common mistakes people make when fitting sink taps

Fitting sink taps may seem like a straightforward task, but many individuals encounter issues that could have been easily avoided. In 2026, with the rise of DIY culture, it is crucial to be aware of common pitfalls that can lead to leaks, inadequate fitting, or even damage to your plumbing system. This article will guide you through these mistakes and offer practical advice on how to ensure a successful installation.

Ignoring the manufacturer's instructions

One of the most frequent mistakes people make is not reading or following the manufacturer's instructions included with their sink taps. Each model can have specific requirements, from the size of the holes in your sink to the type of fittings necessary for a secure installation. Skipping this essential step can result in improper fitting, leading to leaks or a malfunctioning tap.

Neglecting to check water pressure

Before installing your new taps, it is vital to check the water pressure in your home. Many people overlook this step, which can lead to poor performance of the tap. If the water pressure is too high or too low, it can affect the functionality of your taps and may cause damage over time. Use a simple pressure gauge to check the pressure levels and consult a professional if adjustments are needed.

Failing to measure correctly

Incorrect measurements can cause significant problems when fitting sink taps. It is essential to measure the distance between the holes in your sink accurately to ensure that the new taps will fit properly. Many people assume that all taps fit standard sizes, but this is not always the case. Take your time to measure carefully and double-check your dimensions to avoid unnecessary hassle during installation.

Using the wrong tools

Using inappropriate tools can lead to damage to your taps or sink. For instance, using pliers on the tap can scratch or dent the finish. Instead, invest in a proper wrench that fits the nuts and fittings you are working with. Additionally, having the right size screwdrivers and adjustable wrenches on hand will make your fitting process smoother and safer.

Neglecting to turn off the water supply

This might seem obvious, but many people forget to turn off the water supply before beginning the installation process. Not only can this lead to a messy situation with water spraying everywhere, but it can also increase the risk of accidents. Always remember to shut off the main water supply and let the taps drain before starting your work.

Over-tightening fittings

When installing sink taps, it is crucial not to over-tighten the fittings. Many believe that the tighter the fitting, the better it will hold, but this is not the case. Over-tightening can lead to damaged seals and, ultimately, leaks. Instead, tighten the fittings until they are snug and secure without exerting excessive force.

Not using plumber's tape

Plumber's tape, also known as PTFE tape, is essential for ensuring a leak-free connection between threaded fittings. Many DIYers skip this step, assuming that the fittings will be tight enough. Failing to apply plumber's tape can lead to slow leaks that may go unnoticed until significant water damage occurs. Always wrap the threads of your fittings securely with tape to create a watertight seal.

Neglecting to test for leaks

After you have fitted your sink taps, the work is not over. Many people forget to test for leaks before completing the installation. Turn the water supply back on and run the taps while checking for any leaks around the fittings. If you notice any, turn off the water supply and make the necessary adjustments before using the taps regularly. This simple step can save you from future headaches and costly repairs.
