"Marco from R & G did an excellent job replacing the water heater at my rental property. I have called him many times for a variety of services at different locations. He is very professional, and I recommend him to anyone looking for HVAC services."

"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.

"I specified that it was a tankless water heater, yet not surprisingly I was referred to a plumber who didn't know anything about tankless heaters, resulting in a waste of a couple of days. The second person did know about them, and so far the repair is working (fingers crossed). I wish CHW would pay attention to the details in my claim."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

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