"Excellent job no leaks and an upgraded water heater at no extra charge. Greg was very informative on the process of installing the water heater as I asked a lot of questions which he had patience to answer. Took time to make sure the water heater was installed correctly. I would use his expertise again. Ray"

"While visiting my father, I found out the pilot light on the hot water heater wasn't staying lit. I found out a different company (I didn't
get the name, otherwise, I'd add a negative review on them) had come out and had apparently banged a wrench against the heater in attempt to and quot;fix it.and quot; They said if it continued to act up, it would have to be replaced and quoted $2,000!!! for the job. $2,000 to replace a hot water heater isn't just steep, it's insane. I heard that they had also been out several times at $200 per visit but didn't replace the thermocouple and instead just re-lit the pilot light each time.
I found North Valley Plumbing through Angie's list and called. I spoke with the owner who said he'd have someone come out to the house. I assumed that meant much later in the day, so when their van pulled up about 20 minutes later, I was very pleasantly surprised.
So right from the start I was impressed. But that was just the beginning of how impressive North Valley Plumbing is and how impressed I was with their service.
Robert was very professional and listened to our tale of woe. He identified the problem and got right to work. He explained what he was doing and was very courteous and friendly. He didn't have the correct size part with him and said he had to go pick up a new one and would be right back. He kept his word and was back very quickly. He charged what the part cost him.
Since I don't live in the area, I told Robert if more work is needed, I'll definitely call North Valley Plumbing again. Definitely a great shop with great people.

"Oliver arrived on time and was quick and efficient. He observed a problem from some previous work done. He recommended and repaired the problem all for the same price as for the original problem. We got the original split fitting fixed and upgraded plumbing to our shower all for the price of the service call. We are very happy with the service we received."

"recently had an excellent experience with HydroTech Plumbing. Their team was incredibly professional and efficient. From the moment they arrived, they were courteous and respectful of my home. They quickly diagnosed the issue and provided a clear, fair quote. The repair was done expertly and swiftly, with minimal disruption to my day. What impressed me the most was their attention to detail and their commitment to ensuring everything was perfectly functioning before they left! top-notch service and outstanding workmanship. ð"

FAQs for water heater repair or service projects in Cascadia, OR

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.
