The Importance of Backflow Testing

Plumbing is the system of pipes that delivers drinking water, removes waste, and transports rainwater. It is important to note that plumbing is distinct from piping systems used for industrial purposes.Backflow Testing

One of the most common plumbing issues is a leaky pipe. Leaking pipes can cause significant damage if left unchecked. Thankfully, there are a few things you can do to detect a leaky pipe. Visit to learn more.

The plumbing system in your home or business brings water into the building and removes waste. It also heats and cools the water supply, if necessary. The plumbing system uses gravity and pressure to function. The plumbing system can include pipes, valves, tanks, and fixtures. There are two main types of plumbing systems: one pipe and two pipe systems. In a one pipe system, all of the hot and cold water supplies run through the same pipes. This type of system can cause problems with the temperature and pressure of the water, which may not be as consistent as you would like.

The other type of plumbing system is a two pipe system, which carries freshwater and wastewater through separate pipes. It is important to have a two pipe system in place because it will prevent the freshwater from mixing with the wastewater and causing issues with your drains and sewer system. This type of system is also more expensive than a one pipe system because it requires the installation of additional pipes and fixtures.

Piping is a term that is used in many different fields, including plumbing and industrial process piping. It is the network of pipes used in industrial processes to transport chemicals, water, oil, gas, and other liquids between equipment. Piping is essential for industrial processes, such as food processing, chemical manufacturing, oil and gas refining, and power generation. The design and construction of piping systems requires careful attention to detail, since the pipes must be able to handle high levels of pressure, extreme temperatures, and corrosive materials.

The materials that are used for piping systems depend on the needs of the application. For example, a corrosive environment requires pipes that are made of corrosion-resistant materials such as titanium or stainless steel. Other common piping materials include plastic, copper, and galvanized iron. For industrial applications, piping can be designed from wood, fiberglass, glass, aluminum, and steel. In addition to the pipes, piping systems also include sensors and automatic control devices that are used for monitoring and controlling fluid flow rate, temperature, pressure, and other variables.

Backflow Testing

Backflow testing is an important part of your plumbing inspection. It ensures that your water system is protected against dirty, contaminated water making its way back into the clean water supply. This test is a simple way to check the effectiveness of your backflow prevention devices. It’s also a vital part of meeting any building, fire or plumbing codes in your area. Here are a few reasons why you should make backflow testing a regular part of your maintenance routine.

The primary reason to have your backflow tested is to keep your family healthy. When water moves backward into a household, it can come in contact with contaminants such as human waste and chemicals. These can then pollute the household’s drinking water, posing serious health concerns for the family. In a worst-case scenario, the contaminated water could even make its way back into the public water system and spread disease to neighbors and other households.

When your backflow test results in a failed inspection, it’s important to repair or replace the device as soon as possible. Failure to do so can lead to severe damage to your pipes, plumbing fixtures, and even the areas surrounding them. This can be expensive, especially if the resulting water damage is extensive.

Another reason to get your backflow tested is to protect your property. Backflow is a big problem for homes and buildings, as it can cause significant damage to structures. When water travels backward into a home, it can hit walls and corrode them over time. It can also clog pipes and make the house smell unpleasant. A backflow preventer can help prevent this from happening by ensuring that the water only flows in one direction.

Backflow testing is required for apartments, condos, restaurants and other commercial properties as well as many single-family homes. It’s important to hire a professional for backflow testing, as they will be familiar with proper testing methods and will abide by the local code requirements. You can verify that your backflow tester is certified by contacting the local government office. They should be able to provide you with the backflow inspector’s certification number.


Cross-connections between plumbing and piping can cause backflow which could introduce contaminants into the potable water supply. These contaminants can include biological, chemical and physical substances. Unprotected backflow can cause contamination of your own drinking water as well as the public water system resulting in health problems for you, your family or customers at your business. In order to prevent this a Backflow Prevention Device or backflow test is required.

Backflow prevention devices are specialized products that create a strong pressure system in your plumbing to force your water to continue moving forward and not to reverse flow. These devices are installed at critical points in your plumbing system where a backflow hazard is most likely to occur. These devices are also tagged with the date of installation and tested by a certified backflow technician (Backflow Tester) on a regular basis.

Successfully controlling backflow depends on a series of actions, starting with the development of a backflow control program that sets guidelines for water safety. These guidelines should be reviewed and agreed upon with key stakeholders including plumbing services firms, your water purveyor and your town officials. This program should then be implemented by performing regular inspections, testing of all contaminant backflow prevention assemblies and enforcing related codes.

One example of a backflow situation in a residential home occurs when a garden hose is attached to the service sink and the end of the hose is submerged in a tub full of soapy water, detergent or fertilizer. The hose could backflow through the service sink and into the kitchen faucet, causing the contaminated water to come into contact with your clean drinking water.

MWRD’s Backflow Prevention Program is designed to eliminate these dangerous situations. The program is designed to be a comprehensive, cost effective and easy to manage approach to protecting the public’s health. The program provides for the inspection, testing and education of all customer types, including residential customers. In order to provide the best possible backflow protection, the program allows for a variety of devices and methods of protection that are approved by MassDEP and the Massachusetts Plumbing Board.

Schedule a Test

If it’s time for your backflow test, contact us to schedule an appointment. The testing process can take a few hours, depending on your plumbing system and the number of tests needed to pass.

Once we’ve completed your backflow test, we’ll return on a different day to tag the device with a label that shows you and authorities when it was tested. This is an additional way to keep track of your backflow device’s maintenance and helps you avoid significant water leaks and related damage down the line.

For some backflow tests, a plumber will need to remove one of your downstairs toilets and install an inflatable ball in the drainpipe. This will block all the water in your home for about an hour, allowing them to measure its level at the removed toilet over the course of the test. If the water levels drop at any point, there are likely backflow problems in your system. If the water level remains consistent, the backflow prevention device is working properly. Schedule a backflow testing appointment today to make sure your home’s plumbing is safe.
