Replacing a bathroom faucet is one of the most common plumbing tasks. Over time, even a high-quality faucet wears out: it starts leaking, doesn't regulate the temperature properly, or switches from shower to faucet. Many people call a professional for this, but in fact, you can do the job yourself, saving time and money.
How to choose a new faucet
Before going shopping, it's important to decide on the type of faucet. Models with a long spout and a shower diverter are typically used in bathrooms. Pay attention to the body material—brass faucets are heavier and more durable than silumin ones. Also, check the package contents: the box should include eccentrics, decorative caps, and gaskets.
If you already have a faucet installed, measure the center-to-center distance between the connections—it could be 100, 150, or 200 mm. This will help you choose the right model without the need for unnecessary adapters.
- Brass faucets — last longer, but are more expensive.
- Silumin models - light and cheap, but fragile.
- Ceramic cartridges - reliable, but sensitive to water quality.
Preparation for work: tools and materials
To replace a faucet, you'll need an adjustable wrench, pliers, screwdrivers, and teflon tape or plumbing linen. WD-40 is also helpful—it can help loosen stuck nuts.
Before starting work, turn off the water at the standpipe or at the faucet connections. Open the faucet to relieve any residual pressure. Place a basin or bucket under the sink—a little water may spill out when you unscrew the connections.
Removing the old faucet
First, treat the threaded connections with WD-40 and wait 10-15 minutes. Then, using an adjustable wrench, carefully loosen the nuts securing the faucet to the eccentrics. If the nuts are stubborn, don't apply excessive force—it's better to treat them again with WD-40.
Once the faucet is removed, unscrew the old eccentrics. If they are stuck, use pliers or a pipe wrench. Be careful not to strip the threads on the connections.
Installing a new faucet
Start by installing the new eccentrics. Apply 3-5 turns of FUM tape to the threads and screw them into the connections. Align the eccentrics with a level so that the distance between them matches the faucet. Screw on the decorative caps.
Install the faucet onto the eccentrics and tighten the nuts. Don't overtighten them—check for any distortion first. Then connect the shower hose and install the shower head onto the holder.
- Use the gaskets included in the kit to ensure a tight seal.
- Check all connections for leaks.
- Don't forget about the RCD - it's important for safety.
Common mistakes and how to avoid them
One of the most common mistakes is overtightening the nuts. This can lead to stripped threads or damaged gaskets. Tighten the nuts until they stop, but do not apply excessive force.
Another problem is improper installation of the eccentrics. If they are not aligned properly, the faucet will be crooked, and the decorative trims will not fit properly against the wall. Always use a level during installation.
Replacing a faucet is a simple task if you approach it responsibly. Following the instructions, you can complete it in 1-2 hours, even if you have no previous plumbing experience.
