If you live or own a property in Pasadena, Maryland, then you might want to get your backflow tested if you haven’t already. If you value both your health and your property, backflow testing is absolutely necessary.

We are fortunate to have access to drinking water right from the faucets in our homes. However, with this convenience comes the responsibility to make sure the water coming from those faucets is clean and contaminate-free.

The best way to do this is by getting a backflow test done. By the end of this article, you will be much more knowledgeable about backflow testing in Pasadena, Maryland, and how you can schedule your test today.

What Is Backflow Testing?

Let’s start with the basics and cover what exactly backflow testing is.

A backflow test examines your plumbing system to make sure that water is flowing in only one direction and the water coming from your faucets is clean.

When there are backflow issues, clean water mixes with dirty water and becomes contaminated. This contaminated water then comes out of the faucets in your home and into your drinking glasses.

What Causes Backflow?

Two things cause backflow in your plumbing system: back-siphonage and backpressure.

Back Siphonage

Back siphonage happens when there is a drop in the water pressure, which causes the water to change direction. So, the dirty water is sucked backward and mixed with the clean drinking water, contaminating it with harmful bacteria and chemicals.

The most common instance of back siphonage in a residential home is from a garden house. When there’s a drop in pressure, it could cause a vacuum effect and suck the dirty water from the hose back to the water supply.


The second cause of backflow is backpressure. This is caused by an increase in the water pressure. The pressure from the water supply is higher than the pressure of the water source. Therefore, the dirty water is sent back to the water source.

For example, a clogged pipe can cause backpressure backflow. Since the water cannot move past the blockage, it is forced back to the source from where it came.

Is Backflow Testing Necessary?

Yes, backflow testing is absolutely necessary!

According to the CDC, 7.2 million Americans are diagnosed with a disease spread by water every year. This can be prevented if more people had backflow testing done. When a water supply is contaminated, diseases such as E.coli, Shigella, Giardia, and more could be present.

Along with dangerous diseases, you could also experience heavy metal contamination in your water if backflow is present. Many commercial spaces such as restaurants are at risk for metal contamination.

One reason for this is carbonated liquids deteriorating copper pipes and having copper contaminate the water. This is typically caused by soda fountain machines.

Another reason to get backflow testing in Pasadena, Maryland is to check for chemical contamination. Fertilizers, pesticides, and more can be present in your drinking water, especially if you live near farms, orchards, vineyards, or gardeners.

Having your backflow tested isn’t only essential for your plumbing system but for your health as well. This is the only way to ensure you’re drinking the clean water you want and deserve.

How Often Is Backflow Testing Required?

You should have your backflow tested at least once a year. While many people have a backflow preventer, they may be under the impression that they don’t need to have it checked this often. As plumbing experts, we’re here to tell you that you absolutely should!

Every five years, the system should be rebuilt and a new preventer installed to ensure you and your family are drinking clean water in your home.

Who Can Perform a Backflow Test?

In Pasadena, Maryland, you must have a certified plumber conduct a backflow test on your property. These plumbers go through training and are licensed to carry out this type of test. We do not recommend that you do a backflow test yourself.

If there is something wrong with your system, they have the resources and knowledge to fix it as quickly and effectively as possible.

How Is Backflow Testing Done?

The backflow test checks for two things. The first is if the water is contaminated. The second is the cause of the contamination.

To do this, a certified plumber will turn off the water in your home before conducting the test. They will use a backflow testing device and close the valves or gates to gauge the water movement.

As a homeowner, you don’t have to worry about doing anything. Simply let everyone in the house know that the water will be off for a little while and wait until the plumber gives you their analysis.

How Long Does Backflow Testing Take?

Surprisingly, the length of the actual test is only about 20 to 30 minutes long. It does take the plumber some more time to actually set up the test and get it ready, though.

If there are problems found with the water, then the plumber will have to spend more time identifying the problem and fixing it.

In just a few minutes, you’ll know whether or not the water your drinking water is safe or whether it’s harmful to your health. Isn’t that incredible?
