After reading many posts on here it looks like I have the symptoms of reverse water hammer. It is in my upstairs bathroom just after a long run of plumbing. It typically happens first thing in the morning when I turn on the cold water. It flows for a second or two then I get a bang-bang-bang and the water stops. If I flush the toilet first this doesn't seem to happen. My question is, will installing a engineered hammer arrestor stop the hammer or is it possible to be a number if things that all combine to create the problem? Recently I had my 1/2" water main upgraded to 3/4" and I probably have more water pressure than I used to. Would I possible need something to reduce the water pressure and a hammer arrestor?
