I bought this system to replace my older single filter Waterflop system which blew out and flooded my kitchen. After all, now I can have three filters that can blow out and flood my kitchen. Anyway, you would think Waterdrop’s hoses/fittings would be standardized. Makes sense, right? Nope. The new metal hoses do not work with the faucet that came with the original Waterdrop system I installed 2 years ago. Those water lines were white plastic with quick connect connections. These new ones are like the hoses you get at the local hardware store, save for those funky connectors that go into/out of the filter itself. You will need to either a) get an adapter or b) purchase the DM-100 Vmasstone faucet (that comes with a variety of adapters for different R/O and water filter systems.). I bought the new faucet, which by the way is sturdier than the Waterdrop system.Problem #2: the new inlet hose didn’t work with my T-splitter that I used for the old system. So I had to buy a new T-splitter. What I needed to get was a double female connector to hook up the inlet to the new T-valve. So now I am waiting on that to get here. Not happy.After multiple trips to the useless local hardware store (they sell everything no one needs) I called Waterdrop and was on hold waiting for 15 minutes. When the rep answered, as soon as I heard him speak I knew we were going to have a problem. His solution was to send me plastic tubing so I would be running a metal hose in and plastic tubing out. That’s not a solution. That’s called cutting corners. Not acceptable. Waterdrop is aware of this problem and you’d think they would throw in adapters for people using their old faucet so they don’t have to spend more money to buy hardware to make this thing work.Trying to install this system has been nothing short of a nightmare. I previously ordered this system then cancelled the order. Changed my mind and reordered it and am so annoyed, I want to box this crap up and send it right back. They sell this on the premise that people all have the same plumbing set up which is a faucet with two spigots, one for hot, one for cold. My set up is not like that. I have a faucet and a single handle hot/water spigot that pivots to change hot to cold and vice versa. This is why I need the T-valve splitter. Also the line from my dishwasher is plumbed into the main water line. It’s obvious the people at Waterflop never considered plumbing is not one size fits all. I have spent almost $100 on fittings/adapters/faucet/connectors to make this system work in my home. I’m thinking I made a mistake. Please be aware that installing this system is not as easy as you think. Also, it’s absurd that Waterdrop doesn’t include a faucet with this filter system. If you buy the one for Washington DC, you get a faucet. I don’t live in DC and I had a Wayerdrop faucet that wasn’t compatible with this system because there’s no adapter for the new hoses. You’ll have to buy that separately.The only reason why I did not buy a real R/O system is because I am limited on the space under my sink. That’s unfortunate because those would probably be less of a hassle to install.

Installed on kitchen faucet. Eliminated municipal water supply funky, chlorine taste. Only small reduction in water flow. I did not attach to wall, just set on cabinet bottom.

UPDATE: After using the filter for a few weeks, the water pressure started to increase a bit. It's now more than enough to not feel like I'm waiting too long to fill cookware, glass etc. Changed review to 5 stars!I'd read from several reviews that the water pressure reduction after the filter was installed wasn't that bad, but in my case it's about 50% less than before. HOWEVER, I can't argue with how well the filter system works. My cold water tastes incredible, and super clean. Reminds me of a bottle of 'Fiji' water, I was very impressed. 4 stars just for the water pressure drop, which I guess is to be expected with a 3 stage filter. Small price to pay for clean drinking water!

I can't give it 5 stars yet because I've only had it a week. BUT, I did a lot of research and found this product to be the best for my area. We have terrible water, that smells like it has more chlorine in it than my pool. This has absolutely gotten rid of that. It does change your water pressure (for cold water only), but to me that's a small price to pay for cleaner water. I ordered more for my other sinks and for my fridge water/ice cube line.
