Replaced kitchen faucet, now in our upstairs bathroom sink only has very little water pressure

Hello Maludwick,

Clean aerator at that upstair's bathroom sink. Aerator is the filter-like attachment mounted on tip of faucet's spout

Let's see if that helped

See the image below for Aerator, Thanks.

I know it appears to have bad pressure but it is actually low volume due to debris knocked loose when you did your kitchen work. John and Milo are right on the money but it can aklso be debris caught in the mixing valve in the batrhroom if the aerator doesn't fix it.

A plumbing upgrade - such as changing a faucet - can knock loose some debris and sediment in your water supply. Then, when you turn on your bathroom sink, it's swept "upstream" into the faucet, clogging it.

Clean the aerator first as others have suggested; if that doesn't work, come back and we'll walk you through flushing the fixture itself.
