Many components in the faucet have precautions you need to follow when working with it since the parts are delicate and can incur damage when exposed. First, ensure you have the magnetic kit to place the small parts that can easily get lost when removed. Secondly, close the sink drain if open, so the parts that fall on it do not drain to block the sink pipe.

There is an aerator in the faucet that you need to cover with tape before continuing the flow restrictor removal process. Moreover, check the manufacturer’s manual to get the instructions you need to follow when working with the faucet and the related parts.

4. Locate the flow restrictor and remove it

Before removing the flow restrictor, you must locate it in the faucet. After getting it, consider removing the aerator so you can use your hands or pliers to make work easier. After removing the aerator, remove the rubber washer to loosen the space the aerator is staying so that you can pull it.

5. Locate and remove the aerator

After removing the flow restrictor, remove the aerator, and kindly follow the steps. First, check the aerator to see if there is debris that accumulates inside it and remove them. Next, check the water lines also and remove any dirt particles that are inside them.

6. Change the flow restrictor.

After checking the restrictor:

  • Remove any dirt particles with it that hinder the flow of water.
  • Therefore, replace the flow restrictor and put everything back to place for the faucet to work.
  • If the flow restrictor is still good and no dirty particles accumulate, choose to fix it back to the tap.
