Bathroom Sink Water Pressure

[Scottb88]

Just moved into new apartment, 2nd floor of a 3 story brownstone (3 single bedroom apartments total).
Water pressure in bathroom sink is terrible. Approx. 20% flow on both hot and cold.
Bathroom shower has good pressure and toilet fills correctly.
Pressure has no change when running hot and cold together so I assume not a valve issue, since I doubt they would both fail with the same consistency?

Kitchen (on other side of apartment) sink pressure is good, dishwasher fills correctly.

Not sure what the cause could be, there can only be so feed lines in this house...a blockage in the sink faucet?

Please help. Thanks

Make sure stop valves underneath the sink are fully open. Remove the aerator and check flow. Clean or replace if you find good flow with aerator removed.

Take out and clean the aerator. When you take it off be sure to open the valves to flush out the lines too.

Federal water use restricts the flow on vanity and kitchen sink faucets. It might be normal and your kitchen faucet may not be all that new, thus, less or no restrictions in it. Don't confuse pressure with volume. In reality, the pressure is likely essentially the same everywhere in your home (well, it does go down slightly with elevation increases), but if there's any restrictions, the volume delivered will be less.

Open the valve and measure how much water comes out then compare that to the rules. If the aerator is not partially clogged up, it might have filter screens on the inlet to the faucet, and they could be partially clogged, or it could just be normal.
