Make sure that you stick to the order and have the right tools. Using the wrong tools can do more damage, and make it even harder to do future fixes.

What Causes a Shower Faucet to Leak?

There could be many reasons for this, but for the sake of simplicity, it’s usually due to worn out rubber seals. These are the O-shaped rubber bands that close up the spaces where water can leak out.

Over time, they’re exposed to wearing and being broken down, so they need to be replaced. The good news is that this is relatively easy to do, and doesn’t require you to call in a costly plumber.

Here Are Some Tips before Getting Started

How to Fix a Leaking Shower Faucet DeltaHere Are a Couple of Things You’Re Going to Want to Do before Doing Any Fixing:

  • Get a good cloth without any holes – place this cloth over the drain or plug to stop any falling nuts, bolts or O-rings from going down the drain
  • Shut off your water supply – you might think this is a little too obvious, but I’ve even forgotten to do this and ended up looking like I’ve just got out the swimming pool

These are very common, and it’s the type that I have in my bathroom.

Here are the steps that you need to follow. Before you get started, remember to cover the drain or plug hole with the cloth, and to drain the water from the system (after shutting off the water supply).

Once you’ve done that you can move on to fixing the faucet. Here are the steps you should follow.

Step 1: Get the Tools You’ll Need

How to Fix a Leaky Shower Faucet Single HandleMake Sure You Have the Following Tools Readily Available:

  • Flatbed screwdriver
  • Philips screwdriver
  • Socket wrench (deep-welled) or a cartridge puller
  • Needle nose pliers

Keep these next to you and make sure they can’t fall into the drain.

Step 2: Remove the Faucet Handle

To complete this step, you’ll need to find the screw holding the handle on.

Sometimes there is a removable plate or cap over where the screw is housed.

You can pop the plate or cap out easily by using the flathead screwdriver and remove the screws with the relevant Philips screwdriver.

Make sure you put the screw somewhere where they can’t roll away or slip into the drain.

Step 3: Remove the Faceplate

Shower Faucet FaceplateOnce you’ve removed the handle, you’ll need to take off the faceplate. This is used to cover up the hole in the wall and needs to be removed for you to get access to the pipes behind it.

There will be at least 2 screws that need to be removed. Use the appropriate Philips screwdriver to take these screws out and keep them separate (don’t get them mixed up with the screw for the handle).

Use your hands to wiggle the plate free and remove it from the wall. Don’t use too much force or you could damage the wall or the pipes behind.

Step 4: Take Off the Escutcheon

This is the sleeve that covers the shower valve. You can often remove it by sliding it off, or by unscrewing it.

You should be able to do this by hand. If there is a lot of mineral build-up that’s stopping it from coming off easily, just pour some warm water and vinegar over it.

Wipe away the residue with a cloth, and then try again.

Step 5: Remove the Locking Clip

Not all shower valves have these. You can locate it by looking for a U-shaped clip sticking out the top of the pipe. You’ll need to use the long-nosed pliers or the flatbed screwdriver to release the clip and get access to the valve.

Make sure to put the clip somewhere safe.

Step 6: Loosen and Remove the Regulating Cartridge

Shower Faucet Regulating CartridgeThis cartridge regulates the flow and temperature of the water.

It has a cylindrical shape and there’s a small bit of metal sticking out at the end.

Use the socket wrench and fit it over the end bit, and loosen the cartridge.

Remove the cartridge with the pliers (it might also come out with the wrench).

Step 7: Install the New Cartridge

If you don’t know the make and model, just take the cartridge you removed to the store and get an exact replacement.

Insert the cartridge into its place and use the socket wrench to tighten it in a clockwise direction. Be sure not to make it too tight, or you risk damaging the cartridge.

Step 8: Put the Faucet Together Again

You just need to reverse the removal steps to install the relevant parts again.

Make sure you use the right screws and try your best not to strip the heads of the screws, or you’ll struggle to get them off in the future.

You might also want to consider soaking the different parts of the faucet in a warm water and vinegar mix if they have any lime or mineral build-up on them. Do this before reassembling the faucet.

Step 9: Test the Faucet

Turn on the water supply and give the water a minute to fill the pipes again. There might be an airburst at first, so be ready for that.

If the leak hasn’t been fixed by following these steps, you need to call in a professional to handle it for you.
