Low water pressure can be a frustrating problem for San Francisco area homeowners. There are a number of causes for it, some of which can be fixed by you and some that require the assistance of a professional plumber.

A faucet aerator can get clogged and rusted over time. Unscrew your aerator and inspect all of its parts, especially the screen, for any buildup. If you are able to remove all of the buildup, simply screw the aerator back in and check your water pressure. If your aerator is rusted, it might be best to simply replace it with a new aerator.
