How Does a Toilet Tank Bolt work?

How Tight Should Toilet Tank Bolts Be?

You should avoid overtightening your toilet tank bolts because they can crack your toilet bowl or tank. Toilets are made of hard materials (porcelain) that will not flex or bend, so they will break when the toilet tank bolts are overtightened.

They are made of complex but delicate materials, so you need to handle them carefully. Ensure that you use small tools like a small socket or adjustable wrench when tightening the toilet bolts.

Most people believe that the toilet tank bolts should be extremely tight to avoid leaks in the toilet tanks. That is a wrong idea that you must not practice because it can damage your toilet.

Tightening the Toilet Tank Bolts

Toilet tank bolts can be tightened using your fingers, screwdriver, and an adjustable wrench. Tightening your toilet tank bolts is a simple process, and you can complete it within a few minutes. The following tips below will guide you on tightening a toilet tank without breaking the tank or bowl.

Make sure you use Rubber Washers

One of the things that you will need when you want to tighten your toilet tank bolt is rubber washers. Some of the toilet tank bolt kits contain rubber washers. But if the rubber washers are not enough, you may need to buy more either in a physical or online plumbing store.

Since the toilet is made of porcelain, adding a rubber washer between a plastic or metal washer and the porcelain is essential. It would be best to put the rubber washer inside and outside your toilet tank. After putting the rubber washer, you can now put the metal flat washer. The function of the washer is to absorb strain and prevent cracking when tightening the bolts.

Tighten the Nuts onto the Toilet Tank Bolts

After placing both the rubber washer and the metal washer in the right place, you will get the correct nuts and thread them onto all the bolts. Tighten the nuts using your fingers. Depending on the model of your toilet, it may have two or three tank bolts.

If you cannot tighten the nut with your hand, you can use a socket wrench or an adjustable wrench to tighten the nuts. It is advisable to use a small socket or adjustable wrench for this project.

Tighten all Bolts Equally

There are different toilet models, and each of them comes with a different number of toilet tank bolts. Some toilet models have two tank bolts, while others have three. When tightening these bolts, make sure you tighten them equally.

After tightening the first bolt slightly, you move to the remaining ones and tighten them slightly. That is how you continue to tighten each bolt little by little to achieve a wobble-free toilet tank.

This process is time-consuming, but it will prevent you from tightening a bolt than the other. Toilets may crack or leaky seals created if bolts are not tightened equally.

How to Know When You Should Stop Tightening

The first way to know that you should stop tightening is by checking for wobble. If your toilet tank wobbles, you will tighten it a little more. But it would be best if you stopped tightening once you noticed that it does not wobble.

After you have achieved a wobble-free tank, you may check for leaks too. Observe the tank for the next 24 hours; if you notice any leaks, you will carefully tighten the bolts a little more. You don’t need to tighten the bolts a little further if you do not notice any leaking in the next 24 hours.
