"The Sila technician spent as much time as necessary to diagnose the problem with my furnace. He explained his findings every step of the way. Communication from the company regarding service visits and arrival of parts from their distributor was excellent. The cost of the repair was reasonable. Overall, I was very impressed by Sila and would definitely use them again."

"I had lost water pressure on Saturday and made a emergency call to a unknown company from google. I talked to a person immediately from Cassidy Plumbing and was told I would get a call from an employee in one hour. An employee called and would come over in 15 minutes. I was amazed at the response time. He check out my water system thoroughly and told me that I wasn't getting water in the well tank causing me to lose pressure but also I was not getting any pressure straight from the well either. It was either the water pressure tank with the pressure switch or the water pump that was causing this problem. The pressure gauge was also broken. He explained fully what needed to be done, the price for each issue and since he was not able to do anything until Monday, I was first on the list.
Cassidy Plumbing called me in the morning and told me that they would be their in one hour. They came promptly and went to the well tank first and found out the pressure switch had corroded and the well tank was also not doing it's job. The tank was about 15 years old and the switch was more than 25 years old. I was told and saw everything that needed to be replaced and the price. When replacing the valve close to the water filter housing the piping broke off and upon looking at it this was corroded too! I was able to get a discount for the water filter housing since they were working on that section of piping and it was unexpected. Afterwards they tested the water pressure to make sure all was working and that the register near the pressure switch was functioning.
My water room is the size of a closet. Inside is the water heater, water softener system (tank for salt and two tall cylinders), electrical box, telephone box, cast iron plumbing for toilet and the well tank. It was tight to say the least and they did a neat job of putting everything together and cleaning up.
I have had to replace my well pump and another time the electrical wiring to the pump and both these companies could not compare to the professionalism and services that Cassidy Plumbing and Heating."

"Outstanding professional service all around by N & J Plumbing from the moment I was contacted by Nick on a Saturday (when my water heater began leaking), who initially guided me on the phone as to the actions I needed to take to gradually stop the leak - until the replacement of my water heater on Monday by Nickâ s team."

FAQs for water heater repair or service projects in Danbury, CT

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.
