How can I restore my water pressure in the house? My hot water heater's drain faucet was leaking... paid someone to replace the facet but now my water pressure in certain part of my home is very low... one of the sink has no water pressure. I called these guys back and I'm getting don't care attitude.

Thanks in advance!!

Is there no water pressure on the hot side only or hot and cold?

Meanwhile, look for any shutoff valves that aren't open

Did you try to clean aerator on that sink with low pressure ?

I'd start by cleaning the aerators as Milo has suggested... bet that is the culprit.
