticks, use a flathead screwdriver to gently pry it loose.
- Inspect the sealing surface of both the tank and the bowl for any debris or leftover bits of the gasket. Clean these surfaces with a damp cloth.
Step 4: Install the New Gasket
Installing the new gasket is critical to preventing leaks:
- Take your new universal gasket and place it on the tank’s outlet (the opening where the tank connects to the bowl).
- Align the holes on the gasket with the mounting holes in the tank.
- Press it firmly into place to ensure a snug fit. If needed, add some plumber’s putty or silicone around the edges for an extra seal.
Step 5: Reattach the Toilet Tank
With the new gasket securely in place, it’s time to reattach the tank:
- Position the tank back onto the bowl, ensuring the gasket remains aligned.
- From beneath the bowl, hand-tighten the nuts onto the tank bolts, then use the wrench for a snug fit—do not overtighten as this may crack the porcelain.
Step 6: Reconnect the Water Supply
Now that the tank is in place, you can reconnect the water supply:
- Open the shut-off valve to allow water to flow to the tank.
- Check for leaks around the gasket and the connections. If there’s any water leakage, tighten the nuts slightly as needed.
- Flush the toilet and observe if everything is functioning correctly.
Step 7: Clean Up
Once everything is properly secured and functioning:
- Clear away any tools and materials used during the installation.
- Dispose of the old gasket and any debris responsibly.
- Wipe down the areas around the toilet tank and bowl to maintain cleanliness.
