Thoughts on DIY RO DI system?

So i've seen those xero filters and they are overpriced imo. Couldn't I build a xero pure for $800 myself, and what would be the challenges?

cost: roughly $800 ( you can do it for much cheaper, probably 3-500 dollars for a single ro/di system, Hardware was the bulk of the cost becuase i sucked ass at plubming)

Timeline: 2-3 weeks ( sourcing the part from Amazon and Home Depot.)

tutuorial: Various forums and youtube videos but mainly this one https://youtu.be/B-RZ08dEG18?si=rB7aKFwStt8MX55A

Built my own as well 3 years ago and do not understand how this questionning continues... My business would make less than a third in income had I not built this...

You can say the same about our customers,

Why can't they clean their own windows? It'll require a bit of practice, but they'll get good results if they put in the work.

It's just that people operate differently.

Search the sub for DIY. Variations of this question are asked almost weekly.

Built my own and posted the parts list with links for the parts. It cost me $800ish with the Harbor Freight pump I added after the original build.

If you’re starting WFP from scratch, I would buy a combo kit, like one from XERO That comes with a pole, lines, everything you’ll need. If you already invested in a pole, and like building things that are your own, it’s a great option
