How Do You Unstick A Float Valve?

Float valves are vital components of many plumbing systems, particularly those that rely on tanks for water storage. They are responsible for regulating the flow of water into and out of the tank, ensuring that the water level remains constant. However, sometimes float valves can get stuck, preventing them from functioning properly. In this article, we will discuss how to unstick a float valve so that your plumbing system can continue to function as it should.

Step 1: Turn Off the Water Supply

The first step in un-sticking a float valve is to turn off the water supply. This will ensure that no more water flows into the tank while you are working on the valve. It is important to turn off the water supply before attempting to unstick the valve, as water can create a short circuit or cause other damage to your plumbing system if it comes into contact with electrical components.

Step 2: Remove the Float Valve Cover

The next step is to remove the float valve cover. This cover is usually located on the top of the tank and can be removed by unscrewing it or simply lifting it off. Once you have removed the cover, you should be able to see the float valve and its components.

Step 3: Inspect the Valve Components

Before attempting to unstick the valve, it is important to inspect its components. Look for any signs of damage or wear and tear, such as cracks, corrosion, or buildup of sediment. If you notice any damage, you may need to replace the valve or its components.

Step 4: Clean the Valve Components

If the valve components are not damaged, the next step is to clean them. Use a soft-bristled brush or cloth to remove any dirt, debris, or sediment that may be preventing the valve from moving freely. Be sure to clean both the valve body and the float arm thoroughly.

Step 5: Apply Lubricant

After cleaning the valve components, apply a small amount of lubricant to the valve body and float arm. This will help to reduce friction and allow the valve to move more freely. Be sure to use a lubricant that is safe for use with plumbing systems, such as silicone grease or plumber’s grease.

Step 6: Test the Valve

Once you have cleaned and lubricated the valve, it is time to test it. Turn the water supply back on and observe the valve as water enters the tank. The valve should move freely and smoothly as the water level rises. If the valve still appears to be stuck, repeat the cleaning and lubrication process or consider replacing the valve.

Conclusion

Float valves are essential components of many plumbing systems, and it is important to keep them functioning properly. If your float valve becomes stuck, follow these steps to unstick it and restore your plumbing system to its normal operation. Remember to always turn off the water supply and take safety precautions when working with plumbing components.
