Water hammer on cold and hot water pipes
I remodeled the bathroom and replaced all fixtures with new materials. Once I was done I have water hammer in my pipes, which I never had before. The water hammer occurs on the cold and hot water sides and occurs with every fixture on that floor (toilet, sink, and shower in two bathrooms). I have air chambers on all fixtures and have drained the system to replenish the air supply. I also added air hammer arrestors to every fixture except the shower because it can only be accessed by cutting a whole in the wall. The pipes are not accessible unless cutting sheetrock. Please help!
