This means removing faulty faucets or placing them directly should be as easy as ABC, but there are several things people ignore while doing it at home. Therefore, if you want no more leaking taps, no breakages, and longer usage of the system, do not make them at all costs.
1. Not shutting off the water supply

Before removing or installing any tap whatsoever, it is very important that you fully locate where hot and cold water supplies are serviced, then turn off both main taps completely so that no flow can occur thereafter, because anything short of this can result in high-pressure water being splashed around, thus leading to mess inside the room as well as possible damage due to moisture content in the walls.
Make sure the shut-off valves are fully closed and no more water is coming out of the faucet once you turn it on. Use the faucet handle to test this by turning it as far as possible, not just with a quick flick of your wrist. Once the pipes have drained, there should be no flow at all. In case you’re not sure about the location of these switch-off valves, trace backwards from where water is obtained for cleaning to find them. Such manual turn-offs are situated close to the entry point house called Main.
Shut off the water completely and briefly open the tap to release pressure that might have built up in the pipes. Therefore, ensure you cover your sink’s drain with a cloth before doing so, as it can cause serious splashing injuries. You can safely remove and replace an old faucet once you’ve relieved pressure on both lines without concern over sudden jets of water.
2. Using the Wrong Tools
To install a faucet, there are only a couple of special tools that you may not already have in your basic toolkit. When working with the wrong materials, they can easily damage parts of this device, while proper ones allow securing all joints tightly, making one a real professional.
Here are the must-have tools for faucet installation:

Basin wrench: This specialised wrench has a long handle and swivelling jaw that allows you to reach up inside the undersink area and loosen nuts securing the faucet. Regular crescent wrenches don’t work well in the tight space.
Faucet supply lines: Unless you can reuse your existing flexible supply lines, new ones are needed to connect the faucet to the water supply valves. Make sure you have the correct type and length for your specific installation.
Plumber’s putty or silicone caulk: Used to seal the faucet base to the sink or countertop. Plumber’s putty is common for drop-in sinks, while silicone works better for undermount sinks.
- Pipe joint compound or plumber’s tape: applied to threaded fittings to create a watertight seal. Prevent leaks on the supply line connections.
- Groove joint pliers are helpful for loosening old supply lines or tightening new ones.
- Teflon tape is wrapped around pipe threads before installing supply line adapters to prevent leaks.
Safety glasses: Protect your eyes from debris when removing the old faucet.
Gather all necessary tools beforehand so your project isn’t derailed by a missing item mid-installation. You’ll also need common tools like an adjustable wrench, Phillips and flathead screwdrivers, pliers, and a flashlight. With the right gear, you can glide through this DIY project.
3. Over-Tightening Connections

It is important for all connections made during the faucet mounting process to be properly tightened so that there are no leaks or drips later on. However, an installer can easily over-torque the locknuts and supply lines beneath the sink when tightening them up, thereby making cracks in plastic fittings, especially if they use pliers and wrenches for over-tightening purposes or damage the sealing surfaces inside compression fittings.
The trick is to just tighten it enough, but not too much, such that it seals well but does not loosen after some time of usage. Ensure you follow any torque specifications that may be provided with your faucet components. If the fitting is made of plastic, start by tightening it with your hand until it becomes snug, and then add not more than a quarter turn using pliers. For metal compression fittings, tighten only until the connection feels firm; an additional half turn is usually sufficient.
To avoid a slipped joint or cracked component, always use another wrench to support joints and fittings while tightening them. A finger-tightening method does not work on its own as this could allow connections to unscrew slowly over time due to vibrations; therefore, find a balance between too tight and too loose. Things should be snug but not strained. Take your time and inspect everything carefully so that there will be no costly leaks as a result.
4. Skipping the Plumber's Tape

Although it may seem insignificant, having plumber’s tape applied to all threaded connections is integral to the faucet installation process. It is a white, non-adhesive tape that gets stuck around pipe threads, filling up tiny gaps, thus providing smoothness for easy tightening when connecting different parts of the faucet together. This reduces the chances of leaking while assembling or after mounting.
Apply plumber’s tape to threaded fittings connected to female ends at supply line adapters, shut-off valves, and flexible supply tubes, among other places where male-threaded connections need to be tightened down further through wrapping downwards along thread overlap by about one-third distance going towards the end part. A small amount of tape provides inadequate protection, while excess friction results in difficulties during screwing together; thus, we recommend 3-5 layers be wrapped around each thread in most cases.
The tape is compressed to make a waterproof seal and reduce friction when tightening fixtures. Neglecting it will greatly increase the chances of drips and loose connections in the future. Make sure you have extra tape available for loose connections that need rewiring later. Therefore, this cheap accessory should be used as insurance against leaks forever. Don’t miss out on such an easy step that pays off big.
5. Incorrectly Aligning the Faucet

