"I bought a house in Ardsley recently. So, I was looking for an honest and reliable plumber whom I can trust if needed. So, I asked my realtor and she recommended Mr Wilson Taccuri. But He is a dishonest and unreliable plumber. I spoke to two other plumbers over the phone for 3 issues in one of my bathrooms. 1. low water pressure in faucet 2. leaking water around the P trap in the same sink and 3. constant dripping of water thru faucet. They recommended that I replace the faucet with a new one that would take care of everything.. Then I called Mr Wilson Taccuri and told my issues. He came home and fixed the first 2 issues and recommended replacing the faucet to fix the 3rd issues. I wanted to see what he suggest and what he does. Then, I had to buy a new faucet and call another plumber again to replace it. All issues could be fixed in one setting by changing the faucet and changing the valve as those were non-urgent. But he made me call plumber twice and increased the cost of my project."

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