Soldering Tool
To replace washer type faucets shut off the water supply of the entire house. Then remove the faucet handle by turning the screw clockwise. This can be done with the help of screw driver. After that remove the stem and examine the threads. If they are corroded or worn out then take them to a retailer. If the stem is dirty clean it. If the brass screws are corroded you can replace them too. Take a look at the washer seat. If they are worn out you can reface them using seat dress tool. As faucets are available in various shapes and sizes do remember to install the correct faucet washer. Some stems use O ring. In such cases replace the rings too.
If it is a noisy faucet then the problem may be in the loose washer. In such cases remove the faucet and tighten the washer. The faucets might be noisy due to poor design and construction also. When threading the stem back in faucet body try moving the stem up and down. If it moves then entire faucet may have to be replaced.
In washer-less faucets you will need to replace the working parts. Pre-packaged kits are available. Just follow the instructions carefully.
The diaphragm type faucets are similar to washer type faucets. Here instead of washer you will have a disc. To replace these you need to remove the handle and the stem. If the rubber diaphragm does not come out with the stem it may be still inside the faucet. In such cases, use pliers to peel it from the faucet. Then replace the diaphragm around the disc.
In ball type faucets there will be a ball inside to control hot and cold water. Due to improper ring tension the handle may be leaking. In these cases you will have to replace all the working parts of the faucet. You may need the help of spanner or hex wrench. If the ball is coated with scale you will need to clean it.
For cartridge type faucets you will need to remove the handle. Then there will be a swing spout which needs to be removed. Using a screw driver pull out the retainer clips and then cartridge can be pulled with the help of pliers. While replacing the cartridge, use silicon-grease to lubricate the cartridge.
Remember to :
Always read the installation manual. While soldering copper pipes make sure you remove the cartridge. This is because the excess heat generated may damage the smaller parts in faucet body. Clean out the faucet body with a wet cloth after you finish soldering to remove the flux. Always have an access panel on the opposite wall behind the faucet. This will make it easier to install a new faucet in the future.
