A leaky shower head is something we all have or will experience at some point.

But worry not! Most causes for a leak in the showers head or faucet are actually quite simple and easy to fix. With a bit of context and guidance you may very well be able to fix the problem yourself, saving you cash and putting an end to the frustration.
Let’s discuss a few easy steps on how to fix a leaky shower faucet and kick this problem into the past! It’s time to make it look like a brand-new shower faucet.
How to Fix a Leaky Shower Faucet?
Tools and Materials You Will Need
- A 4 in 1 screwdriver
- A pocketknife
- An adjustable wrench
- A handle puller
- A pair of pliers
- Some grease
- A new cartridge (Only if the cartridge is your leak source)
Unclogging the Shower Head Holes
A clog in the shower heads holes is a common cause for leaks. The water cannot escape through all the needed holes and as such is forced out the sides, which can also cause damage here that adds to the leak.
To begin, turn off your water that feeds the bathroom area
Now remove the faceplate of the shower head. If the faceplate is fixed on permanently, remove the entire shower head.
Place the face or shower head completely in vinegar and salt. This will eat away at whatever lime or calcium build up exists in the holes. Let it soak for around 7 – 9 hours.
Once done, use a needle to manually remove whatever junk is still in the holes. Now give the faceplate a good old scrub.
Once all of this has been done, place the shower head or faceplate back as you found it and turn on the water supply to the shower again. Turn the faucet on and test to see if the leak has been taken care of or not.
Putting a New Washer on – Step by Step
The next step to solving the problem if unclogging the holes didn’t work, is to get rid of the old washer in your faucet or shower head that exists to make it water tight, and pop a new one in.
First off, check what kind of faucet you have. If it’s a two-handed faucet for hot and cold water, feel the temperature of the water leaking out to figure out which faucet to address. If you happen to have a mono hand faucet, the replacement should then happen in the shower head instead.
If Replacing the Shower Head Washer
If you have determined that it is in fact the showers headpiece that needs a washer replacement, begin by turning off the water to your bathroom area again.
Once done, carefully remove the shower head from its connecting arm by locating the collar nut and loosing it. This nut will be found at the visible join between head and arm.
Once it’s off, find the iron swivel bearing that is used to turn your showers headpiece about. It looks exactly like what you’re imagining right now, a metal ball that can move around. The washer will be directly under the swivel ball-bearing.
Now simply pop off the old washer. Source a replacement washer that is of the exact same size and thickness and pop that on in the old washers place.
Now grease the washer and swivel a little. Once done, simply replace the shower head and tighten the collar nut again. Turn on your water supply and give it a good old test.

If You Have Determined One of Either of Your Cold or Hot Taps Is the Problem
In this case, turn off your water to the bathroom.
Locate the screw on the faucet which will either be on the nose or the side. Keep in mind it may be hiding behind a little screw cap. If so just use a pocket knife to pop the cap. Loosen the screw and take it out.
Now grab the handle grabber/puller, and give it a go. Once you have removed the faucet handle you will notice a sleeve protecting the stem and a trim with that. Remove these gently.
You should then see what is know as a hex nut. It’s a six sided nut commonly used in plumbing fixtures. You will need a deep socket wrench to remove this nut. Once you have, simple pull off the old washer and replace it with a newer twin.
You can use this opportunity to replace the other flat rings and so forth if you have replacements handy and deem it Necessary.
Once completed, replace the sleeve and trim, then the handle, and then the screw. Ensure it is properly tightened. Now turn your water on and test out your handiwork.
Sorting Out a Faulty Diverter Valve
If the previous guides did not produce results, you have to either clean or replace your diverter valve. This is the valve that determines if the water flow is going to your bathtub or shower. Once it’s got too much dirt on it from sedimentary build-up or is damages it will start to leak.
As before, the first step should always be to turn off the water supplied to your bathroom. Just turning off the showers water supply will not cut it in this case.
Locate the screw that keeps your faucet attached to its stem. It will either be on the face or side of the faucet handle. Loosen the screw and remove it.
Use a faucet grabber to pull the faucet off of its stem now. Take care with this so as not to scratch or damage the handle.
Once the step is exposed remove the sleeve and trim, then the hex nut, and pull the diverter valve out.
Using a course brush and vinegar, give the diverter valve a proper scrub-down. The vinegar will help to remove any lime scale or sediment build up on the valve. Also check for permanent damage on the valve. If any damage can be seen, simply replace the valve with a new one that is identical in every way.
Place the cleaned or new valve back in to the stem and replace the hex nut. Once the hex nut is tightened, put the sleeve and trim back on too. Now pop your faucet handle back on and secure its screw back into place tightly. Turn the water supply on again and check to see if the problem has been sorted out.

Installing a New Cartridge Valve
Shower faucets that consist of only one handle to control water temperature and velocity use a cartridge valve inside the faucet stem. When this is worn out or broken it causes leaking, the next step is taking on this bad boy. Relax though, it’s not rocket science!
Ensure as always, that the water to your bathroom has been turned off. Forgetting to do so could cause you untold headaches!
Take off the faucet head by loosening and removing the screw that is either on its face or side. Use a handle puller to grab and remove it. Be sure to do this as gently as possible to avoid unnecessary damage to the handle or faucet stem.
You will now see a stop tube. Remove that, and the cartridge retainer clip. Then you can slide off the washer. Once these are off you will observe the cartridge.
Here comes the fun part. Most cartridges are set to simply be turned and pulled when removing. This needs to be done carefully though, and in some cases with a specialised tool called a cartridge puller. This can be purchased separately but often come with a new cartridge too. Use either the cartridge puller or a set of pliers to gently twist the cartridge anticlockwise and pull it out.
Now do the same thing in reverse with the new cartridge. Place it in and gently twist it clockwise until you can feel it’s secure.
Replace the washer, cartridge retainer clip and stop tube. Then replace the faucet handle. Now you can turn your water on and have a look to see if the leak has been dealt with.
