Faucet Aerator

An aerator is flow rate controlling device and usually located near tip of faucet. Usually, minerals particles or debris may clog the aerator as a result water pressure drops.  In most cases cleaning it may help to restore water pressure.

First all remove the inflate and dip it into the vinegar and left for overnight. If you are in hurry then 5-10 minutes can also be helpful. But if the aerator too much clogged and cannot be cleaned by using vinegar then you can replace it, they are cheap.

Faucet cartridge:

Tap cartridge can also be clogged by mineral or tiny particles. Which also causes low water pressure. Cartridge controls the water flow. It means that when open the handle, it opens the valve and allows the water to flow. Cleaning cartridge is more complicated then cleaning aerator.

Before starting to remove the faucet, please close the shut-off valve and let all the water run out. This is to ensure that there is no residual water in the pipeline. Then, close the plug of the sink to prevent dust and waste particle from escaping into the drainage system. Now, use a flat-blade screwdriver to pry off the handle cover. After removing the handle, you can use a pair of anti-skid pliers to remove the fixing nut. Sticking the tape to the teeth of the pliers helps increase grip. In addition, this will prevent the faucet from being scratched. Then, use a pair of ordinary pliers to pull out the retaining clip. Finally, you will be able to pull the cartridge out of the opening.

You can clean the cartridge by soaking the cartridge in vinegar overnight. Use a stiff brush to scrape off the sediment. However, if you feel that the sediment is too stubborn to fall off, you should consider replacing it.
