In this method, we will explain an easy way to stop the overflow of water in your bathtub. For this reason, you will need to check some aspects of the bathtub before you decide to repair it. The bathtub’s overflow system is connected to the central plumbing line, so you have to check the central plumbing line’s water leakage. This will provide you an idea about the extent of overflow that the bathtub is causing. Assessing this situation, you can quickly start working.

Now you have to open the overflow knob of the bathtub for this purpose you will only require a screwdriver, not much tools are necessary for this task; but before you start working you should be much careful about the personal safety, the floor of the bathtub should be adequately dried, and there should adequate adhesives so that you do not skid inside the bathtub.

Now you have to take a screwdriver and then open the bathtub’s overflow knob; usually, the overflow knob is situated at the top of the bathtub. The screwdriver will be enough to open the knob. Once you have opened the knob, you can observe a retainer flip and a gasket holding the exit pipe. The retainer flip and the gasket should be checked properly because the overflow is positively related to these two instruments’ condition.

Sometimes the overflow in bathtub occurs due to the displacement of the retainer flip and the gasket. So you must repair these two elements. The retainer flip should attach the ceramic of the bathtub and the plumbing pipe. This will act as a bridge to the connection between these two parts. But the retainer flips gest inward due to frequent use. In such cases, the water gets overflowed. So you have to take the gasket, and the retainer flips out of the bathtub.

Due to long-term attachment, these elements may get jammed, so you should use a screwdriver, or any sharp edges object two loosen them and then bring them outside of the hole. After you have done this, you will need to buy a new gasket and retainer flip. This is much needed because the previously used parts may get rust, which will not help future use. So once you have obtained the new gasket and retainer flip, you have to replace them with the old ones.

At first, you have to use your fingers and put the gasket as a junction for the plumbing pipe and the bathtub, this will cover up the extra space, and it will make room watertight, in this manner, the water will be directed to the pipe rather than leaking. Then you have to take the retainer flip and place it on the surface of the bathtub. You have to use your hand to make it tight, and in this manner, the attachment will get a frame for applying the screw.

At last, you have to take screws and then attach them to the retainer flip; the retainer flip will fold the gasket and the plumbing pipe tightly connected to the overflow knob of the bathtub. Next, you have to take the overflow knob and reattach it with the bathtub. Thus the overflow of the bathtub can be easily stopped without taking any professional help form the plumber. This will be much beneficial for you DIY works.

Method Two

This method is based on eradicating water overflow in the bathtubs, which do not have any retainer flip. This is important for our readers to have a piece of knowledge about the diversities they can face while working. For this reason, we have stated this method in which the arrangement of the plumbing system is quite different, but the solution of such bathtubs to stop the overflow is quite the same and simplified.

For this process, at first, we have to open the knob of the bathtub, as usual, we will observe that there is only a gasket which acts as the connecting point between the bathtub and the plumbing pipes. So we have to take out the plumbing gasket and then observe the gasket’s condition, if the gasket is not in a safe condition, then we have to change it. After that, we have to place the new gasket at the junction point to hold the pipes tightly to the bathtub.

After installing the gasket, there will remain a gap, and this gap can be minimized using chemical substances. We prefer silicon for this purpose, silicon is highly adhesive, and the attachment of the bathtub and the plumbing pipes will be many firms in this way. You can quickly get hold of silicon form the market, and they are sold in small tubes in liquid forms. After you obtained the silicon, you have to apply the silicon on the wall of the bathtub.

The silicon will be applied firmly, and this will also help reduce the gap created due to the erosion of the ceramic from the bathtub. After you have used the silicon, you should keep the bathtub open to the air for drying purposes. Make sure to stop all water inlet lines in the bathtub while you are performing this process. The water may reduce the adhesive capability if the silicon, and this harms the entire process.

After the silicon has dried, you can quickly get the knob attached to the bathtub, but before that, there is another step that you have to follow. As there is no retainer flip, so you have to sue some extra protection to reduce the leakage and keep attachments sturdy. You must take some plumber’s putty and then apply them around the knob, this will create an airtight situation around the knob, and then you can reattach it using a screwdriver. Thus the overflow can be terminated from the bathtub.


Lastly, we hope that your bathtub’s water overflow can be easily stopped by applying the processes that we have mentioned.
