Plumbing in the Home/knocking sound from pipes

I have the same tank with an expansion tank, no circulating pump and the temp is at 115 degrees. We are getting knocking also. Can the expansion tank cause any of this?

I can answer most questions when it comes to plumbing and what types of items can be purchased at the wholesale level. I can't answer too many questions when it comes to plumbing outside the home like well pumps, sprinklers, etc. I also have a lot of experience in plumbing fixture trends, what is available, getting the most value for you buck, what manufacturers to stay away from, and who are the best to deal with. If you don't know if something is available, if I don't know, I can find out within a day. I will even field questions about items you have seen at "big box" stores, and I can give you my opinion on them.
