"Was pleasantly surprised by their timely response to provide an estimate, and then started work immediately following. I discovered my water heater leaking around 2 and by 7:30 they were done and gone. Really nice guys too. Would definitely use again and have no problem recommending them."

"Robert arrived promptly when he said he would, and replaced a faulty shut-off valve. He then noticed a slow leak at a connection my utility company installed, and repaired that as well. All for the price he originally quoted me. I would recommend Robert's Plumbing Service without reservation. From now on, he's the go-to guy for all my plumbing needs."

"He installed a furnace, central air unit and duct work. I previously had oil with hot water baseboard heat. He did a great job and has a great price. I know the job was big but most places were quoting around or over $13,000, and he was cheaper. He was always on time, courteous, cleaned up after himself every day and did the job within a few days. I would highly recommend him!"

"Very prompt. We blew our hot water heater overnight. I found "A" Real Plumber with Home Advisor. He was at the house at noon and done by 1:30 as he said he would. Replaced the hot water heater at a very reasonable price and removed the old one. Great personality and a pleasure to be around. Winston and his son Justin are now our go to Plumbers. Thanks Winston and Justin."

FAQs for water heater repair or service projects in Guilderland, NY

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.
