"Two old shower pulls were hard to work and one leaking profusely. Also, water heater not making lots of hot water and 12 years old. Asked for a flush and recommendation for replacement. Tech showed up on time and ready to work. Rebuilt pulls quickly and knowledgeably. Attempted to flush water heater but too far gone. Showed me work done and patiently listened to and answered all my questions concerning replacement options. Gave me a good deal on new water heater and was available and ready to install same day. Completed the installation cleanly and efficiently. Couldn’t be happier with the experience. Tech (I’m sorry, I don’t remember his name) was professional and courteous and worked efficiently. Prices are fair and their use of a standardized pricing guide eliminated any feeling that they were pricing on the fly. Two thumbs up."

"We had a mystery leak, and Pop Leland Plumbing came out right away! Joel was amazing and very knowledgeable and a great representative for this company. Their service was fast, reliable, and professional and very honest from start to finish. The owner, Charles, is always an absolute pleasure to work with. You can tell he truly cares about his customers and takes pride in the work his team does. We have referred Leland Plumbing to many of our close friends and customers, and we wouldn’t recommend anyone else in the Pinellas County area. If you’re looking for a trustworthy, dependable plumbing company, Pop Leland Plumbing LLC is the one to call! Highly recommend! ❤️"

"I had a fantastic experience with Three Guys. From start to finish, the entire team was courteous, knowledgeable, and efficient. They got my Trane unit up and running in no time, and everyone I interacted with both in the office and on-site was professional and a pleasure to work with. I highly recommend them for their excellent service and customer care."

"completed the request for a plumber. Had a telephone response from owner, David within 5-10 minutes. Explained what we wanted, which was removal of an old Hot Water Heater and replacement with a new water heater. An appointment was scheduled for the next day at 11:30am. David called next day, Sunday morning, to confirm the appointment and stated he would be able to come earlier. Upon his arrival, he assessed the issue and recommended the brand, the size and provided an immediate estimate. David was more reasonable than any of the other five companies contacted, including Lowe's and Home Depot! This owner was courteous, knowledgeable and very professional. My husband is tougher on professionals than anyone out there. But, David won him over! You will not be disappointed with Day or Night Plumbing. We would definitely use David for any plumbing needs. We have used the professionals from Home Advisor several times and have not been disappointed to date. Good job David!"

FAQs for water heater repair or service projects in Largo, FL

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.
