"Derrick did a great job! He worked efficiently and his communication was excellent. He left the bathroom spotless, fixed the toilet issue by replacing the mechanism in the tank, and showed me what he repaired. I highly recommend Derrick and will be calling him again if I have any plumbing issues in the future! Thank you Derrick!"

"It went amazing. Paid the extra bucks for emergency service, because of our smallish waterfall, looking leak, sprouting from a bathroom pipe, enough to puddle water onto our basement/laundry room floor. Initially, spoke to Chris, who was pleasant and upfront with the per hour fees, for emergency services. He sent us Tim, who was hesitant at first, due to the location of the leak, but his experience and knowledge, enabled him to decipher the location of our leak and fix it. A quick trip to Lowes, where he promptly returned and in 90 minutes, the job was done. A week later and the valve is bone dry. Yay!!!"

"This review should probably be three separate reviews, but I think it shows my trust in Vernon using him multiple times. He came out to give me a quote on a new gas water heater and relocating it about 8 feet over in the basement. The price was reasonable and he provided me the water heater information so I could see it's reviews beforehand. While installing my water heater, my tenant called and said the AC was not working. So, after completing the install and his other stops that day, Vernon went over later that day to take a look. The repair required a new part, so a few days later he repaired the AC and I had him replace a leaking pressure valve while he was there. About a month later, a house I renovated needed some repair work on a leaky drain before settlement (he was not the initial installer). Vernon went into that crawlspace and repaired the pipe and provided the appropriate documentation so we could get to settlement in time. I had Hamilton Plumbing and HVAC do work at my home, my rental, and then my house flip. I plan to have Vernon come back to run a gas line when I install a gas fireplace and again when I do my basement bathroom."

"Great job by Jiffy. They had to pull a new water line under my townhouse slab foundation to replace the leaking poly water line. Pete Kristiansen, who is very knowledgeable and experienced, knew exactly what needed to be done. Plus it was a fair price. Highly recommend them."

FAQs for water heater repair or service projects in Maryland-line, 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.
