Water hammer - so many issues!
I live in a very old brownstone (over 180 years old) and have had the worst banging pipes since I moved in.
I’ve had two contractors over to fix the issue. The first replaced the valves in my radiator and my neighbors. Then he sent me a quote to replace all the valves for all the neighbors in the building. The second said I have a ton of problems because of a horizontal pipe and said the easiest fix is to cap the horizontal pipe, but that could cut heat to my neighbors apartment. He said anything else will cost many thousands.
Any ideas on whether it’s possible to have a horizontal pipe without all this racket? Sadly the pipe is in my bedroom
