If your faucet emits less water than it should, your ventilator may only need to be cleaned. The hard water sediment and sediment in the water gather on the filter screen and gradually block the filter screen. Cleaning the aerator is easy and takes less than 5 minutes. Here's how to do this:

 

 

 

1. 1.Turn off the tap.
2. 2.Wrap the aerator with a rag to protect it, then clamp it with pliers and rotate counterclockwise to release it. Once it rotates freely, loosen it and remove it with your fingers. (Note: the thread of the aerator is a standard thread, which can be loosened by turning it counterclockwise. However, since you observe it from above the faucet (the opposite side of the connection), you actually turn the pliers clockwise.)
3. Turn the aerator upside down, put it under the faucet and turn on the faucet. This will flush the screen and remove sediment from the screen.
4. Remove rubber washer and place it in a safe place. Place the rest of the aerator in a bowl of white vinegar overnight. Vinegar will dissolve hard water deposits that will not fall off due to backwashing.
5. Put the washer back on the aerator and screw the aerator back to the faucet. Wall Mount Chrome Bath Faucet Tighten the threads with a rag and pliers to prevent water from leaking from the top of the aerator when opening water. If water leaks, tighten the aerator a little more.

Select a new or replacement aerator

If your ventilator is damaged, or you need to install a ventilator on a faucet without a ventilator, you need to measure your faucet to make sure you get a suitable ventilator. Pull-Down ABS Sprayer Kitchen Faucet Aerators are available in standard English and metric sizes. The surest way to find a match is to take the old inflator to the store and buy the same one. If you don't have an old aerator, try the following techniques:

 

Put a quarter, a nickel and a dime under the tap. Select the coin that best matches the opening, and then select a ventilator of the same size. What matches a quarter coin is an ordinary size ventilator, Water Mixer Tap Basin Faucet what matches a fifth coin is a primary ventilator, and what matches a dime is called a "Tom Thumb" ventilator.

If your faucet doesn't match any of these coins, it may be metric. Use a ruler or tape measure to measure the diameter of the faucet opening, and then buy a ventilator with that diameter.
