Reliable Backflow Prevention in Honolulu

Keeping Your Water Supply Safe from Contaminants

The purpose of backflow prevention devices is to ensure that there is no water flowing in an undesired direction. Normally, water is supposed to move from the distribution system to your building and out. When there are issues with your backflow system, possibly from poor water pressure, you risk contaminating your drinking water.

Having a trusted and established Honolulu plumber treat your backflow prevention devices, you can ensure that you are not drinking unsafe water. At Pipe Masters, we have the experience and skill set to effectively treat and maintain your backflow prevention devices. Make sure to check out our drain cleaning services as well!

The Importance of Backflow Preventers

Backflow preventers are important to help keep out pollutants from your water supply and make the water itself taste clean.

Here are some reasons backflow prevention plumbing systems are important.

  • Safeguarding Water Quality: Backflow preventers play a crucial role in effectively keeping out pollutants, contaminants, and unwanted substances, ensuring that the water you consume tastes clean and is free from harmful elements.

  • Ensuring Safety: By effectively blocking the entry of contaminants into your water system, backflow preventers help minimize the risk of waterborne illnesses and protect your health.

  • Enhancing Plumbing System Functionality: Backflow preventers are essential features of a home's plumbing and water system. These devices help maintain proper water pressure and prevent potential damage or disruption to the plumbing infrastructure.

  • Compliance with Regulations: Complying with these regulations not only ensures the safety of your household but also demonstrates your commitment to responsible water management and adherence to local health and safety standards.

  • Expert Inspection & Maintenance: Our team of expert plumbers in Honolulu offers comprehensive inspections and maintenance services to ensure that your system is functioning optimally and providing the highest level of protection for your water supply.

Types of Backflow Prevention Devices

Backflow prevention devices help safeguard against backflow and prevent contaminates from entering your water supply. Our professional plumber will ensure that the right type of backflow device is installed for you and your home to receive clean water. Below we have 3 different backflow prevention devices that we can help with.

  • Reduced Pressure Zone Device: The RPZD preventer is the best for making sure that high-hazard water contamination is contained. This sort of backflow can cause severe harm to people.
  • Air Gap: The air gap device is the most popular and most common backflow preventer. Our plumbers mostly install these air gaps in residential sinks and bathrooms.
  • Dual Check Valves : Dual check valves mostly apply to residential homes and can help deter backflow from other cross-connections.

What are the Causes of Plumbing Backflow?

If the pressure in your building is greater than the pressure in the distribution system, you could have a persistent backflow problem. No matter the potential cause of backflow into your plumbing system, we can make sure your backflow prevention device is properly installed and functioning the way it should.

  • Reduced or Poor Water Pressure: A common cause of plumbing backflow is water pressure being reduced. If your wastewater system pressure or freshwater system drops, it could cause waste material to be forced back up into the freshwater pipes.
  • Water Main Break : If your water main breaks or a large amount of water is used for firefighters needing to put out a fire, this can cause a pressure drop and cause your wastewater to suction up into your drinking water system. This is called a back siphonage.
