Is reverse osmosis water bad for you?
The process of reverse osmosis does not make the water unhealthy in any way. Rather, the purification benefits may protect you from many water-borne contaminants.
Can this reverse osmosis filter be used for hard water?
Yes, this machine can be used with hard water, and the TDS reduction rate will be 90% and above after complete flushing. But we do not recommend using it as a source for the RO system directly, you can install a pre-filter first, like Reusable Whole House Spin Down Sediment Water Filter.
What’s the difference between tankless and tank reverse osmosis systems?
Tank reverse osmosis system holds reverse osmosis water so you have plenty to use when you need it. A traditional tank reverse osmosis system makes water slowly. It takes one minute to produce two to three ounces of RO water. If you were to turn on your faucet for a glass of water at the actual membrane production rate, then you would have to wait at least 5 minutes for it to fill. Waterdrop tankless reverse osmosis system has overcome the issue of bacteria colonizing in the bladder tank. With no storage tank to fill, Waterdrop tankless reverse osmosis system does not run until RO water is needed.
Do I need plumbing services to install the reverse osmosis system?
No. Waterdrop RO systems are designed for DIY installation. You can install the system in 30 minutes. Simply refer to the instruction manual and instructional videos, or contact us by email, phone, or live chat.
This video explains how to install Waterdrop RO system.
