While you did stop the hammering by finding the source of initially oscilating valve, the true problem lies in poorly installed lines. Having worked under a great plumbers watchful eye, he always made sure we secured the lines throughout the walls. Water hammering is started by a valve opening and closing quickly, toilet, washer, dish washer, even shower valves can do this at times, but the real noise comes from the pipes banging on the studs and walls somewhere in the house. To really stop this from ever happening again you need to install a water hammer arrester. Sounds complex but it is simply a short piece of capped pipe (<1 foot) installed vertically somewhere in the system, being vertical it holds a small air pocket at the top that dampens & eliminates water hammering. You need to install one on both the hot and cold lines. With the new PEX piping this has become less of a problem as PEX seems to have a little give in it that dampens the hammering.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
