Identifying the Problem

A leaking delta shower faucet can be very frustrating. The constant drip sound can disrupt your peaceful mornings and also hike up your water bill. Fixing it imminently is crucial, but before that, you need to identify the problem. A host of reasons can lead to faucet leakage, but with a little troubleshooting, you can fix it yourself. Here are a few common problems that you might encounter with your delta shower faucet.

The Cartridge Valve

The cartridge valve is one of the essential components of a delta shower faucet. As it controls the water flow, any malfunction can cause leakage. If you suspect the cartridge valve to be the reason behind the problem, you should start by turning off the water supply and removing the faucet handle. Once you expose the cartridge valve, check for any damage or wear and tear. It’s best to replace the cartridge valve if you notice any signs of damage.

The Rubber Washer

Another common cause of delta shower faucet leakage is the worn-out rubber washer. The washer creates a watertight seal for the faucet handle, and if it damages, you will notice constant dripping. If you know how to use a wrench, you can quickly fix the problem by replacing the rubber washer. Ensure that you turn off the water supply and unscrew the faucet handle to get access to the washer. Gently remove it with the help of a flat screwdriver and replace it with a new one.

The O-Ring

The O-ring is a small rubber ring around the valve stem that helps in securing the faucet handle. Its wear and tear can lead to faucet leakage. If you suspect the O-ring to be the culprit, you can visually inspect it for any damage. If it’s visible, use a screwdriver to remove the old one and replace it with a new one. If it’s challenging to access it, you may consider seeking professional help

The Showerhead

It may seem surprising, but sometimes the problem is not with the faucet but the showerhead. Build-up of mineral deposits and dirt can interfere with the water flow leading to leakage. To check if the showerhead is the problem, remove it and check for any build-up. Soak it in vinegar for a while to loosen the debris and clean it with a brush. Reattach the showerhead, and the leakage may stop.

Faulty Installation

If it’s a new installation, then the problem may be in the installation itself. A poorly installed delta shower faucet can cause constant leakage. If you are not sure about the installation, it’s best to seek professional help. They can inspect it for any faults and make the necessary repairs.

Identifying the cause of delta shower faucet leakage is the first step in fixing the problem. Most problems are easy to fix and require minimal tools and time. However, if you are not sure about your plumbing skills, it’s best to seek professional help. A poorly executed repair can lead to more significant issues and expenses.

Turn off Water Supply

When you notice a leak from your Delta shower faucet, your very first course of action should be to turn off the water supply to the shower. This will allow you to work on the faucet without worrying about water spraying everywhere. Turning off the water supply will also prevent further damage to your bathroom floor or wall. It is essential to find the water shutoff valve before you begin making repairs. In most cases, the shutoff valve is located in the basement, utility room, or near the water heater.

If you don’t know where to find the shutoff valve, you can seek professional assistance to avoid any potential damage to your plumbing system. If you prefer to locate it yourself, try to trace the pipes leading to your shower. The shutoff valve will typically be located where the pipes come into your home. Once you have located the valve, turn it clockwise to shut off the water supply to your shower.

After turning off the water supply, open the shower to let any remaining water run out of the pipes. This will prevent any dripping of water that could happen as you work on the valve. Observe the shower as it runs, and make sure that no water is coming out. If you notice water still dripping from the faucet or showerhead, it means that you have not turned off the valve correctly, or you may have a faulty valve.

Turning off the water supply is an essential and straightforward step that will save you time, effort, and money in the long run. Remember that failing to turn off the water supply increases the risk of water damage to your bathroom walls, floor, and even your plumbing. Once you shut off the water supply, you can now proceed to the next step of fixing a leaking Delta shower faucet.

Dismantle the Faucet


Dismantle the Faucet

After turning off the water supply, you can now dismantle the faucet. Remember that this process can be a bit tricky, so be patient. Below is a detailed guide on how to dismantle your Delta shower faucet:

Step 1: Remove the Handle

Use a flathead screwdriver to remove the screw cap on top of the handle. Once you have removed the cap, unscrew the handle by turning it counterclockwise. If there is any resistance, wiggle it back and forth until it pops off.

Step 2: Remove the Trim Sleeve and Screw

After the handle has been removed, unscrew the trim sleeve that surrounds the stem by twisting it counterclockwise. Once the trim sleeve is removed, take out the screw that holds the faucet in place using a screwdriver.

Step 3: Remove the Cartridge

The cartridge sits just behind the screw you just removed. It can be removed by gently pulling it out with a pair of pliers. Be gentle as you do so, as the cartridge might be stuck. If it seems to be stuck, wiggle it back and forth a bit until it comes loose.

At this point, you should examine the cartridge for any signs of wear or damage. Look for cracks, corrosion, or any other damage that may be causing the leak. If the cartridge is damaged, it may need to be replaced. If it looks good, however, you can simply clean it and replace it.

Step 4: Clean the Cartridge and Valve

Use a soft-bristled brush to clean the cartridge and valve body of any debris or buildup that you see. Pay special attention to the O-rings, as these are usually the culprits behind leaking shower faucets. Once they are clean, apply some silicone grease to them to help them slide back into place smoothly.

Step 5: Reassemble the Faucet

Now that you have dismantled and cleaned the faucet, it is time to reassemble it. Place the cartridge back into the valve body, making sure it is snug. Reinsert the screw and tighten it using a screwdriver. After that, slide the trim sleeve back into place and twist it clockwise to keep it secure. Finally, reattach the handle by screwing it back into place and replace the screw cap by snapping it back onto the handle.

By following these simple steps, you should be able to fix your leaking Delta shower faucet without having to call a plumber.

Replace or Repair Parts

Step 2 – Attach the Shower Head

Most Delta shower faucets come with a separate shower head that needs to be attached to the faucet. Before you attach the shower head, wrap the threads of the faucet with plumber’s tape to create a tight seal.

Next, screw the shower head onto the faucet in a clockwise direction, making sure it’s tight enough to prevent any leaks.