Correct alignment of your faucet with the sink basin is essential for proper functioning and water flow. This will result in an uncomfortable and awkward installation if the faucet is too forward or backward, at too many angles, or not placed centrally. Water may splash out of the sink or spray off-target if the faucet spout doesn’t align with the basin.
Thus, follow any instructions provided with your new faucet about hole locations and positioning carefully to avoid alignment problems, especially for one- or three-hole models whereby the pre-drilled holes in your sink determine placement. After putting locknuts underneath properly placed bases over holes, apply plumber’s putty or caulk around them for watertight purposes.
For widespread faucets or wall mounts, measure carefully and mark drill points following manufacturer templates. To ensure that your new faucet aligns well, cross-check your measurements against their instructions before drilling.
When securing the faucet from above during installation, keep checking its alignment periodically with respect to its location on top of the counter so as to adjust it accordingly until it faces directly into a basin after rotating it side by side in a straight line, ensuring that there are no spaces in between them, before screwing the nuts fully tight once in line. Correctly positioned faucets are what we end up having after properly adjusting fittings while tightening them.
6. Ignoring leak checks

Finally, repeatedly check for drips over several days upon completion of installing your new faucet. This is another critical step that should not be overlooked because even if everything seems tightly sealed at first, vibrations and water pressure might cause joints or fittings to shift slightly, resulting in drips. This way, you can prevent leaks from damaging your home later.
Once the installation is done, turn the water supply back on and inspect all connections for drips and moisture with your eyes. Tighten any loose fittings with pliers. Then leave the faucet running and come back several times over the next few days to double-check again. Over time, you may notice some leaks occurring. It is also a good idea to place boxes or buckets under a fitting overnight in case they start dripping. If connections are dry after an initial check, do not assume they are leak-free.
Consequently, fittings located on supply line connections, plumber’s putty or caulked areas surrounding them, along with those aerators as well as sprayer hose tips, should be checked together with the faucets spout itself until there are no wet spots on any part of them after repeated testing by readjusting those that occur to be doubtful. Do not complete it before you are absolutely certain that there will be no more drips anymore. Take this last step of the leakage checkup seriously since it will guarantee your faucet will not fail for many years to come.
Conclusion
Even if you have never attempted plumbing repairs before, avoiding these pitfalls will help ensure successful faucet installation projects every time. Turn off water shut-off valve lines; utilise the correct tools; tighten fittings gently; apply plumber’s tape; align components properly; and finally, perform leak tests thoroughly. In view of this easy guide, one can confidently go about installing a new faucet.
You can opt to slow down, check again, and consult a professional if you don’t understand. Eventually, any person with resolve can easily do DIY faucet installation with some practice and the right safety measures. You will be an expert in this important aspect of plumbing—having your sink and faucets in good shape for several years.
FAQ About Faucet Installation Mistakes
You now know how to avoid the most common mistakes when installing a new faucet. But problems can still occasionally crop up, even if you follow best practices. Here are answers to some frequently asked questions about troubleshooting faucet installation issues.
What should I do if I accidentally over-tighten a connection?
Tightening fixtures may make you feel like using pliers or wrenches forcefully. In case there is anything that has been screwed too tight, start by trying it gently using your fingers or pliers while giving support to the surrounding joint. Take care not to break the plastic threads, as they are delicate. If the connection spins freely, remove it, then slather fresh plumber’s tape before re-installing without excessive pressure application. On the other hand, if it won’t move at all, this implies that its threads have been damaged, thus requiring the cutting off and replacement of fitting sections only. Prevent such problems by checking how firm they are on each phase of installation and erring slightly on carefulness.
How can I fix a misaligned faucet after installation?
Unfasten locknuts and supply lines under it, but remain ready should it fall from above. Then carefully slide it back into position where necessary once more with you being able to apply caulking around base possibly just removed during last action taken before making this movement possible itself this time round eventually aligning faucet over sink straight away hence retightening everything seems logical here, including turning knobs slowly enough so that they don't snap off or spindle breakage does not occur due to too much force being put into them throughout this process. In the worst situations, you might have to redrill sink holes or even reposition supply pipes for perfect alignment. Remember to always align correctly while tightening during original installation so that it can be avoided in future.
What are the signs that I need to reapply plumber's tape?
After fixing fittings and taps, check if they still drip due to the tape wearing off. Copper or galvanised steel pipes may also develop some small leaks as water eats away at the metal over time. Any instance of leakage has reached a point where it’s necessary to first disconnect, clean threads before applying new tape, and then fix tightly again. For example drips should not be seen on fittings, handles feel damp when turning on/off water or monthly bill suddenly increases because there is some hidden leakage as observed from leaking faucet and blue mold under it. This is a good practice that prevents major leaks by checking connections periodically through home maintenance habits.
Can I use plumber's putty instead of silicone sealant?
For sealing different aspects of the faucet, both plumber's putty and clear silicone come in handy in their own right. Drop-in sinks and faucets mounted on counters may require putty in order to maintain a solid base under them. Undermount sinks need silicones that hold better, creating a gasket between the bottom surface and the faucet's lower part. This type works best for other applications, such as threaded joints. sealing do not equally work well with either one of these materials used specifically, so choose properly your joint compound plus teflon tape whenever dealing with metallic-to-metal connections. Therefore, select suitable glue before connecting everything together. Therefore, buy the correct adhesive during the installation of parts of the systemization plan so that none of these things could go wrong again.
