Yes, older systems can be a bit thirsty. They might waste four gallons for every one they make. That’s a lot of water going down the drain. But modern models are much smarter. Some waste almost nothing. Do your homework.
Also, RO water is very pure. Very pure. Some people worry it’s “dead water.” They say it lacks minerals. True, it removes calcium and magnesium. But you get those from food, not from your shower. Eat a cheese stick. Don’t worry about it.
The hilarious reality of installation

You’ll also need a drain line and a pressure pump. It’s a bit like turning your utility room into a mini water treatment plant. But the payoff? You can drink from the garden hose without grimacing. Game changer.
Pro tip: if you have well water, you might need extra pre-filters. Well water loves to bring friends—like iron and mud. The RO system will handle them, but give it a pre-filter so it doesn't get overwhelmed. Be nice to your membrane.
