What should I do if the tap water is small?

At the top of the faucet, there is a little thing called "bubbler". The inside of the foaming device is a multi-layer network structure, which is easily blocked by sediment and scale. You can remove the faucet, take out the filter screen and check for impurities. If yes, clean it and put it back on the screen. Or the taps at home are all small water, so you can only find a property or install a booster pump at the outlet of the water meter at home, and the problem will be solved after the water pressure is restored.
