Water Hammer Arrestor questionAsk a Plumber
I have a water line in a commercial facility above a false ceiling in an office that hammers when toilets 150′ away are flushed. This line is the end of a run feeding an outside spigot on one wall of this office. I have already installed one hammer arrestor in the line in this area, but the hammer persists. Will installing a second arrestor have any effect? If not, what other options do I have? Thanks.
