A calorie is a measure of energy, just as a pound is a measure of weight and a mile is a measure of distance. So the amount of energy you exert in doing an activity is measured by the calories burn rate.
A water pressure regulator is a plumbing valve that reduces the water pressure coming from the main water line into the house.o determine if you need a water pressure regulator test the water pressure of the main water supply to your house. You can buy a pressure gauge for a local hardware or home improvement store.
With today's modern water delivery systems, pressure regulator valves are a necessity. In fact, most municipalities require them. The pressure on a water system is directly proportionate to the number of houses serviced. In order to maintain adequate pressure throughout the entire system, a massive amount of pressure is needed. Without some sort of regulator, the pressure would be such as to cause serious problems to plumbing and appliances. Any pressure exceeding 80 psi â pounds per square inch â can damage such appliances as water heaters, commodes, faucets, dishwashers. A high enough pressure can even cause water pipes to burst. A water pressure regulator is typically installed by a plumbing contractor and is ideally set from 45 to 60 psi. Regulators are adjustable to accommodate the needs to different homes. This procedure is fairly simple and the average homeowner can usually accomplish this himself.
