This is driving me crazy. We bought our house last year and have noticed pretty much from the get-go that we have very low water pressure. When you flush a toilet or run the kitchen sink or washing machine while someone is taking a shower, the shower basically comes to a trickle and when it does come back on, the pressure is lower than when you started. It's very inconvenient and annoying. Has anyone else experienced this problem and if so, what is a quick fix or any fix for that matter?
