"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."

"My experience with this company and the water solutions that they provided was phenomenal. Even though our home was quite a ways away from their normal service area, they were still able to send a team member, Zoe, out the next day to do a test of our well water. Zoe went through all of the different tests and thoroughly explained the results every step of the way. The next day they were able to send out a team to install the recommended water softening and filtration solutions. The guys that came out to do this work were quick, clean, and able to answer any of our questions. We could feel and taste the difference in our water immediately. We don't have to use as much soap for the dishes or for the shower as we used to thanks to all the hardness being filtered out. Our hair and skin feels much cleaner after a shower. The water not only tastes better, but we feel more at ease drinking it. My morning coffee tastes so much better and is much stronger than before (so now I can use less coffee). Ultimately, I highly recommend this company if you want to have a test done of your water quality are considering a water filtration system."

"Darren, the Salesman, was extremely knowledgeable and helpful. Very low pressure sale tactics, but laid out all of the options for you. The crew came and finished installing a new heat pump and heat exchanger in a half day and then another individual returned the next day to install a new water heater. Great communication and attention to detail every step of the way! Would highly recommend!"

"I was looking to replace my 13 year old water heater and called Excellent Plumbing to get a quote. I provided all the information to Mike and he gave me a quote over the phone. I really appreciated this because most of times contractors need to conduct a home visit. Mike was professional and answered all my questions before I agreed to the job. Afterwards, I sent pictures of the old heater and its location. Mike was right on time and got to work. It took about 4 hours. I am very pleased with my new water heater. I will be calling Excellent Plumbing for my any future plumbing jobs. I definitely recommend Excellent Plumbing for their professionalism, friendly customer service and superb work."

"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."

FAQs for water heater repair or service projects in Monrovia, 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.
