"I found TriState Home Services on Angies list and contacted them. Since it wasn't an emergency I scheduled them to come out the following day. The Plumber (Chris) did a great job assessing the problem with the leaky faucet and indicated that given the age of the faucet (41 years), he could attempt to repair it but wouldn't guaranty how it would last and recommended that I replace it. I agreed with his advice especially considering the price comparison of repair vs. replace - the price was reasonable. The quality of the work top notch, on time, and as promised. I would recommend TriState Home Services and will use them in the future."

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"I hired a plumber through HomeAdvisor using prepay but I would not recommend this service. The contractor left a leaky pipe that caused water coming up through carpet. I had to purchase a wet vacuum to dry out the carpet. I had to contact HomeAdvisor again and hired Dave the Plumber, LLC who had to redo the installation done previously. Dave the Plumber replaced all the piping and outside spigot because of a water leak the previous contractor left. Thank you Dave the Plumber for being a professional and a job well done."

"Mr. O'Donnell did an excellent job replacing our water heater and removing our old one. They were on-time and arrived at the scheduled time to perform the install. He also communicated very well with us to make sure he had all of the supplies he would need for our particular application when he arrived."

"This review is solely about the installation portion of the Puronics Water Treatment System since it was just installed today. The install team arrived on time, ready to go to work. The location of my main water line was tricky to get to, but they found a great solution to tap into the line via a drop-ceiling access point. They located the Hydronex Water Conditioning Cylinder and Salt Backflush Container exactly where I wanted it. Their work was clean, tight, and very professional. The RO system was backordered, so they explained that they will return within the week to install that portion of the project. They prepped for the RO install by drilling and installing the faucet in my granite countertop. After the install, they explained the whole system to my wife and I and we were up and running with conditioned water. I can't say enough about my experience with Chuck on the initial phone call, Miles who provided the water testing and sold me the system, and Ryan who installed the system. So far, I can't envision any issues that might arise with Orbit Water Solutions since they have provided outstanding service to this point!"

"My well pump pressure tank needed service and I called Friday and Barbara was very professional and eager to help. She took the time to understand the issue and even reviewed the pictures. Barbara is very passionate about her job. She was able to schedule for Saturday. Dave came out. He called to let me know that he was on his way and let me know when he will arrive. He was very punctual, professional, friendly, and down to business. Totally impressed with the way he solved the problem and made sure that answered all of my questions. This company is very ethical and I would recommend them to anyone."

"Our plumbing system was 33 years old. Arts Plumbing completely replaced the entire water system, plumbing, water heater, water tank, some bathroom fixtures, and installed a water filtration system. We had outside hose lines installed. The crew was experienced, professional, efficient and friendly. Everything was organized, labeled well and they went over the system with us. They offered a few suggestions that really helped the efficiency of the system. It was a pleasure having them do the work, great people! We were pleased with the price and we will continue to use them for all our plumbing needs."

"We needed our water heater replaced. It was somewhat complicated because we wanted to upgrade the tank in size, but we had limited room for it. There was some back and forth in finding the appropriate tank, but the salesperson and technicians were very pleasant to work with throughout the whole process. When the pipes were moved and the tank was installed, it was done efficiently and professionally. We are very happy with our experience and the final product."

FAQs for water heater repair or service projects in Knoxville, MD

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
