Texas Plumbing Regulations: Texas has adopted two sets of plumbing codes that must be followed by home and business owners: the International Plumbing Code (ICC) and the Uniform Plumbing Code (UPC). In Texas, for example, dishwashers must feature a "air gap" to prevent filthy water from flowing back into the machine. This means that if a dishwasher is located on a separate floor from the rest of the house or building, there should be a room with no connection to the other rooms with a door that can be closed to create an air-tight seal.
The need for an air gap is based on health concerns over bacteria growth in old pipes. If there is even a small chance that contaminated water may be returned to the tank, then a filter/air gap is needed. The only time an air gap is not necessary is when the piping system is new, there are no occupants below, and the dishwasher is expected to be used only for washing dishes and not for spraying jets of water at high pressures like those found in a dishwasher designed to clean pots and pans.
In addition to being required by law in Texas, having an air gap also saves on your electric bill. This is because dishwashers use a lot of power cooking food that was recently washed in another room. Having an air gap prevents this heated air from being re-circulated which would otherwise cause a large percentage of your electricity bill.
The original Texas Clean Air Act ("TCAA") was adopted in 1965 with the goal of protecting state air resources as well as the people's health, general welfare, and physical property. These regulations were subsequently handed to the Texas Air Control Board. The TCAA requires major sources of air pollution to obtain permits by establishing emission limitations for hazardous pollutants such as sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM10). It also provides for regulation of other air contaminants including carbon monoxide (CO) and volatile organic compounds (VOCs). In addition, the act mandates training for all air quality inspectors and reviews requirements for anti-pollution technology for new power plants.
The TCAA has been updated several times since its adoption to address emerging air quality issues as well as improve regulatory efficiency. For example, amendments have been made to increase the stringency of emissions limits for certain pollutants such as NOx from industrial facilities and SO2 from electrical generating units. Other amendments have been made to reduce the compliance time for large sources of air pollution.
This law directed the Texas Commission on Environmental Quality (TCEQ) to develop a plan for reducing ozone nonattainment areas within Texas by 2015.
It's known as a "air gap." Its purpose is to keep unclean and polluted water from backing up into the water supply via the dishwasher. It's mandated by regulation in California, but some individuals get around it by installing something called a "High Loop" under their sink. These are metal boxes that hold plastic bags inside the box to catch dripping water. The water drips through the holes in the bottom of the box and into the bag which can then be taken to a recycling center once a week.
In order for a dishwasher to be considered compliant with California regulations, it must be at least 10 years old. Older models may have a design flaw where dirty dishes can back up into the pump area, so make sure you check your owner's manual for recommendations on how to prevent this problem.
Also made of metal is the vent pipe that leads away from the dishwasher. This should be located outside your home and connected to the roof using a 90-degree elbow. It should be no less than 2 inches in diameter if made of steel or baked enamel coated stainless steel. Other types of material could be used instead. Dishwashers are very efficient at cleaning dishes, but they're not perfect and small particles of food can end up in the pump area or drain hose. These items will cause bacteria to grow if they come in contact with water, so make sure you take all of your dishes out before loading them into your dishwasher.
To prevent contamination, most plumbing rules demand an air gap on the RO drain line. Because RO systems must distribute water through their own faucet, many people choose an air gap faucet that includes the air gap into the faucet's body. This keeps water from reaching the handle or sprayer and causing it to malfunction.
An air gap is just what it sounds like: There's a hole between the hot/cold water supply lines and the faucet body. This prevents any kind of physical contact with the water supply, which would cause bacteria to grow if it reached the faucet body. It also helps prevent any kind of mechanical interference, such as turning off the cold water when you're done using the hot. This could cause hot and cold water to mix inside the faucet body, resulting in uncomfortable temperatures or even scalding.
The rule for an air gap on a RO system is required by law in some cities. In other cities, it's recommended but not mandatory. If you plan to sell your home soon after installing a RO system, then you should consider having the air gap removed because it will likely affect the value of the house.
The air gap can be filled with putty to make repairs or maintenance easier. Otherwise, you'll have to disassemble part of the faucet body to get at them.
Texas may straddle many time zones. But Colorado is almost exactly one hour behind the Lone Star State - which means when it's 5am in Texas, it's 6am in Colorado and vice versa.
The time difference between Texas and Colorado is equal to that of London, England. So if you're an American in London, you'll be an hour late for work. The same goes for anyone else in the world who lives anywhere other than Texas or Colorado.
Although they share a border with Mexico, these two states have very different lifestyles and cultures. Texans like their football and barbecue, while Coloradans love their mountains and ice cream. If you're from Texas, you might not understand why people would want to live in a state with fewer cows and more mountains. If you're from Colorado, you might not understand why people would want to live in a state with less freedom and more government regulation.
In addition to being separated by geography, Texas and Colorado also have something common: They are both part of the Western United States. The three most westerly states on America's mainland (Washington, Oregon, and California) lie within 100 miles of each other.
