Identifying the Problem with Your Bath Shower Mixer Tap

Before embarking on the repair process, it becomes necessary to identify the root cause of the dripping tap. This will ensure that you address the right issue and save yourself time and frustration. In most cases, a dripping mixer tap can be attributed to one of three common culprits: worn washers, loose internal parts, or damaged cartridges.

Worn Washers

Worn washers are often the leading cause of leaks in mixer taps. These small, circular pieces of hardware create a secure seal within the tap, preventing water from escaping and increasing your water bill. Over time, due to regular use and friction, washers can become damaged or worn out, losing their ability to maintain an adequate seal and causing the tap to drip.

Fixing a leaking bath shower mixer tap due to worn washers involves the following steps:

  1. Turn off the water supply.
  2. Take apart the mixer tap.
  3. Remove the outdated washers.
  4. Fit in new washers.

Replacing worn washers effectively helps to prevent leaks, thereby ensuring optimal tap functionality.

Loose Internal Parts

Another possible reason for a leaking mixer tap is loose internal parts. Over time, screws and other components within the tap can loosen, compromising the tap’s functionality and leading to leaks. Recognizing loose internal parts as the source of your leaking tap is vital for thorough repairs.

Once you’ve disassembled the mixer tap (which we’ll cover in a later section), you can use tools like a wrench, pliers, or an allen key to secure the loose internal components. After tightening these parts, you’ll need to assess the tap’s performance and ensure no leaks persist.

Damaged Cartridges

Damaged cartridges are another potential cause of a dripping mixer tap. The cartridge is a crucial component within the tap, responsible for controlling the flow of hot and cold water. If the cartridge becomes worn out or damaged, it can lead to a dripping tap and require replacement.

To install a new cartridge, you’ll need to follow these steps:

  1. Disassemble the mixer tap.
  2. Remove the old cartridge.
  3. Obtain a compatible replacement.
  4. Install the new cartridge.
  5. Reassemble the tap.

Gathering the Necessary Tools and Supplies

Before commencing the repair of your dripping bath shower mixer tap, ensure you’ve gathered all the required tools and supplies, including those needed for the shower head. This will ensure a smooth and efficient repair process, minimizing interruptions and frustration. Some of the tools you’ll need include an adjustable wrench, bath socket wrench, handle puller, and seat wrench. Additionally, you may require plumber’s grease, stem, replacement cartridge, and replacement washers or O-rings.

You can find replacement parts for your leaky bathtub faucet at hardware stores, home centers, or plumbing parts distributors. Having everything you need at your disposal prior to the repair process will save time and increase the chances of success.

Turning Off the Water Supply

Prior to any tap repair, it’s imperative to switch off the water supply to the tap body. This step is essential to prevent water damage and ensure a safe working environment. Failure to shut off the water supply could result in a flooded bathroom and costly water damage.

To turn off the water supply to your bath shower mixer tap, locate the mains water stopcock (usually found under the sink or near the water heater) and turn it off. Once the water supply is shut off, it is important to open the valves on the tap to release any residual water and reduce water pressure from the system.

Disassembling the Mixer Tap

Now that you’ve identified the cause of the leak, gathered the necessary tools, and turned off the water supply, it’s time to disassemble the mixer tap. This process involves removing the tap handle, unscrewing the packing nut, and detaching the cartridge or valve.

In the subsequent sections, we’ll detail each of these steps. Properly disassembling the mixer tap is crucial for accessing and repairing the problematic components. Following the instructions in the sections below will equip you with the necessary knowledge to dismantle your mixer tap and tackle the cause of the leak.

Removing the Tap Handle

The first step in disassembling your mixer tap is removing the tap handle. To do this, you’ll need to follow these steps:

  1. Locate the handle screw, which may be situated on the side or beneath the handle.
  2. Unscrew the handle screw using a flathead screwdriver.
  3. Gently wiggle and pull the handle off.

If the faucet handle is stuck, try using a lubricant or applying gentle heat with a hairdryer to loosen it before attempting to remove it again. Handle removal should be done with care to prevent any damage to the tap or its internal parts.

Unscrewing the Packing Nut

Once the tap handle is removed, you’ll need to unscrew the packing nut. The packing nut is generally situated at the base of the tap, close to the water supply pipes. Use a wrench or adjustable spanner to unscrew the packing nut by turning it counterclockwise.

After removing the packing nut, the cartridge or valve will be revealed. This will allow you to access the problematic components and proceed with the repair process.

Detaching the Cartridge or Valve

With the packing nut removed, you can now detach the cartridge or valve. Depending on the make and model of your tap, the type of cartridge or valve utilized may vary. To remove the cartridge or valve, use pliers or a cartridge-pulling wrench (which can be acquired from a hardware store).

Once the cartridge or valve has been removed, inspect it for any signs of damage or wear. If necessary, repair or replace the problematic components as outlined in the following section.

If you're experiencing a loose faucet on your granite countertop, it's essential to address the issue promptly to prevent further damage. Knowing how to tighten a faucet on a granite countertop can save you from potential leaks and a wobbly fixture. Start by turning off the water supply to the faucet and removing any decorative caps or handles. Use a wrench or pliers to tighten the mounting nut beneath the countertop, ensuring a snug fit. Be cautious not to overtighten, as this could damage the granite. Once you've secured the faucet, reassemble the handles and caps, and turn the water supply back on.

Once the old washers are removed, install the new ones in their place, ensuring they are properly aligned and seated. After installing the new washers, reassemble the tap headgear or cover by securing the screws and carefully placing the cover back in position.

Tightening Loose Internal Parts

If loose internal parts are causing your leak, you’ll need to tighten them to restore the tap’s functionality. With the mixer tap disassembled, use an appropriate tool (such as a wrench, pliers, or an allen key) to secure the loose internal components.

After tightening the loose parts, assess the tap’s performance by activating the water supply and inspecting for any leaks or other irregularities. If the tap is still leaking, you may need to explore other potential causes, such as:

  • damaged cartridges

  • faulty seals
  • corroded pipes

Installing a New Cartridge

If a damaged cartridge is the source of your leak, you’ll need to install a new one. Begin by removing the old cartridge using pliers or a cartridge-pulling wrench. Once the old cartridge is removed, obtain a compatible replacement from a hardware store or plumbing parts distributor.

To install the new cartridge, follow these steps:

  1. Ensure the cartridge is oriented correctly.
  2. Slide the cartridge into the faucet body.
  3. Secure the retaining clip by aligning it correctly and pressing it into place.
  4. Replace the handle by aligning it with the screw hole.
  5. Securely tighten the screw using a flathead screwdriver.

Reassembling the Mixer Tap
