What causes a few of my faucets to do have low pressure?

[CS2020]

Low pressure, and pulsating-vibrating as water comes out. It wasn’t always like this… it used to be fine. Water pressure in the house is good, approx 75psi. Thanks.

If the flow is low for both hot and cold, check the aerator screen on the spout. However that would not explain pulsating or vibrating.

Anyway, check hot and cold separately.

good chance its just the aerator
