I just bought a house that was built in 1907. It has low water pressure on the cold side but normal pressure on the hot water side. I traced out the pipes and they are all copper and 3/4 inch for the branch feeders and 1/2 inch pipes going to the fixtures. The line coming into the house is 1 inch copper line and comes into the basement which is where the meter and shut off valve are located. So from what I have read online I have checked and I am trying to provide enough information to help anyone out who may know what to do next. When I turn on the cold water there is basically just a trickle but if another faucet is turned on or the toilet is filling nothing will come out. So what should I be looking for? I am also connected to city water. Thanks to all of you who can help me and I look forward to hearing back.
