If you’re not handy, professional installation might be another $150 to $300. For complex setups—like connecting to a fridge or adding a UV lamp—it could hit $500.
But here’s a rhetorical question: How much is your time worth? If you hate crawling under sinks, paying a pro is a no-brainer. If you love DIY, you save that cash for a nice dinner.
Fun fact: Some store-bought systems include free shipping and a pre-paid return label. So if you mess up, you can always send it back!
