"Excellent communication from Keith; outstanding service from Roger. Professional, timely, and reasonably priced. They came in under estimate on my boiler repair and advised that a second bit of work that had previously been discussed was not going to be necessary. I will definitely use them again and highly recommend them!"

"I had a great experience with this plumber! He arrived right on time and was very professional and friendly from the start. I had a leak in the plumbing in the wall between the bathroom and the bedroom and he took the time to explain exactly was going on. He even went under the house (in the cold and dark) to inspect the issue further and took pictures so I could clearly see the problem myself. He explained the repair in a way that was easy to understand and fixed the leak quickly ad professionally. I really appreciated his honestly, communication and the quality of his work. Everything is working perfectly now! I definitely would recommend him and would happily call and refer him if I ever need a plumber's help!!"

"I called Jake on Wednesday and he said he could come on Saturday morning, and he did show up on time.  He checked two leaking spots and immediate found one leaking spot on the irrigation system was not actually a leaking, but rather a test botton that should have been set to "off", but had been set to "on" after winterlzation last fall.  So he corrected it.  And he also repaired a leaking valve.  Jake has been very professional and kind, and I would highly  recommend him for anyone who needs his help.

"I was referred to Walley's by a friend after experiencing trouble getting someone in to service my burner. When I called, I spoke to several courteous and professional staff members who went the extra mile to help me. I was concerned because the burner was running loud and we had already experienced a "puff back" on our old burner and didn't want to risk that again, and we had just started having a leak from what looked like an overflow pipe. I also mentioned that I had radiant heat in one room and needed an experienced technician that could manage the anti-freeze in the system. When I told Mandy the problem, she checked with Walley Sr. and he scheduled one of his best technicians to handle our job and got him out to us within a few days. Our technician, Alex, was polite, knowlegedable, professional and honest. He told me, as well as showed me everything he was doing, asked me to inspect the burner before putting it back together and did a very comprehensive inspection. Alex found that our leak was coming from a broken pressure valve which he had on his truck and replaced immediately. After 4 hours of Alex working at our home, we recieved a follow-up customer service call to make sure we were happy with the work Alex did and wondering if we had any questions or concerns. Wow! I was impressed! I plan to continue using Walley's and look forward to a long relationship with them."

FAQs for water heater repair or service projects in Milford, NH

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.
