Geyser Repair or Replace – What’s Best?

A faulty geyser isn’t just annoying—it can throw off your whole day. No hot water for a shower, dishes stacking up, or worse: water leaking through your ceiling. But when something goes wrong with your geyser, you’re faced with one big question: Do I repair it, or is it time to replace it?

At PlumbGuarantee, we’ve helped hundreds of homeowners in Stellenbosch and across the Western Cape make that call. Here’s what we’ve learned—no sales pitch, just practical advice.

Let’s Be Honest: Not Every Geyser Needs to Be Replaced

In many cases, a simple geyser repair is all that’s needed. If your geyser is relatively new (under 8 years old), and the problem is something like a blown element, a faulty thermostat, or a dripping safety valve (TP valve), you can often get it sorted the same day without breaking the bank.

Repairs typically cost a fraction of a replacement, and if the tank is still in good shape—no rust, no corrosion—it makes sense to fix the issue and get a few more years out of it.

But Sometimes, Replacing Is the Smarter (and Safer) Option

Here’s where we play devil’s advocate: not all geysers are worth fixing.

If your geyser is older than 10 years (some insurance policies cap the lifespan at 5–10 years), and especially if there’s any sign of a leaking tank, rust, or repeated issues, replacement is often the safer and more cost-effective choice.

Why?

• A leaking geyser tank cannot be repaired—once the cylinder is damaged, it’s done.

• Repeated call-outs and part replacements can add up to more than a new installation over time.

• Older geysers are less energy-efficient and more prone to failing under pressure.

It’s also worth checking your home insurance policy. Many will only cover water damage if the geyser has been maintained and isn’t older than a certain age. That makes proactive replacement a smarter call in the long run.

Bonus: Think About Energy Efficiency

Modern geysers, especially those with insulation rated above Class B, can help you save electricity. If you’re running an old Kwikot or Heattech unit from more than a decade ago, you might be paying more every month in electricity than you should be. Geysers are among the biggest energy users in a home—upgrading to a newer model can help cut costs in the long term.

And no, you don’t have to go solar just to save energy. Even a new electric geyser with a timer and a blanket can make a difference.
