THe water pressure coming out of our sink has decreased. Anyone know what may cause this?

Lots of good plumbers here Marco, I'm sure you will get some good advice. I'll guess they will first tell you to clean out the aerator on the end of the faucet spout and see if that makes a difference. Mine gets clogged and this helps.

Marco, start with the aerator on the end if the faucet if that doesn't help just post back we will try to help.GOOD LUCK, AC
