How To Replace Toilet Gasket

Have you noticed water leaking in your toilet? If YES, then all isn’t right. You need to find a solution to avoid toilet falls due to slippery floor, wiping the floor from time to time and unnecessary expenses. Do a thorough inspection to determine the cause. If all indications point to the toilet gasket, then it needs replacement.

A rubber gasket seals the connecting the toilet bowl and the water tank to prevent water leakage. Aging causes cracking of the gasket, and water seeps through the opening. Eventually, it finds its way into the sub-floor, where it can cause damage if the problem isn’t solved. Leaking gasket signs are easily visible and you can’t fail to notice. An oversized gasket, rusted bolts, and poor placement of gasket can also lead to leakage.

However, this usually occurs after gasket replacement or when a repair is being undertaken. Hence, it’s easy to know when an old gasket needs replacement.

Requirements:

  • Washer kit and a new toilet gasket
  • A large driver
  • Moderate size sponge
  • Padding
  • Crest wrench
  • Rags
  • New screws

Step 1: Shutoff the water

The water valve is located on the toilet wall. Shut off the water valve and flush the toilet, ensuring the water in the tank gets finished by holding the handle down. Remove the tank lid and soak the remaining water with a sponge. If the sponge gets too wet, rinse it in the toilet bowl. Repeat the process until no water remains in the tank.

Step 2: Disconnect water supply

Place the rags on the floor since the tank hose pipe usually has some water. Disconnect the water pipe from the tank. You may do this using your hand, but if it’s too tight, use the crest wrench or adjustable pliers. Let the water spin on the rags.

Step 3: Remove tank screws

Sometimes nuts move in the same direction, making it hard to remove the screws. You can prevent these using locking pliers. Take the screwdriver and locate the tank screws. They are found at the bottom if you aren’t aware. Lock one nut with the locking pliers and remove the screw with the screwdriver. Remove the other and place them in a convenient place.

Step 4: Replace the old gasket

Lift the tank from the bowl and turn it upside down. The gasket is not tight. Remove it with your hands ensuring that no rubber material remains. This makes it easy to fit the new gasket as well as prevent leakage. Fit the gasket to the tank knob with the tapered end facing in the opposite direction. Return the tank to the bowl and ensure it sits in the right position. Do this by moving it from right to left until you feel it is alright.

Step 5: Put back the screws

Remember, you are using the new screws and washers. Using old screws can cause leakage as they don’t tighten properly. Put the washers into the screws and put them into the tank holes. Tighten the bolts with your hand until you can’t do it anymore. Now, hold one nut with locking pliers and tighten the screws with the screwdriver. Do the same to the second screw. Tighten them tightly, but not to the extreme.

Step 6: Reconnect the water supply

Now it’s time to reconnect the water supply. Tighten the water supply back to the water tank with your hand. Then, tighten it further with the crest wrench. Turn on the water and allow the tank to fill. Check appropriately if there is any leakage. Flush to make sure it is working as before. If all is good, the job is finished. Wipe the floor and remove all items that are not part of the toilet.

Bottom Line

In conclusion, the replacement of the toilet gasket is a simple DIY exercise. You need not incur extra expenses by calling your plumber who may charge exorbitant fees. Also, the equipment required is easily available at home while the gasket, washers, and screws are purchased at the online store.

You only need to put aside some of your time after work and perform the task. Luckily, the tank is light and you don’t need any help if there is nobody at home. However, you should follow the process carefully for everything to move smoothly and to avoid leakage.
