Noisy hot water pipe
I have a hot water pipe that when left running for 30 to 60 seconds starts to make a noise similar to an air hammer. If the cold water is mixed with the hot, the noise stops. It is the only hot,or cold for that matter, water pipe in the house that has this condition. Any thoughts on the cause and/or remedy? Any help is appreciated!

It'd called water hammering and it is a fairly common problem. Caused by air trapped in the lines and/or pipes that are not attached securely inside the walls or flooring. Usually you only get the hammering when using certain faucets set at a certain point.

There is a simple enough anti-hammering device that should take care of the problem:

Is it only one faucet or all the hot water faucets?

It is one faucet.

I had a single handle faucet in our last house that would do that. It turned out there was a piece of plastic pipe cutting in the diversion valve from the faucet to the spray hose.

Has it always done this or is this a new development?

If in doubt check with your local codes enforcement department for what is required when doing electrical, plumbing or structural work on your house. Permits may or may not be required in your area and home owners may not be able to DIY some tasks. I have no way of knowing if you have the skills needed to complete the tasks you are asking about, when in doubt seek professional assistance.

My advice may be worth exactly what you pay me for it. :-) For the record I did not stay in a Holiday Inn Express last night.

Check the air chambers behind plumbing fixtures for water buildup. If it fills with water, you may find a noisy sound. You can buy a home water pressure testing gauge from a local hardware store to gauge the problem.
