Good taste suggest add a pressure water tank

My system is split to a dedicated faucet and my 2 refrigerator's, ice makers and water dispensers. Water taste good, no issues. I did have to add a small pressure tank to keep the system from cycling multiple times when the ice maker was being filled or the water was being dispensed from the refrigerators. The refrigerators back pressure causes the RO system to shut off prematurely. With the added small waterdrop PWT ( pressure water tank) the system no longer Cycles and the pressure of the water coming out, has increased a small amount. The number of times per day the system comes on has also decreased because of the PWT. The system is not loud but noticeable. The reviews I've seen mainly complain about noise from the system. Which it's not my experience. Again, adding the PWT also reduces the numbem cycles the system runs per day. The system was easy to put in. Only pre-requirement is a dedicated electrical outlet under the sink. I split my power from my dishwasher. I ran my electrical line from the dishwasher under my cabinet into a dedicated dual Outlet. Plug my dishwasher into one side and the RO system into the other side.

Convenient and fresh-tasting water

[This review was collected as part of a promotion.] We recently installed the Delta Clarifi tankless reverse osmosis system, and I've been really happy with it so far. The water tastes super clean and fresh and comes out fast since there's no tank slowing things down. It also doesn't take up too much space under the sink. Installation was pretty straightforward, and filter changes look easy when it's time. One thing worth noting is that, like most RO systems, it removes pretty much everything from the water, so we purchased a remineralization cartridge (sold separately) to put healthy minerals back in. Not a downside, just something to plan for if you are thinking about purchasing this. You also need to purchase a separate faucet. Overall, it's been a great upgrade and totally worth it for the quality and convenience.

Great reverse osmosis system

[This review was collected as part of a promotion.] I'm really impressed with this filtration system! The water tastes super fresh and clean, such a big difference right away. I also love that it's small and doesn't take up much space under the sink at all. My husband was able to install it pretty easily, which was a huge bonus. Overall, a great upgrade for our kitchen and totally worth it!
