I don’t but I live by my little lonesome, wash small laundry loads, and like short, warm showers.
That’s probably how I got the old one to last over 20 years. It was a Rheem 40 gal NG heater and came with the house. No problems til this week. Probably full of sediment by now.
And they tell people to swap them out every ten years. They lie.
The older stuff was definitely made more solid so we see some water heaters lasting 40 years. You and I live in mega blue territory so due to all the excessive tree hugging and regulation, our cost of living is much, much higher than say, Kentucky.
If you are hard up, flush it and swap in a new anode. Could last much longer.
Probably need to replace the sacrificial anode, aluminum or magnesium, usually about every 5 years, YMMV. Water smelling bad? First sign anode got eaten away. It’s not a difficult DIY task, drain and flush tank at same time. Simple threaded nut at top of rod, drops into tank from top. If you have a manual you can get a part number, but the nut is virtually universal, though length varies according to tank size and type. Can even buy them from Amazon, $25-30 delivered. Tried buying one from local plumbing supply, they were asking $70.
