Do I Need Backflow Testing?

There are different types of backflow devices, but they all work to maintain the proper pressure within plumbing systems. The primary function of backflow device testing is to make sure water from unwanted sources doesn’t flow back into the drinking water supply.

Sources such as boilers, irrigation systems, and fire-suppression systems can cause backflow into your drinking water. Not only could this contaminate your water, but it could also damage your pipes and appliances.

What Is Backflow in Water Systems?

You can imagine backflow as your drinking water system having acid-reflux. In a properly functioning water-supply infrastructure, the water is kept under appropriate pressure. This pressure prevents sewage water from flowing backward into your drinking water supply.

In some cases, the water pressure may decrease because of frozen pipes, higher demand on the water system, or central water bursts. In this case, backflow and contamination might result.

For this reason, it’s a good idea to test your backflow device regularly. There are over 10,000 cases of backflow device failure each year. Some of these can cause health problems and even death in severe cases.

Backflow Testing Regulations in Maryland

Did you know that most new and remodeled homes need backflow devices? Furthermore, these devices need to be tested annually according to the Silver Spring county regulations. This test typically takes one hour. During that time, our plumbers employ their specialized expertise to ensure everything is functioning well.

Aside from annual inspections, you may want to get backflow device testing done earlier if you notice warning signs.

Here are some telltale signs that you could have a backflow device problem:

  • Your drinking water tastes “off.”
  • There is a sulfuric smell coming from the drain.
  • The water is discolored.
  • The water appears rusty or dirty.

If you notice any of these signs, call Prime Plumbing MD right away. Our experts will get to the root of the issue and fix your backflow device or other plumbing problem.

    It's taken me a while to write a review with two young kids- but i wanted to make sure i shared what a wonderful experience we had using Prime Plumbing. We had a sewer line back up in our basement (yuck) and i had multiple plumbers come out and give quotes on digging up and replacing our old copper sewer line with pvc. Tim impressed me from day 1 and stood out amongst the others with his confidence and expertise in what our options were, what to expect from the whole process, etc. They dug up our lawn (8 ft deep, approx 40 ft long) and i am so happy with how they managed to put it all back together. I can't take a current picture of it now because our yard is covered with snow, but 2 months later you'd hardly be able to tell we had a trench dug up. We were quoted around the same price by another company who said they would need to tear out our retaining brick wall and also said they'd leave piles of dirt, and that the grass seed/hay would cost extra!! Also, Prime managed to get this all done in 1 day. Not to mention, we got to keep our beautiful maple tree! This is the only tree in our yard and our kids love swinging on it so while i was ready to give it up if need be, i was going to be a little devastated. Only a few days after my initial consultation with Tim, we had a brand new sewer line! We are so happy we found a good, reliable & trustworthy company to make us feel better about forking over a pretty penny on a hidden (but very crucial) repair. Thank you Prime Plumbing!

    Great work! Very nice service; fixed our water heater issue and had us back up and running in no time. The service provided by Ernie and Hayleigh was very professional and courteous.

    [UPDATE: RESOLVED] I'm updating this review to reflect that Prime Plumbing has owned up to the situation and made it right. Once my new toilet arrived, they returned and completed the installation at no additional cost to me. The 5-stars are for Ernie and Hailey who handled the final install, and they were a complete 180 from my previous experience. They were awesome, professional, and sociable. You could tell they actually enjoy their work and take pride in it. They got the job done right. While the road to get here was frustrating, I appreciate the company standing by their work and sending the right team to finish the job. [OLD REVIEW] I hired Prime Plumbing to fix a toilet leak, and after 4 visits and hundreds of dollars, I had to do their work for them. Here is the timeline of negligence: March 27, 2025 (Invoice #90891): I paid an $89 trip fee to have a technician come out. He did a visual glance without even lifting the toilet and told me "nothing was wrong." The leak continued. Nov 1, 2025 (Invoice #97073): I paid $634.56 for a "Toilet Pull and Reset" (Service Code TUR-110). The invoice states they would "prepare the mounting system." They claimed the issue was a decayed wax seal (after initially guessing "condensation"). They did not inspect the toilet for cracks, but they didn't miss the opportunity to try and upsell me a new water heater. The leak continued. Nov 24, 2025 (Return Call): When they came back, the technician tried to blame "condensation" again and claimed "these electric toilets aren't reliable", again making excuses. He replaced the wax seal again without inspecting the toilet. Nov 30, 2025: The leak returned. Before booking them again, I spent 1.5 hours doing what they should've done. I replicated the leak and reached behind the toilet to feel the failure point. I felt the wax ring and—crucially—I felt plastic obstructing the seal. Dec 1, 2025 (Invoice #97936 Return Call): The tech arrived, and I told him what I found. He told me, "That's impossible... Show me how you did it. Show me this magic." I had to literally get on the floor and prove it to him. I ABSOLUTELY should not have had to do his job for him. He then complained about how he "can't keep coming out here" and is "losing money." Completely unprofessional. He finally pulls the toilet up, actually inspects it, and finds a crack. He sounded gleeful showing it to me, acting like this vindicated his misdiagnosis. He then told me I need to pay a third time to have a new toilet installed. THE REALITY: Did he inspect it the first time? If he did and saw no crack, then he caused the crack by mishandling the toilet. Did he not inspect it? Then the crack was there the whole time, and due to his incompetence, he misdiagnosed the issue for months while taking my money. I paid premium pricing for a professional diagnosis and fix. Instead, I got laziness in March, incompetence in November, disrespect in December, and an issue that wasn't fixed. Now they want more money to fix the issue they likely caused. Avoid this company unless you want to do the plumbing yourself after paying the bill. When my new toilet arrives, I will be reaching out to them to complete the install of the toilet at no additional cost to myself (I am not asking for a refund on the cost of a toilet, just want them to install it properly.) Otherwise, this is definitely going to be a complaint to the MHIC.

    Ernie and Hailey are absolute legends! I cannot say enough good things about Ernie and Hailey! I hired them to install a new toilet, and they turned what is usually a mundane maintenance appointment into a genuinely great experience. From the moment they arrived, the service was top-tier. They were incredibly professional and got the installation done flawlessly, but what really stood out was their attitude. They were sociable, friendly, and you could tell they actually have fun on the job. They have a great dynamic and brought such positive energy into my home while working. It is rare to find a team that combines expert workmanship with such a great "vibe." If you need plumbing work done and want it done right by good people, ask for Ernie and Hailey. 10/10 would recommend!
