"I recently used the EBM drain clog remover, and I’m honestly impressed with how well it worked. I had a stubborn clog in my bathroom sink that wouldn’t budge, even after trying several other products. EBM’s formula worked quickly and efficiently, within 1 hour, the water was flowing perfectly again. Overall, I’m very satisfied and will definitely keep this on hand for future clogs. Highly recommended for anyone dealing with slow drains or blockages!"

Kitchen and Bath Works Inc has been owner operated and successfully in business since 1994. Offering a consultative approach and delivering on quality, custom work, our business has been overwhelmingly driven by word of mouth referrals. From start to finish, we stand by our work and our owner is committed to being present on all jobs.

"Lou is a true craftsman...honest, knowledgeable, highly experienced and very well organized. He was patient and helpful during the design phase, when I asked so many questions and kept revising the plan. It took a few months for the cabinet order to arrive. Lou was very diligent about providing a target date and keeping me informed. On the delivery day, he came at 8AM and placed leveling blocks on the walls. The cabinets arrived and, by 10AM, Lou had already unpacked and installed the first row of wall cabinets. He works alone quietly and he is very neat and methodical. There was no music blasting, no cursing...he came in through the garage and never walked beyond my kitchen. He screens his phone calls so that he is not interrupted while he works. He is very responsive but, when he is working, he remains focused solely on that project without distraction. Lou brought in an electrician and fabricator who also did a very good job. Lou has a positive attitude. He clearly enjoys his work and he is determined to do a professional job. I am very happy with my new kitchen and I plan to hire Lou again to renovate my bathroom."

FAQs for water heater repair or service projects in Port Jefferson, 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.
