I recently replaced my water heater, and since then, the water pressure for my kitchen faucet is really, really, low. None of my other faucets seem to be affected (bathroom, shower, etc.). I can't really tell if my dishwasher is affected, but my refrigerator does not appear to be. The kitchen faucet, dishwasher, and refrigerator all run off the same set of pipes that come into the cabinet below my kitchen sink. The water heater is located a floor down almost directly below the kitchen.
My current theory is some sediment dislodged from the replacement of the water heater has blocked the faucet. Is this possible? Could this be caused by anything else?
