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.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
