Water Hammering?
Author: SotoFamily2020 (TX) I have an older 2 story home. My 2nd floor bathroom sink, any time I turn on the cold water faucet I hear a loud rapid hammering. Similar to the sound of an air impact. It only happens with the cold water, not the hot side. Any ideas would could be the issue?

Author: SotoFamily2020 (TX) Thanks for the quick reply. I have another question, if you don't mind. My 1st floor bath room sink, anytime I turn the cold water side, the pressure drops after 1 or 2 seconds. Nothing raddles, just pressure drops quickly. Any ideas? Or could these two issues be related?
