"I wanted to replace my kitchen faucet but there was no need. The repair person was very upfront and honest and that saved me a lot of money. He tightened a leak and put on a water purifier. In Addition, very professional, honest, and on time for the start of work! He more dedicated to his company then most owners. Yes, I would highly recommend DLA Sewer & Drain to homeowners and businesses. Thank you!"

"The kitchen faucet was leaking and I was expecting out of town guests for the weekend. I called McDonagh & Sons Plumbing and spoke directly to Patrick. He worked me into his schedule that same day. When traffic slowed him down he called with an adjusted ETA. I appreciated that extra touch and same day service.  He fixed the sink and clearly explained the problem to me. He then corrected the cartridge in the shower where the hot and cold water was reversed by an incorrectly placed cartridge.

I was impressed with his knowledge and professional demeanor along with his partner, John. Although I couldn't fix these items myself I appreciate his explanation of each project and prompt service.

I have one more project of a non emergency matter that I will schedule to have done with Patrick in the near future. This experience was so positive that I will have McDonagh on my speed dial for future plumbing jobs.

I was given the Angie's list discount as advertised on his site. His pricing is fair and competitive.

"Excellent service.  Oscar and his crew go far and above what is necessary to fix or replace plumbing.  They are very conscientious, courteous and respectful.  They are also very considerate of your property, taking measures to insure that floors are kept clean and all debris is removed when they leave.  I will hire Rardin Plumbing and Heating again, and I highly recommend them.

FAQs for water heater repair or service projects in Plano, IL

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.
