house Heaters For Sale

How much is a 5 year old electric water heater worth? How long do they typically last?
a woman at work has a 50 gal electric water heater for sale. They are building a new house and going with gas. My water heater runs out in about 7 mins and is about 20 years old….assume it is filled with sediment. Is it worth buying a lightly used one for $40?
I wouldn’t. Water heater life spans suck. The used one is probably loaded with sediment/mineral deposits. If it has a sacrificial anode, it may be almost used up as well.
I’m betting that the reason yours can’t keep up is its age and sediment.
