If you've ever replaced or installed a new mixer tap in your kitchen or bathroom, you might have encountered an annoying issue shortly thereafter: the tap begins to drip, despite being brand new. This can be puzzling and frustrating, especially when you expect freshly installed fixtures to work flawlessly. This post aims to unpack the common reasons behind this issue, help you identify potential solutions, and advise on when it might be time to call a professional.
An Introduction to Mixer Tap Dripping
A dripping mixer tap isn't just a minor annoyance; it can lead to wasted water and increased utility bills. It’s a common issue that many face post-installation and often, the cause boils down to either an installation mishap or a fault in the tap mechanism itself. Understanding why this occurs is your first step towards a solution.
Installation Issues
Improper installation is the most frequent culprit for a dripping mixer tap. This doesn’t necessarily mean a mistake was made, but there might be steps overlooked which can lead to issues.
1. Incorrect Washer Placement
The washer, a small but crucial component, seals the connection between your tap and the plumbing. If this isn’t fitted correctly, small drips can begin to appear almost immediately after installation.
2. Pipe Thread Problems
Connection threads on the supply pipes must be adequately sealed. A common mistake is not applying enough thread tape or plumber's putty, or over-tightening, which stresses the joint.
3. Loose Fittings
All connections should be secure, but overtightening can be just as problematic as not tightening enough. A snug fit ensures no movement, which is essential to prevent drips.
Quality of Tap
Not all mixer taps are created equal, and sometimes the internal components might not match the standards required for robust, long-lasting operation.
1. Faulty Cartridges
The cartridge controls the mix of hot and cold water in your mixer tap. A defect here can cause not just dripping but also fluctuations in water temperature.
Diagnosing the Issue
Before you can fix a dripping mixer tap, you need to identify where the problem lies. Start by checking the most obvious external factors like loose handles or connections. If these seem intact, the issue might be internal.
1. Check the Handle
Sometimes the handle might not be fitted correctly or may have loosened slightly, which could cause dripping.
2. Examine the Connections
Ensure all connections, including those at the base of the tap where it meets the sink, are tight and secure.
DIY Fixes
If you’re handy with tools and feel confident, here are some steps you can take to attempt to fix a dripping mixer tap:
1. Tighten the Connections
Use a wrench to gently tighten the connections. Remember, the goal is firm but not overtightened.
2. Replace the Washer
If the washer appears worn or incorrectly placed, replacing it can resolve dripping issues. Washers are inexpensive and available at most hardware stores.
3. Apply or Reapply Thread Tape
Unscrew the problematic connection, apply fresh plumber's thread tape, and reassemble, ensuring everything is aligned correctly.
When to Call a Professional
If you’ve tried the above fixes and the tap continues to drip, or if you are not confident in your ability to disassemble and reassemble the tap, it might be time to call a professional. A qualified plumber can diagnose issues that might not be immediately apparent to the untrained eye.
1. Complex Internal Issues
If there’s a deeper mechanical problem, like a faulty cartridge, it’s advisable to get professional help, especially to maintain any warranty on the tap or avoid causing further damage.
2. Extensive Water Damage
Sometimes, a simple drip can indicate more severe issues. If you notice water damage beneath the sink or the fittings, a professional can assess the extent and recommend appropriate actions.
Long-Term Prevention
To avoid future issues with new installations:
1. Choose Quality Hardware
Opt for reputable brands and high-quality materials that promise durability and come with good warranties.
2. Follow Installation Guidelines Precisely
Even if DIY isn’t new to you, following the manufacturer's instructions carefully can prevent many common issues.
Conclusion
A dripping mixer tap after installation can certainly be an annoyance, but often, the solution is within reach. Start with simple checks and fixes, like ensuring everything is tight and correctly positioned. For those less inclined to DIY or when faced with persistent issues, don’t hesitate to call in a professional. Proper installation and choosing quality fixtures can help avoid these problems from the outset, securing peace of mind with your plumbing projects.
Remember, taking action at the first sign of a problem not only preserves the integrity of your new tap but also saves water and reduces the risk of more severe issues down the line.
