You never know when you will need to do some faucet repair in your house. If you have enough knowledge about plumbing, you may try to fix the problem yourself. If a plumber is not available or the problem happens on the weekend, you may decide to take a look at it on your own. When doing so, try to avoid making the same mistakes most people do.
Identify the Kind of Faucet
The first step is to identify what kind of faucet you have in order to get the appropriate replacement parts. This is one of the most common mistake people make: they come to a store for replacement parts not knowing what kind of faucet they have.
There are three principal kinds of faucets commonly installed in our homes. First the compression faucets: the usual ones with two handles, one for hot and the other for cold water. Cartridge faucets come with one or two handles. And also there are ball faucets, which only come with one handle that you move from left to right to get the desired water temperatures.
Turning the Water off
This may sound silly, but yes, a lot of people forget to turn the water off before starting to work on repairing a faucet. Make sure the water gets turned off at the main shut off of the house if there are no shut offs under the sink. Once the water is turned off, drain the leftover water in the faucet pipe by opening it and simply letting the water out. It is also a great idea to put a rag in the the sink hole ,or put in the stopper. This is because most people will take out screws and small parts while disassembling the faucet and are likely to drop them into the sink hole. Losing small parts can only complicate the repair process.
Replacing the Whole Faucet
Believe it or not, replacing the whole faucet is a costly mistake a lot of people are making. With a ball faucet, often the leak is coming from the handle. You don't need to take apart the whole faucet right away. First, just remove the handle. The ball is being kept in place by a locking collar. Tighten it up with a wrench and turn the water back on to see if the leak is still running. If it does, you need to take it out and see what could be wrong with it. A lot of times people don't have the faucet manual to see how it's made inside, and don't even know how to call the parts. To avoid making multiple trips at the plumbing store, taking the whole thing with you to get help figuring out what part needs to be replaced is a good idea.
