Hi I'm having issues with a sudden water pressure change in my two upstairs bathrooms of my condo. The water pressure is noticeably lower in both the sinks and showers of bathrooms A & B, though the water is hot in all areas except the shower in bathroom B, where the water is only warmish. The water from the sink in bathroom B has also been noticeably "cloudy". The water pressure and temp are normal downstairs. My attached neighbors aren't having the same issue so I don't believe it to be a water main issue. I'm not sure if this is a DIY issue or if I need to call city water, a plumber, or someone to repair my water heater. If this sounds like a familiar situation, any advice would be appreciated. Thanks!
