How To Remove a Toilet Tank Lock Nut?

The first thing you have to do is make sure; that your toilet tank is drained of water. You’ll want to do this; so that when you remove the locknut, no water spills onto the floor or gets on your clothing. It is just better to be safe than sorry. Once that is done, it is time to get cracking on removing the locknut from a toilet tank!

Step 1. Put the Bucket Under the Water Supply Line 

Position the bucket under the water supply line of your toilet tank so that the water drains into it. This will prevent water from spilling out of the tank or onto your floor or carpet.

Step 2: Turn Off the Water Supply Line

It is important to cut off the water supply to the toilet tank. To do it turn the handle on the fill valve, clockwise as long as it stops. 

This prevents you from having to deal with a messy situation that could arise. You may need an adjustable wrench for this step. 

If you have an older toilet, you may want to shut off the water valve under your sink as well. This will stop any running water and prevent it from spraying out of the tank during your removal process.

If you can not find the shut-off valve in your bathroom; then you just shut off the main water supply to eliminate any chance of overflow. You should be able to find this valve in your basement or garage or outside your house near where the water meter is.

Remove the Cover of The Toilet Tank

Grab the toilet tank cover and pull it back to reveal everything inside the toilet tank. If you haven’t cleaned your toilet tank in a while, the lid may be stiffer than usual.

You may need to give it a good wash to get the grime and stains off before putting it back on once you’re finished.

Remove Water From the Tank

To drain the water from your toilet bowl, flush the toilet and wait for all of the water to flow into the bowl. If necessary, repeat this process until you see no more water draining into the bowl.

If all the water cannot be removed from the tank, then try using a sponge, rag, or towel to absorb the remaining water; and then pour the water into an empty bucket for disposal.

Disconnect the Plastic Coupling and Remove it From the Inside of the Tank

First, remove the coupling inside the tank that is connected to an overflow tube inside the tank.

This is easy to do because it’s not connected very tightly.

When you have unscrewed this piece, use the drain stopper to remove any water remaining in your tank.

Remove the Plastic Nut by Unscrewing it

To remove the toilet tank plastic lock nut, all you need is an adjustable wrench or a pair of locking pliers. Hold the lock nut and turn it clockwise as long as it detaches from the toilet tank.

When removing a plastic nut from your toilet tank, be careful: Plastic can break if you apply too much force with the adjustable wrench.

How to Manage a Stuck Lock Nut?

In some cases, a locknut can become stuck. When a lock nut gets stuck, several methods can be used to remove it.

Method 1. Loosen the Screw by Applying Heat; Then Remove it

If your locknut is plastic, you can ease its removal by using a hairdryer to heat it. Hold pliers near the nut while you apply gentle heat with the hairdryer. Once the nut is warm, it should become loose enough to remove with pliers.

Method 2. Use Calcium Dissolver

If the inside of your toilet tank has accumulated calcium deposits, it can be hard to remove the plastic nut, even with a wrench. However, if you have a calcium dissolver, this will remove the calcium and make it easier to remove the plastic nut.

After dissolving the calcium buildup with a chemical, you can proceed with repairing. To determine when the chemical is ready, watch for the formation of a white powder on the surface of the calcium deposits that can be easily wiped away.

What is a Locknut? How do I Fix a Loose One?

 In your toilet tank, the valve controls the water flow. There are two valves in the tank: the fill valve; and the flush valve. These valves get a lot of use and over time they can loosen. The plastic lock nut helps keep them in place; so they don’t come loose or leak. These nuts are located at the bottom of your toilet tank, below the water level. If you notice that your toilet is leaking or running, it may be caused by a loose plastic locknut (or a broken seal). 

To replace your locknut, you must drain the water from both the bowl and tank (if you’re not sure how to do this, please consult with a professional). Then, simply access the plastic locknut using an adjustable wrench. If you are replacing a locknut on a newer model check the instruction manual to see if there are any special instructions or tools required. Once you’ve removed and replaced the old plastic locknut with a new one, turn on the water supply to refill the tank and flush your toilet.
