WATER HAMMER ARRESTER VS. expansion tank
Can I remove the WATER HAMMER ARRESTER on my hot water heater and replace it with a water expansion tank or do I need both. I still have water hammer (pipes rattle) with the WATER HAMMER ARRESTER installed so I thought that a water exoansion tank would solve the problem. Is that correct. Thank you.

I don't have any idea why you have a water hammer arrester on you water heater, an expansion tank is what is SUPPOSED to be there to allow the expansion of heated water a place to go.
Hammer arresters are usually used near a quick opening or closing valve, like a wash machine or a irrigation system, they are also used on the top of risers
Water hammer can also be caused by pipe that isn't fastened securly, the arresters would not do anything for that.

I'm guessing because I don't know why the arrestor was on the water heater in the first place, you should be able to remove it. If you install a expansion tank it should be installed on the cold side and the air pressure should match your incomming water pressure BEFORE the tank is installed.

I install it? Correct?
