"Mr. Rema arrived on time Sunday morning to update my water heater. He installed an expansion tank, duct work and replacing the piping to the thermostat on the water heater. He did an excellent job and took his time. Mr. Rema also went to the local hardware store twice to pick up the material that was needed. The only reason I didn't give him an A was because he quoted me a price at the beginning and then went done on the price and then tried to go back up to the original quoted price. After talking with him he decided to keep the price at the lower amount that he quoted."

Technician was knowledgeable and efficiently performed the work. Water heater performs just fine. Cleaned up workspace and took a few mins to walk through water heater and maintenance after."

"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."

"The repair man was a Burmese guy, Joe, and he did an outstanding job changing the anode bar and removing the sediment from my water heater. This should extend the life of the tank. Joe showed up 10 minutes early and finished promptly. He worked hard and had the necessary supplies and tools. He knew what he was doing. I would glad to use Joe again in the future!"

"Service was professional and experienced. They discussed with me the work that was involved before they begin the work, and whether there was any other options I should consider. The work was completed quickly, and the water pressure was improved immediately. I wish I had known the need for the repair long ago, we had been suffering from poor water pressure for some years."

"Lal personally came out to size my hot water heater replacement project, gave me a fair quote on the spot and was flexible in scheduling the work. He and his team were on-time the day of the replacement and did a tidy job replacing all connections and the drain pan. I was very pleased with their workmanship."

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