When I was a kid, our beloved black Lab, Rocky, lived in a smelly and dusty dwelling called a doghouse. He came indoors only on extremely cold nights and was never very comfortable in the house. I remember cats as being free ranging, perhaps settling into the garage or barn. But nowadays they, too, more commonly live indoors.

Add to this the menagerie of other pets available to households: birds, hamsters, snakes, mice, rabbits, ferrets, potbelly pigs and more. It should be no surprise, then, that these inhabitants add to the complexity of pollutants in a home.

 With climate scientists predicting that average annual global temperatures will continue to rise, summers are expected to last longer and become more severe.

Add to that more stringent energy efficiency standards and ever-rising electricity prices, and the HVAC/R industry is well positioned to offer businesses and homeowners heating and cooling system upgrades that will reduce energy costs.

Polluted or contaminated fluids (and) sometimes other materials) can enter drinking water piping through backflow and or back-siphonage in the water system. In other words, the water is flowing in the reverse direction to which it was intended. In most cases this reverse flow cannot be seen when it occurs.

These cross connections, whether actual or potential, can be eliminated through the use of an air gap. When an air gap is not possible or appropriate, cross connection risk can be reduced by using approved backflow prevention devices and assemblies.
