Commercial Backflow System Testing, Repair, and Replacement in Dallas-Fort Worth
Backflow devices are an essential part of the potable water system of any commercial plumbing building. Backflow devices are designed to prevent water from flowing backwards. For example, if there is a loss drop in water pressure in a building, the water that is inside of the building will flow backwards from the point of use towards the City meter. If the water that flowed backwards is contaminated, it will mix with the water that is downstream and possibly infect the people that drink the water. For example, when a dentist places a water hose inside of the mouth of one of their patients all of the water that is that hose is now contaminated. There must be a backflow device on that water line to prevent it from flowing backwards and possibly inuring the people that drink the water. Most municipalities require a backflow device to isolate the building and at every point where water can be contaminated.
Common points of contamination include:
- Irrigation systems. Most landscapers use chemicals to treat lawns, and irrigation runoff can carry traces of those products.
- HVAC leaks or condensation. The water that runs through your HVAC system is unsafe for human consumption, and when it leaves your system, it must be kept separate from potable water sources.
- Dental chairs and suites. Water that has already come into contact with humans is considered unclean, including the water dentists use in examinations and treatments.
- Boilers. The sediment that accumulates in boilers through regular use is considered hazardous.
- Commercial dishwashers. Dishwashers without proper backflow prevention can introduce food waste and bacteria to the water system.
- Espresso machines. These devices contain tiny boilers that are just as hazardous as their larger counterparts.
- CO2 machines. CO2 can corrode copper pipes, releasing harmful toxins that make water unsafe to drink.
