I live in SE Michigan, where we have had a long dry spell recently, complete with water usage restrictions, etc. The water flow in my kitchen and bathroom had been low, and someone suggested cleaning the aerator screens, which worked well. They got full of grit again, and I cleaned them again, successfully. This time the kitchen water flow is low, but there is no grit. In fact, when I take the whole aerator end off, the flow is still too low. I don’t know what else to do! Anybody have any thoughts?
