Funny timing—just swapped out my 16-year-old tank last month. No leaks, but it started making this low grumbling noise every time the burner kicked on. I debated just flushing it again, but after reading about how hidden corrosion can be, I figured better safe than sorry. I do wonder if I jumped the gun, though... part of me hates tossing something that’s still “working.” Anyone else get that weird guilt? I went with a standard tank again—hybrids seemed overkill for just two of us.
I get that guilt too, but honestly, 16 years is a solid run for a water heater. That grumbling noise is usually a sign something’s brewing inside—probably sediment or worse. I’d rather swap it early than risk a flooded basement. You made the right call.
Yeah, 16 years is pretty impressive for a water heater—most folks start seeing issues closer to the 10-12 year mark. That rumbling is usually sediment build-up, and once it gets to that point, flushing doesn’t always help. I’ve seen tanks burst from waiting too long... not fun to clean up. Swapping it out before disaster strikes is definitely the safer bet.
I hear you on the tank bursts—my neighbor’s water heater let go last winter and it was a total mess. But do you think it’s always worth replacing just because of age, or is there any wiggle room if it’s still running quietly? I’m always torn between “if it ain’t broke...” and not wanting a flood in my basement.

- Age isn’t the only thing that matters. If it’s running quietly and not leaking, you might have a few good years left.
- That said, once you’re past 10-12 years, the risk goes up fast—saw one last week that looked fine outside but was rusted through underneath.
- Flushing the tank yearly can help, but hidden corrosion is tough to spot.
- Personally, I’d keep an eye out for any weird noises or water on the floor, but I wouldn’t rush to replace just because of the calendar. Sometimes these things surprise you and last way longer than expected... but yeah, it’s a gamble.
