If I turn on my bathroom faucet (hot or cold) too quickly there is a muffled clunk sound and the water only drips out... if I turn it slowly the pressure is greater, but eventually it clunks and the water only drips out. My other bathroom sink is beginning to do this as well. Any ideas on what I can do to fix this and get my water pressure back to normal? Thanks!

Describe your faucet, one or two handles and how old? Sounds like a cartridge or washer is loose and the force of the water moves the washer blocking the feed. Now two baths getting the same problem at the same time doesn't sound right to me. Does anything weird happen when you flush the toilet, use the tub faucet or kitchem sink? I am wondering if there is something else common to multiple fixture that could be blocking the line.

Have you checked the aerator screens?

There's no problem with the tub faucets or the kitchen sink faucet (all one handle faucets). The two bathroom faucets were here when I bought this house so they are both at least 4 years old - both two handle faucets ("peerless" brand) - in one bathroom the cold water works good, but the hot "clunks" and goes to dripping. In the other bathroom the cold water barely comes out and the hot "clunks" and goes to dripping... THANKS for your help!
