"This was my very first experience with Modern Plumbing Systems and it couldn't have gone better. I'm extremely delighted with how well the project went from start to completion. The owner, Brian, is extremely knowledgeable, capable and experienced. In addition, I found him to be totally transparent regarding all the important factors, such as cost estimates, product selection, quality and specific tasks to be performed in completing the project. All of which were provided upfront and in writing quickly and efficiently. As mentioned, while this was my first experience with Modern Plumbing Systems and it surely won't be my last. I now have a family plumber, going forward. They are honest, trustworthy, provide great customer care, efficient, provide very fair and reasonable charges and a breeze to work with."

"The plumber was a forward thinker and his solution to the problems was outstanding. I don't remember his name but he is an excellent plumber. I will call on them for all future plumbing jobs and ask for him by name (which I will know by then). Jon May, Gaithersburg, MD"

"Rema was very thorough when installing my new kitchen faucet. He came to my home at 6:15pm, which surprised me. In my experience, it’s difficult to get a plumber past 5pm! My faucet works perfectly and he was very nice. He said he has been doing plumbing for 20 years! I think I have found my “go to” plumber!"

"We had a sewer incident where we could not flush any of the toilets or even let the water out of the sink. We called the plumber that we have used for 30 years and was not able to reach them. In desperation we looked up on Angie’s List and found Ehrhardt Brothers Quality Plumbing. They had all of their crews out working and thought that they could get someone out by late evening. Later they called back and said that they could not make it that day. After begging and pleading and explaining my plight they said they would indeed come out that day. They arrive and were the most professional plumbers that I have ever seen. They made quick work of the blockage in the sewer line, cleaned up the area and were gone in short order. The cost was about half of what I expected to pay. I am thrilled that I have a new plumber."

Plumbing FAQs, answered by experts

A gurgling toilet usually doesn’t mean that your septic tank is full. If waste can’t drain into a full septic tank, you’ll see water and sewage backing up into your fixtures, but the air that causes gurgling is a result of poor venting. You are more likely to have a clog in your vent stack or a damaged air admittance valve.

If you don’t have a sewer cleanout, clearing out clogs can be extremely difficult. You would need to try to clear the clog from sink drains, but it can be harder to reach the clog all the way in the drain line. A sewer cleanout makes it much faster and easier for pros to clear clogs from your main sewer line.

Unfortunately, no, you cannot shower while your septic tank is being pumped. The water needs to be shut off while your septic tank is serviced, which includes showers, toilets, sinks, and dishwashers. Take a shower well before pumping is scheduled to begin. Once the pumping is complete, you can resume regular water use.

The water in your toilet tank refills after each flush. So if you see dirty water in the bowl, you should check the tank to see if it’s coming from there. A dirty toilet tank can be the result of sediment in the water itself—-after all, the water will sit in the tank between flushes and can cause the interior to change into a dingy color. Faulty toilet components, like an old flapper, corroded tank lever or chain, or damaged seals, can also lead to dirty water as the materials break down inside the tank. You can clean the toilet tank or change out the old parts to give it a fresh start.

Yes, you can usually replace a sink without replacing the vanity. It really depends on the type of vanity and the type of sink. You’ll need to make sure you purchase a sink that will fit in the existing space. This requires precise measurements. You’ll also have to carefully remove your old sink, making sure you don’t damage the countertop during the replacement.
