I just moved into a 3 year old townhouse that is perfect in every way except for when i take my daily shower. There is very little water pressure on the hot water side of the faucet and it makes rinsing my hair a tedious and much longer process. cleaning, soaking and even changing the shower head hasn't made a speck of difference. It's a Mohen brand, if that's any help. Same problem in my second bathroom shower, again - only on the hot water side, and only when I run the shower. Tub, kitchen sink, dishwasher all work great, pressure just disappears when I turn on the water for a hot shower.
