- Convenient Installation: The user manual provides simple instructions on how to install this water pressure tank. You get a 1/4"quick-connect design out-of-the-box. All you have to do to complete the installation is to cut off the water outlet tubing of the tankless RO water filter systems, then insert both ends of the tubing into the tank. If your water pipe is 3/8", please contact customer service.
- Quick-fitting leakage:After installation, please confirm if PE pipe is cut smoothly. If not, cut the tubing squarely and cleanly. Make sure the tubing is fully inserted.
- Leakage between ball valve and the tank: Please check if there is a washer connecting the ball valve, if not, please contact us for a new ball valve.
- Water doesn't come out: Please check if the internal membrane breaks. Unsrew off the stem and you will see a protruding charging valve, then press the charging valve. If water flows out, it indicates the internal membrane breaks. Please change a new storage tank. If no water flows out, please contact customer service.
- NOTE: If you connect ro system to refrigerator through the mini tank, replace the filter in your refrigerator with bypass.

I've had a tankless RO system for 2 years now and I've just dealt with the low pressure going to my refrigerator. Finally, I decided to look up a solution and found this item. I decided to take a chance and lo and behold, IT WORKS! I was a bit nervous to cut my line to the refrigerator without know that this will actually work, but I took a chance anyways. I'm happy to say that I now have enough pressure going to my refrigerator from this to fill up the ice maker and make a glass of water before it starts to slow down again. But luckily, by the time it starts to slow now, the RO system is flowing and the water is steady. Previously, when I get water from my refrigerator, the RO system would turn on and then shut off constantly causing the water to just pump out slowly. Now I don't have this problem anymore.

So glad we got this to complement our Waterdrop RO. Our fridge icemaker did work okay without it, but we had to wait 2-3 seconds every time when getting water from the fridge dispenser for the water to start, which was annoying. This also caused the dispenser to initially drip each time before the pressure made it there, creating additional cleanup of the area and drip tray below. Now the fridge dispenses instantaneously like it did on a traditional setup. Initial water pressure at the sink dispenser is also greatly improved. Install was very easy. It comes with all materials needed and took just one cut of an included water line and plugging the lines in as instructed. All fittings are slip-in, so no additional tools required. I do understand this in a way defeats the concept of a tankless RO, but the footprint is much smaller than a traditional tank RO system, and maintenance is much easier and cleaner. Parts are all high quality. Previously when using the RO you could hear the tankless system running right away, with this mini-tank you'll notice there is a delay as the water from the tank is used initially then runs a few moments after turning it off to fill the tank again. Just something to be aware of. Would definitely buy again.

I have an all-in-one RO system (not Waterdrop) with an internal tank that gave out after just 18 months, causing the flow rate to slow to a trickle (3-4 minutes to fill a 16 oz glass). The system is not serviceable, but I read online that some users who faced the same issue solved it by adding an external tank. Sadly, they didn't post instructions, and it wasn't intuitive to me based on how the plumbing of my system works. That is, until I saw this setup, which matches the plumbing of my system. With it installed, pressure is great. It saved me from having to replace my system entirely. It has enough capacity for a glass of water, which is what I need it for 90% of the time. It barely takes up any space, and it comes with all the tubing and valves to hook it up in any configuration.

Added this since it is pretty much a necessity if you are also hooking up your system to a refrigerator ice maker. The added pressure for just a little bit also fills glasses much faster than without. Super easy to install, small size, great addition.

I have a Waterdrop 600 GPD hooked up to my fridge water dispenser/ice maker. For the first 6 months or so, dispensing water was slow to start (2-3 seconds), but the ice maker functioned just fine. After 6 months, dispensing water became slower and slower (5-7 seconds) and the water pressure was noticeably lower for the first 10 seconds or so. Then my ice maker start experiencing problems. The cubes became much smaller and it would take forever for the ice tray to fill up. My guess is that the use of the filters is what led to the slow degradation of the water dispensing slower and slower. The Waterdrop pressure tank immediately resolved all of the problems without replacing the filters. The water now dispenses instantly and the water pressure is great. The ice maker also now functions normally. My only complaint is that I wish I had known about this a long time ago. This thing should be shipped with all Waterdrop RO systems.

These are great units and really are needed with tankless systems and refrigerators. The sink faucet also gets a boost. I also added one to the inlet side to reduce the pump noise that could be heard in the water line in other rooms. I designed 3D printed wall mounts to make a clean installation under the kitchen sink. All in all I'm happy with the performance, however, the tank bladders failed in just over a year. I just bought a new pair but should they fail fast again will seek an alternate brand. Update, the Water Drops folks reached out to me and replaced my tanks. I really appreciate their helping out with this issue and hope this solves the issue as these are great for my application.

Easy to install and worked as stated. I combined this with a Waterdrop UV light as we recently got a scare from our local water company stating that water had a bacteria on one day and people were getting sick. I got the UV light to prevent this issue.
