Do you hear a constant dripping coming from the kitchen or bathroom? Your water tap could be leaking. And while your first thought may be to call a plumber, fixing the leak isn’t actually as difficult as it sounds.
In our article, we share some causes behind the leak, the implications of not fixing a leaking tap promptly, and 7 easy steps for fixing it with tips included!
Causes of a Leaking Water Tap
There are various reasons for a leaking water tap including broken or damaged parts and high water pressure.
Here are some key parts of a water tap:
Broken or loose o-ring
The o-ring is a thin ring-shaped rubber piece that serves as a watertight seal to prevent the tap from leaking. When this ring breaks or becomes loose, water may start to drip.
Broken or poorly installed washers
The washer helps to regulate the flow of water. Due to wear and tear or corrosion, the washer may break, causing a leak to occur.
Poor installation or a mismatch in washer size may also result in leaks.
Damaged or worn-out cartridges
Tap cartridges help to regulate the pressure and temperature of the water output. When the cartridge experiences wear and tear or external damage, water leakage may occur.
Damaged or corroded valve seat
Water dripping from the spout could be a sign that the valve seat, which connects the tap to the spout, is damaged or corroded.
Overly high water pressure
If the pressure is too high, there may be a buildup of excess water in the pipes. This water may try to find an outlet to escape from, resulting in a leaking tap.
Implications of Not Fixing a Leaking Water Tap
At first glance, a leaking faucet may seem like a small issue. However, it can cause various problems if not fixed promptly, including mould growth, water damage and water wastage.
1. Mould growth
Mould can form over time if your water tap is left dripping. This can spread to your walls and floors, and may even cause allergic reactions such as sneezing and skin and eye irritation.
2. Water damage
Leaving a small water leak unchecked for an extended period of time can result in damage to your furniture and flooring. This is especially so for items made of wood as they tend to absorb moisture.
3. Water wastage
Did you know that a single leaking tap can waste at least 400ml of water each day? This amounts to 146 litres a year! On top of wasting water, this can cause a hike in your monthly utility bills.
How to Fix a Leaking Water Tap
If you’re thinking about fixing a leaking tap on your own, here are 7 easy steps and the tools you’ll need for the job.Tools you need
• Adjustable spanner
• Screwdriver (flat-head and cross-head) and/or Allen key
• New parts (e.g. tap cartridge, washer or o-ring)
• Cloth (optional)
Step 1: Turn off the main water supply
The first and most important step in the process is to turn off the water supply to your house. This ensures that you don’t accidentally flood your kitchen or bathroom.
Once you’ve turned the water off, check by turning the tap on. If no water flows out, you’re ready to begin!
Step 2: Remove the handles
After turning the water off, it’s time to remove the handles. The method of removal will depend on the type of fixture you have.
• Handles with caps
Some tap handles have caps that hide the screw underneath. Simply use the flat-head screwdriver to remove the caps and unscrew the handle.
• Handles with grub screw
These handles require an Allen key to loosen the grub screw. After unscrewing, you can pull the handle off.
• Handles with levers that unscrew
Some taps come with levers that can be unscrewed to reveal another screw underneath.
• Handles that pull off
These tap handles don’t have screws and can simply be pulled off. If you’re having difficulties doing this, try using a flat-head screwdriver to pry it off.
Step 3: Remove the cartridge
Once the handles have been removed, you’ll see the cartridge (or tap stem). While some can be popped off, others may require a spanner to help with unscrewing.
You may want to place a cloth below the cartridge before removing it as some excess water may leak out.
Step 4: Inspect the parts to find the cause of the leak
Now that the respective parts have been removed, it’s time to find the cause of the leak. Carefully inspect each part for damage or corrosion, or observe if any of them are broken.
If they’re in good condition, the cause of the leak could be high water pressure.
Step 5: Fix the issue
If a part is damaged, corroded or broken, replace it with a new one. For washers or o-rings, it’s essential to ensure that they’re an exact fit to prevent any leakage.
Alternatively, if the cause of the leak is high water pressure, locate the water pressure regulator and adjust it slowly.
Step 6: Reassemble the tap
After you’ve replaced the necessary parts, reassemble the tap by reinserting the cartridge followed by the handle.
Step 7: Turn on the main water supply and check for leaks
Once the tap has been fully reassembled, the last step is to turn the water supply back on and check for any leaks.
If necessary, adjust the water pressure regulator again until you reach the optimal level.
Tips for Fixing a Water Tap Leak
To ensure that you fix the leak quickly and smoothly, here are some tips to help you out!
Ensure that the drain is plugged before you start
