Backflow Testing: Why Is It Necessary?

Jun 6

backflow testingBackflow testing is a crucial step in ensuring the safety of your drinking water. Backflow occurs when water flows backward into your home or business due to a change in pressure. This can happen if there is a break in your water main, or if there is a sudden drop in pressure on the system. Backflow can introduce contaminants into your water supply and can pose a serious health risk.

Testing for backflow is the only way to ensure that your drinking water is safe from contamination. A certified backflow tester will be able to identify any potential problems with your system and recommend the best course of action to take. Testing should be conducted at least once every three years, but more frequently if there are any changes to your water system.

If you are a business owner, it is important to have your backflow prevention system tested on a regular basis. Many businesses are required by law to test their systems annually. Even if you are not required to test, it is still a good idea to do so to protect your customers and employees.

Backflow prevention testing Cochrane, AB is an important part of keeping your drinking water safe. If you have any questions about backflow testing or would like to schedule a test, please contact your local water utility or a certified backflow tester. 

Backflow Testing Solutions

Mechanical

The most common type of backflow prevention device is the mechanical type. This device uses a series of valves and check valves to prevent water from flowing backwards.

These devices are typically installed at the point where the water enters the home or business, but can also be installed in line with the piping.

Pros & Cons of Mechanical Backflow Testing

There are several different types of mechanical backflow testing solutions available on the market. Some of the pros and cons of each type are as follows:

Type 1: Pressure Vacuum Breaker (PVB)

Pros:

- PVBs are typically the most inexpensive type of mechanical backflow prevention device

- They are relatively simple devices that can be installed by a qualified plumbing contractor

- PVBs can be used in a wide range of applications, including irrigation systems, swimming pools, and spas

- PVBs are typically tested annually to ensure proper function

Cons:

- PVBs can become frozen in cold weather conditions, rendering them useless

- If a backflow event occurs, the entire PVB device will need to be replaced

- PVBs are not typically used in applications where there is a high risk of backflow contamination

Type 2: Double Check Valve Assembly (DCVA)

Pros:

- DCVAs provide a higher level of protection than PVBs and are typically used in applications where there is a high risk of backflow contamination

- DCVAs are typically tested every 3 to 5 years, depending on local code requirements

- DCVAs can be repaired if they become damaged, which reduces replacement costs

Cons:

- DCVAs are more expensive than PVBs, both initially and in terms of maintenance costs

- DCVAs are more complex devices that require a qualified plumbing contractor for installation

- If a backflow event occurs, the entire DCVA device will need to be replaced

Type 3: Reduced Pressure Zone Device (RPZD)

Pros:

- RPZDs provide the highest level of protection against backflow and are typically used in applications where there is a very high risk of backflow contamination

 

- RPZDs are typically tested every 3 to 5 years, depending on local code requirements

- RPZDs can be repaired if they become damaged, which reduces replacement costs

Cons:

- RPZDs are the most expensive type of mechanical backflow prevention device, both initially and in terms of maintenance  costs

- RPZDs are the most complex devices and require a qualified plumbing contractor for installation

- If a backflow event occurs, the entire RPZD device will need to be replaced

Based on the above information, you will need to decide which type of mechanical backflow testing solution is right for your particular application. Consider the cost, complexity, and required maintenance of each type before making a decision.

Non-Mechanical

Non-mechanical backflow prevention devices rely on a chemical reaction to prevent backflow. These devices are typically installed in line with the piping and are designed to create a barrier between the water supply and the home or business.

It is vital to have your backflow prevention device tested on a regular basis to ensure that it is working properly. Testing can be done by a certified backflow tester or by the local water utility.

Pros & Cons of Non-Mechanical Backflow Testing

Non-mechanical backflow testing has a few pros and cons. On the plus side, it is relatively easy to do and does not require special equipment. It can also be done more frequently than mechanical backflow testing.

However, non-mechanical backflow prevention testing Cochrane, AB is less accurate than mechanical backflow testing, and it cannot be used to test for all types of backflow.

If you are having your backflow device tested, it is important to follow all of the instructions provided by the tester. Backflow testing is typically done on an annual basis.
