A homeowner dealing with a leaking Rheem water heater turned to Reddit for advice — and users did not hold back with their recommendations.

Rather than replacing the unit with another big box store model, commenters urged the homeowner to take a look at what caused the failure in the first place.

Here's what to know

The post on r/HomeMaintenance described a 50-gallon, 42,000-BTU natural gas water heater and about $700 in Home Depot store credit.

"The current water heater failed in less than 5 years so it's still under warranty. But I want to get something better in terms of build quality," the original poster wrote.

One commenter wrote, "Bradford White through a supply house. Skip the big box store units entirely."

Someone else pointed to options in the $700 to $900 range and added: "40k BTU vs. 42k won't change your hot water. Recovery spec is what matters."

More background

Even a pricey replacement may not last as long as expected if the issue is hard water, high water pressure, or missing protective components.

If you want to cut down on energy bills, switching to a heat pump water heater offers a smart way to start saving.

What can be done?

Before paying out of pocket for a new tank, the first step is to explore the warranty.

There were many possible causes raised in the discussion.

"Worth checking why it failed before you spend anything, because a tank dying in under five years usually means high water pressure, no expansion tank, or a sacrificial anode that got eaten fast in hard water," one commenter wrote. "Whatever brand you buy next will go the same way if the underlying cause is still there."
