however, here's the problem. the shut off valve is a gate valve which i know should only be used open or shut, not to regulate flow. if i replace it with a ball valve would that be better? are they alright to be partially open? or am i better off putting pressure reducing valves / regulators on both the hot and cold supply to the shower, so the rest of the house can keep the current pressure?
thanks again for your advice
