One of the easiest ways to fix a leaky faucet is to replace the nut. If you don't have a proper tool, you can try hammering the nut. The heat will expand the solid that holds it in place, and the nut will break loose from the housing. You can also use a hairdryer to heat the nut by blowing it around for a few minutes.

The first step is to disconnect the water supply valve below the nut. If this is not possible, you can use a basin wrench or other hand tool to break the nut off. Once you have removed the faucet nut, you can now use a socket wrench or big ratchet to apply more force. Once the faucet is disconnected, make sure to clean up any spilled water or any debris that has accumulated.

To make sure the new faucet will fit properly, disassemble the old one first. Then, disconnect the faucet if it has a sink. Clean the area well with a soft cloth soaked in white vinegar. If the deposits are thick, you may need to apply the solution twice. Then, attach the mounting bolts to the faucet base and lower it into the sink. The plumbing should now descend through the holes in the mounting bolts.

If the nut is stuck, you can use a propane torch or hair dryer. Before you start the flame, ensure that all flammable materials are covered to avoid the risk of explosion. If the nut is stuck and will not come out, you can also use penetrating oil, calcium dissolver, or a lubricant. This will loosen the nut's bond and allow you to remove it.

You can also use a basin wrench to loosen and tighten the sinks for kitchen. A basin wrench has a long handle and pivoting gripping head to reach behind the sink. This tool is specially designed to reach behind the sink and is extremely useful for loosening or tightening mounting nuts on a kitchen faucet. If you have a basin wrench, then you can use it instead of a spanner.

It's also a good idea to plan your replacement during a store's open hours, since you have a 50% chance of needing an additional part. Before beginning the replacement process, remove all items from under the sink. Make sure the faucet is accessible and free of obstacles. You may also have to remove the garbage disposal and soap dispenser if they're in the way. You don't want to accidentally break one of these components.

When replacing a kitchen faucet, the hardest part is often removing the old nut. The faucet's nut is usually seized by mineral deposits from years of moist storage. You may have to dig a little bit and use a basin wrench to free it. Plastic faucet nuts, on the other hand, are not so easy to remove. If you're having trouble finding the nut, try using a flashlight to illuminate the area below the sink.
