: I recently bought a 1930's house. It has a plumbing system which is a combination of cast iron and galvanised metal and copper. Whenever any water load is active the flow to all other loads reduces to next to nothing. I want to know if the problem is service to the house or the system inside the house. How do I determine this and if it is service to the house how do I get it fixed?
Terry: Install a pressure gauge as close as possible to the point where the water service enters your house. Watch the pressure while someone else runs enough water to cause your problem. If the pressure stays up (it may drop slightly) the problem is in your house. If it drops significantly, it's in the service off the street. If you're really unlucky, it's both, but with the exiting combination of piping materials in your Depression-era house, I'll bet it's inside. I hope I'm wrong. Good luck. Tony
