"Rapid Plumbing installed a hot water heater recently. Chris, the owner, was prompt, courteous, knowledgeable and very efficient. He is detail oriented and explained everything in an understandable manner. Within an hour, the heater was installed at a fair price. Everything was cleaned up afterwards and Chris checked later that day to see how the heater was operating. We've used Chris before and will continue to use him for all our plumbing needs. He was referred to my good friend who needs a hot water heater. Rest assured, Chris is a true professional who you can trust."

"Quick response to an emergency situation. The water heater was replaced at a reasonable price. David spent a great deal of time making sure the old tank was removed carefully even though it was difficult to drain the water because of the large amount of sediment build up. He worked very methodically and made sure the new heater was installed and working properly. Also did a very good job of cleaning up."

"Barbara graciously took a look at the leak when she came by to give us an estimate for a whole house water filter install. We called her back a week later to fix the leak. Barbara showed up on time and was up front about how she planned to fix the problem, any additional costs should the planned approach didn't work, and other alternatives. She was able to fix the leak in 30 mins and we no longer have to worry about water behind the walls."

"They were super helpful from the get-go - we had the issue with our water heater at 4PM and were frantically trying to stop the leaks and also figure out who to get to help, and they called us back the same day and worked with us to get an appointment the next morning. They came and removed the dead water heater, got the new water heater we wanted installed and working, kept in touch through all our follow up questions and checked in on us ar night. Can't recommend them enough."

"Affordable HVAC repair service. You can actually ask them to do little extras at no additional cost. After I called them for emergency repair of our AC unit, they offered a complementary cleaning for the unit. Amazing customer appreciation. Totally recommended!"

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

"Jack was a lifesaver! He was the only HVAC professional we could find to repair our central AC same day. He explained everything, checked our entire cooling system, repaired it quickly and gave us tips and suggestions for moving forward and maintaining it. Also just a super nice guy. Thank you again Jack!"

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