How do I know if my water heater's gas valve is bad?

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.

Are water heater gas valves interchangeable?

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.

"Supper job, this was a difficult job. I did not know what was wrong with the toilet clog, it flooded out two floors over 7000.00. I first called Roto Rooter the fix it for two days. We were referred to Monster Plumbing and he came fixed it and told me if I had any more problems to call him again. Two later again toilet clogged. He came out with a scope and found some type of wiring that the builders dropped in during our rebuild after a fire. Pulled it out and what a relief super job!!! He was very assertive that he would find the problem. GREAT JOB!!!"

Let us turn your renovation dreams into reality request a quote today!

"We write this review as a sigh of relief now that our renovation project with River View is finally complete. The quality of the final work is excellent, and the construction crew, architect, and county inspector were all great to work with. The original crew we worked with, led by Edwin, were so hardworking, friendly, thorough, and fast. That's what really pushed us from 2 to 3 stars. However, the process getting here was frustrating and unnecessarily chaotic. Timeline & Communication Issues: Initial promise: We were clear that the renovation had to allow us to live in our home during construction and be completed before Christmas. Early communication: Our original project manager, Cris, was personable, and early communication seemed fine, if a bit informal and sometimes inappropriately personal. Major miscommunication: Near the holidays, we discovered that the plans submitted included cutting into the roof — something we explicitly said we didn’t want. This contradicted verbal assurances and caused major last-minute changes. Project Management Failures: Poor planning and oversight: Cris and the architect’s plan didn’t align with the construction work. We had to get involved directly with the county to fix errors. Paperwork errors: Incorrect submissions to the county added delays and confusion, which we had to monitor ourselves. Last-minute scramble: We were cleaning up dust on Christmas Eve due to these planning failures. Personnel Turnover & Lack of Handoff: Cris leaves the company: No proper handover to James, the new PM, who was unfamiliar with our project. Crew replaced: The original crew, who were great, were gone; new crew had no context or direction. James leaves: Another handoff with no context — the third PM had no idea about our project or its outstanding items. Escalation mishandled: When we raised our concerns with Kyle, the CEO, the response felt dismissive, with no accountability for the previous missteps. In summary, it's a beautiful end result... but we’re glad it’s over. The process left us frustrated, confused, and frankly, exhausted."

Len The Plumber, LLC. is a leading plumbing and drain company serving Central Maryland. Our certified professional plumbers are available same day to assist residential customers in Anne Arundel County, Baltimore City, Baltimore County, Carroll County, Cecil County, Harford County, and Howard County. Our knowledgeable plumbers have years of experience dealing with a wide variety of plumbing issues including plumbing repairs, drain cleaning, water heaters, well systems, heating systems, sewer, water, and gas lines. We’re open 7 days a week with no extra charge on evenings or weekends!

"On the positive side, the plumber himself (Mr. Ralte) was great. He was courteous, efficient, competent and friendly, and he cleaned everything up nicely. If I were just giving a rating for him I would give 5 stars. Unfortunately, I can't do that for the company overall. My biggest complaint is that the $591 charge for a simple 25 foot snaking of the drain seems exorbitant. I'm actually annoyed with myself now that I agreed to it, but I had already waited 3 days to be able to use my sink and it was too late afternoon for me to get anyone else out that day. In fact, they started with an estimate of $900 (not based on any detailed inspection, just on the fact that neither the sink nor the dishwasher would drain). I actually had the feeling that Mr. Ralte was a bit embarrassed about this estimate, because when I pushed back he immediately offered to try to get me a discount. He went out to his truck for a few minutes, came back and said they had agreed to come down to $591. This seemed like a very arbitrary amount, perhaps aimed at making me feel like at least it was under $600. Still, I was so sick and tired of waiting that I agreed to this, even though I regret it now. The whole visit took slightly over 1 hour, and it turned out that all he really had to do was detach the pipe from the wall, use the regular snake (not even the "super snake") for about 15 minutes, and re-attach the pipe. Then he poured a bottle of (my) bleach down the drain and it was done. Aside from the cost, my first appointment (Sunday 2-5 PM) was a no-show (I got a call 4:45 to say no one would be coming -- too late to try to find someone else). I know this happens sometimes, and (even though it had been predicted), it's not their fault that we had 7 inches of snow overnight so they couldn't come on Monday. But I had to call them on Tuesday morning to confirm that I was on their schedule (11 AM-2 PM), and then called again at 3 PM, only to be told that they hoped they could get someone there that day. After I protested about this, they finally agreed to send someone right over and Mr. Ralte showed up about 45 minutes later. I would rather not have said I would not hire them again, since I don't like to burn bridges, but the review form forces you to choose either Yes or No, and I'm really not inclined to say Yes..."
