The parts that commonly break in a kitchen faucet are the inner parts; in fact some of the components are actually meant to fail, for a good purpose. Very much like the brass or bronze bushing on motorized equipment, they are engineered to fail first to avoid it from destroying the more expensive shafting. In kitchen faucets, to preserve the main casing, the stem is constructed using a much softer metal such as brass. While we open and close the faucet, the brass stem gradually wears, little by little, till the whole tread finally vanish and can no longer apply pressure to the rubber seal no matter how much you turn it. When this happen, a leak appears, and to fix it, the stem is required to be replaced with a brand new one. Normally you can find a replacement faucet stem at a very low price, close to less than $10, much economical as compared to if you will buy the entire faucet.
Another kitchen faucet components that constantly wears or break is the rubber seal. Constructed of flexible type soft rubber they are used to seal the valve mechanism within the faucet. Once you tighten or rotate the knob to close it, the stem pushes it against the valve seat. Each time you close the faucet, the rubber seal is sandwich in between the stem and the valve seat. Imagine how many times you do this in a day. At some point, the rubber seal may lose its rubberize characteristics and become brittle, breaking into smaller portions.
As soon as this happens, a leak will appear and regardless how we tighten the knob it will still leak since there’s no more rubber seal to close it. Changing the rubber seal is quite simple, they are usually fitted to the end of the stem, kept in place by a small screw. In order to restore it you have to dismantle the top part of the faucet and take out the stem. After that, remove the screw that is keeping the rubber seal with a screwdriver and then put the new rubber seal and put back the screw to hold it back in place.
Normally when there is a faucet drip, replacing the rubber o-ring seal will fix it. Some people also do this mainly because they want to save money, changing just the rubber seal is cheaper as opposed to buying the complete set of repair kit. But sometimes it is not the only one contributing to it; it also may possibly be the stem or a cracked spring and valve seat. So, to make certain that you really repair it, most people replace all the internal components together with the stem and the rubber seal by using a kitchen faucet maintenance kit. Faucet restoration kits normally comprise of the stem, rubber seals or o-rings, seats or valve seats, spring, a special wrench, and in some cases it also includes the knob. In some models, an instruction guide book is also included, complete with an exploded view and detailed instruction on how to dismantle and put together the kitchen faucet.
Additionally, there are faucet parts that you can purchase to resurrect your kitchen faucet to its original or shinny look. These parts are referred to as overhauling kit. Not like repair kits which include internal parts, overhauling kit features the external parts or the combo of the two. Normally, it contains a pair of fresh new knobs and trims with various finish like chrome, brass and gold plated finish. If you just renovated your kitchen, you can also change the appearance of your faucet to blend with the new dcor instead of shopping a completely new set of faucet which is very costly not to say the labor expenses.
When purchasing a kitchen faucet replacement parts it is encouraged to purchase an additional set or two if you have many faucet around your place, ensure that it stays in a safe location for a fast replacement the next time you need it. Restoring your kitchen faucet by yourself will save you a great deal of money on labor cost but if you really don’t know what you are doing or if you really don’t have any kind of experience doing them or if you don’t have the appropriate plumbing tools, it is better to get an assistance from a professional plumber to avoid further ruining it.
