1) Turn off the water supply to your shower.
A worn-out rubber washer could also be the cause of a leaky shower head. The washer or “O ring” can begin to crack over time and allow water to seep through. You can solve this problem simply by replacing the washer. To do this, start by cutting off the water supply to your bathroom, which can be found near your shower or in your basement.
a. You can maintain these rings by applying lubricant
b. If you have a compression faucet, meaning two different faucet handles to control the hot and cold water, you will need to put your hand underneath to determine if the leak is coming from the hot-water valve or the cold-water valve. By doing this, you can know which faucet you need to focus on.
2) Determine which rubber washer you should replace
There are two rubber washers you can decide to replace: the one in your shower head or the one in your shower faucet. Also, your shower faucet type will determine the type of rubber washer you need to replace. A compression faucet (or a two-handle faucet) will require replacing the rubber washer in the faucet. However, for a single-handle faucet, you might likely need to change the rubber washer inside the showerhead.
3) Replace the rubber washer in your shower head
Start by taking the showerhead apart. The method used in doing this will depend on the make and brand of the showerhead, but usually, you will find a collar nut attached to the shower arm. The collar nut has the look of a regular metal nut, but it is longer. Its neck (or collar) is about 1.5 times its diameter.
1. Hold the fixture down with a rag and use a wrench to loosen the collar nut so that the showerhead is separated from the shower arm. When this is done, look underneath the shower head’s swivel, and you will find the rubber washer.
2. The swivel ball is a metal fixture that is directly attached to the showerhead, and it allows the movement of the showerhead. It is a metal fixture that looks like a big nut with a metal ball on the end. It can also be rotated like a showerhead.
3. After you have found the rubber washer, you can then replace it with a new rubber washer, similar in style and size. A perfect replacement is one that has a striking resemblance to the old one. Also, the new washer should have the same thickness to prevent leaking over time.
4) Replace the rubber washer in your faucet
Remove the faucet handle by unscrewing it. You can determine the faucet you should be working on by studying the temperature of the leaking water.
1. This screw might be easy to see or hidden behind a cover cap, depending on the make and brand of your faucet. Older model faucets usually have these screws exposed on the side or front of your faucet, while newer models usually require that you lift the cover cap to expose the screw.
2. When you have removed this screw, you can proceed to pull it off the faucet body by pulling the handle hard. To do this, you may need a faucet puller. After taking the handle off, remove the trim and sleeve that covers the faucet stem, after which you use a deep socket to unscrew the faucet stem. A hex nut holds down the faucet stem, so a deep socket will be needed to unscrew the hex nut. The hex nut is a nut with six sides, and a shower valve socket wrench can easily loosen it.
3. When all this is done, you can replace the rubber washer. If you’ve bought the faucet washer kit, you can also replace the flat washer at the end of the stem and the seals.
5) Reassemble the shower parts and check to see if the problem’s fixed.
After you have changed the rubber washer in the showerhead, connect the showerhead back to the shower arm and put on the water supply again so that you can see if the problem has been taken care of. Don’t try to overtighten the showerhead, just screw it on snugly.
After changing the rubber washer in the shower faucet, you should put your faucet back together, starting from the faucet stem. Apply some plumber’s grease on the threads where the stem will go and screw the stem back on. Replace the handle to its original position, but don’t screw until you are sure that the leaking shower head has been fixed after you have turned your water supply back on.
