I recently installed a new shower head (30 bucks from amazon) and afterwards started to hear a high pitch sound when I turn the water on. It started off as on and off then one day the sound got really loud and all of a sudden the water pressure dropped to about half of the force.
It's since been like that for a week now. I even switched it back to the old shower head and it's still the same half pressure.
Does anyone have an idea why this is happening? is this something I can fix myself or need a plumber?
