"Called Modern Plumbing Systems (based on a NextDoor recommendation) to install a new hot water heater and sump pump and couldnâ t be more pleased. Bryan, the owner, was the consummate professional â immediately returned my phone call, checked on all available options for my specific system and needs, thoroughly explained each option to me, provided an immediate quote based on photos I sent, and then did a great job on the install of both the hot water heater and the sump pump. I would highly recommend him to anyone in the market for a new hot water heater, or any other plumbing needs for that matter. Super satisfied and would absolutely hire him again!!"

"Saved by Ehrhardt Brothers Quality Plumbing (a.k.a ColumbiaPlumber)! (West of Baltimore) Our gas water-heater failed! It’s 30° outside! (Mar 2026). It was leaking, so we shut off the gas, the pilot, and the water inlet, to lessen damage if it burst. Ehrhardt offered a price based on our descriptions and photos, of course with caveats for anything unexpected. A water-heater costs a pretty-penny, but less than we expected. A fair price. They came the next morning, and had the water heater replaced in 90min. Impressive. But the manufacturer sent a unit with a bad pilot! Ehrhardt returned immediately and in 30min, they figured it out. They had a replacement part over-nighted. The next morning, in 30min, done. Hot water. AAAAAHHH :-) The problem was the manufacturer’s fault, and Ehrhardt handled it flawlessly: Excellent communication by Ehrhardt, priority attention to our problem, no excuses, just fast resolution. Great service staff. Perfect!"

"Tess was exceptional. he replaced a leaking old water heater. When I made the call, he was on another job but since water was leaking he came later that evening to address the leakage. He was respectful and hardworking. He came on time and finished the job on time, the project was top notch. His price was very reasonable compared to others."

"Within 24 hours of my posting the need to replace my water heater the work was done - very efficient and easy!"

"This was a last second thing. Our hot water heater died on us. Left him a message on Tuesday afternoon. He showed up first thing next morning. Right on time. Discussed the job and he gave me a estimate with a small window. And he said he could have me back with hot water in a few hours. Sure enough less then 3 hours later I’m back running. Very good and clean job. Very professional with all aspects of the job which was nice. Best part of it all when it’s time to pay his his price was barely over the low end of his estimate. Everyone else would most likely been barely under the top end of their estimate. So a very good clean job done as a rush for a good price."

"I emailed Day and Night Plumber after my old water heater started shooting water out the front panel and within 10 minutes I got a phone call from them with an appointment for an estimate with Marin. The quote was very reasonable and after I supplied the Hybrid Water Heater, Marin was able to come install it on Sunday. He was extremely knowledgeable, efficient, and hard working. He finished everything, cleaned up the area, hauled away my old water heater, and showed me how everything worked. He even gave me a military discount and 12 month warranty on labor. If you need a plumber for anything, give Day and Night Plumber a call, they will give you top notch service for a reasonable price."
