"Spoke with owner Ross about replacing two water heaters. One was showing wet stains bottom. So I decided to replace both, since they were both about 12 yrs old. I decided to replace my Bradform Whites with a more high tech water heater. I picked Lowe's AO Signature 500, which is their top electric heater. Has leak detection shut off, higher heating element, vacation mode, wifi enabled etc. Labor estimate about $1400 to replace both, and I had the water heaters onsite for install. Can't say enough how Professional his plumbing crew is. Jack and Chris did an outstanding job. They kept me informed throughout the process, and kept my home clean at all times. The install projects came out great and price as agreed. Other plumbing estimates were higher, especially comparing it to those Big Box stores. Will certainly be doing with Ross again in the future. FYI, look for a company that is willing to be open to use other brand name water heaters and not just what they trying to sell you. "

FAQs for water heater repair or service projects in Lake Oswego, 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.
