You don’t really notice how much bottled water costs until you’re standing at the servo on a 34-degree day, grabbing two bottles without thinking, and the total flashes up: $9.80… for water. It feels harmless at the moment, but if you live in Adelaide, with heatwaves getting earlier, longer, and honestly a bit relentless, those little purchases pile up faster than most households realise.

And that’s where the idea of whole-home filtration suddenly makes financial sense. Not just “health benefit” sense or “eco-conscious” sense, but plain numbers. Dollars saved. Waste avoided. A system that pays for itself simply by replacing a habit we barely question.

aba PLUMBING + GAS has partnered with PurEco Whole Home Water Filtration Systems, and to be honest, the timing couldn’t be better. With the hot weather creeping up and bottled water prices quietly edging higher, people are finally asking: Is this really the smartest way to get clean drinking water?

How much are you really spending on bottled water?

Most Adelaide families go through far more bottled water in summer than they realise. Take a standard household of four:

• One bottle each per day in warm weather (a very low estimate)
• Around $3 a bottle 
• That’s $12 a day, around $360 a month
• A summer total (Dec–March) of about $1,400, just on water you throw out after drinking

And that’s conservative. Plenty of families buy cartons, keep extras in the fridge, take them to work, school, sport. Some spend double that without blinking.

A whole home water filtration system — installed properly — usually pays itself off in the first two years, sometimes sooner. After that, you’re basically drinking filtered water for free.

The maths is surprisingly clear once you stop treating bottled water as an “occasional” purchase.

The quieter costs nobody calculates

Beyond the money, there’s the waste like bags of bottles filling the yellow bin, especially after hot weekends. Even with recycling, it’s still energy-intensive. There’s also the inconvenience of always running out. 

Whole-home filtration removes that cycle altogether. Clean, filtered water at every tap. The shower, the kitchen sink, even the garden hose benefits because Adelaide’s water quality can fluctuate after storms or heavy rains and that affects more than drinking.

What makes whole-house systems better than those counter jugs and small filters?

A PurEco system works across the entire property. Every tap. Every shower. The washing machine. The bathroom basin where kids brush their teeth half-asleep in the mornings. Even the pipes get less scale buildup, which many homeowners don’t realise until we point it out during a service call.

It’s a bigger home investment, similar to installing solar. But just like solar, it lifts long-term value, reduces running costs and makes the property itself better equipped for South Australian conditions.

Is it really worth upgrading to whole-home filtration?

Most families think filtration is just a wellness product. Something extra. But when you lay out the numbers and the lifestyle benefits, it leans firmly into the smart home improvement category.

You get:

• consistently clean water
• stable filtration even after heavy rains
• fewer plastic bottles leaving the house
• predictable yearly costs (unlike supermarket pricing)
• and long-term savings that grow every summer

On top of that, a PurEco system is built for Australian water conditions, Adelaide’s especially — which isn’t something you get from cheap off-the-shelf filters.

If you’re already buying bottled water, you’re already paying for filtration – just in the most expensive way.

You’re already spending the money.  A filtration system simply redirects it into something permanent, efficient, and far more practical.

aba PLUMBING + GAS can install PurEco systems cleanly, explain the maintenance, and help you choose the right configuration for your household size. No overthinking. No complicated comparisons.

Just a solution that stops the waste both financial and environmental and gives your home better water right from the first turn of the tap.
