Frequently Asked Questions

There’s often a simpler solution to your comfort problem. Maybe you can find the answer you’re looking for in our FAQ below!

• Where can backflow happen? 

  Backflow and the subsequent cross connection can happen wherever your non-potable plumbing system meets the water lines. As such, many different types of fixtures and appliances are at risk, including:

  • Sprinklers
  • Washing machines
  • Kitchen and bathroom faucets
  • Bathtubs and showers
  • Toilets
  • And more

  For commercial properties like industrial facilities, equipment such as boilers, chemical mixing tanks and laboratory equipment are vulnerable to backflow, etc.

• What is a backflow prevention device?

  Backflow preventers stop contaminants from entering the public water supply and posing a health risk to the community. Backflow prevention is vital because it helps to ensure that the municipal water supply remains safe and free of contaminants.

• Are there different types of backflow preventers? Which one is right for my needs?

  There are several types of backflow preventers, including:

  • Reduced pressure zone (RPZ) valves
  • Double check valves
  • Pressure vacuum breaker valves

  The type of backflow preventer you need depends on your property’s plumbing system as well as the most common contaminants the plumbing is vulnerable to. Professional backflow prevention services should always help determine the most appropriate make and model for your needs.

• What is backflow RPZ testing?

  Your home may have an RPZ or Reduced Pressure Zone. The zone’s consistent pressure serves as a backflow prevention device to prevent contaminants from flowing backward. At Service Experts Heating, Air Conditioning & Plumbing, our certified testers specialize in:

  • Annual backflow RPZ testing
  • RPZ inspections
  • Backflow prevention device installation and maintenance

  Since preventing trouble is always easier than repairing it, you should try to have your RPZ valve inspected every year as recommended.

• How often do backflow preventers need to be tested and maintained?

  Backflow preventers typically need to be tested annually to ensure that they are functioning correctly, although the ultimate maintenance needs depend on the type of backflow preventer you have and its current condition.

• Can I install a backflow preventer on my own, or should I hire a professional?

  Backflow preventers are complex technical devices, meaning installation is best left to a professional with the right tools and experience. Our backflow prevention specialists will ensure that the device is installed correctly and meets all relevant regulations and standards.

• What are the costs involved in installing and maintaining a backflow prevention system?

  Costs depend on several factors. You should consider the type of backflow preventer you need and the complexity of your property’s plumbing system as well as the cost of any needed parts and labor. Give us a call at 866-397-3787 for a free quote.

• How can I tell if my backflow preventer is not working correctly?

  There are several signs that may indicate that your backflow preventer is not working correctly including:

  • Leaks
  • A large, sudden change in water pressure.
  • Unusual sounds coming from the prevention device.

  If you notice any of these signs, it is important to contact a professional backflow prevention service provider as soon as possible.

• What are the consequences of ignoring backflow prevention installation?

  Without a backflow prevention device, the backflow may contaminate your supply of potable water. This contamination could also enter the public water supply, posing a risk to the entire community. This could leave you open to health or legal consequences depending on the severity of the situation.

• Are there regulations or codes requiring backflow prevention systems in the U.S.?

  The regulations and codes that require backflow prevention systems vary by jurisdiction. In some areas, they are required by law for certain types of plumbing systems or for plumbing designed to handle specific contaminants. A professional backflow prevention service provider can help review any applicable regulations for your plumbing system.
