Just a quick follow up on this. So far the new RO system has been absolutely amazing. I'm a pretty tough reviewer. I don't suffer bad stuff easily. So, if you were to find my review of the system on Amazon you'd see a glowing 5 Star review. And I cannot remember the last time I gave something 5tars. But, the quality of this device, value, and support from the company whenever I've had a question or concern. Honestly can't find a negative to point out.
Really my only small gripe is the faucet requires a 1" opening in the sink/counter top. Others only 1/2". So not wanting to deal with trying to open the previous hole I removed my soap dispenser. No big deal. Wasn't enamored with it anyway. So, with the dispenser removed it dropped right in. Hookup is dead simple as well.
So, I left the old faucet in place and simply reactivated my hard/mineral water system (filtering straight from street service. I do like that water for a drink now and then. It's too hard for properly running the coffee makers/ice maker and such. But it tastes good for a glass of water. Was no skin off my nose to simply reactivate it.
But otherwise I cannot say enough good about this Waterdrop system. It even has remineralization built in. So no need for a separate system to do it as before.
And it's FAAAAAASSSST. When you open the faucet a light hum comes on from the pump and it runs water out REALLY fast. Added benefit my ice maker works better than ever, the fridge no longer needs a filter so I've bypassed it no need to buy replacements here. If you find yourself needing a system IMO almost anything from this company
