XT Small Water Pressure Tank, Fits 𝟑/𝟖" Water Tubing | RO Tank Compatible with X8/X12/X16/G3/G5 RO System to Connect Refrigerator or Ice Maker, Built-in Diverter Valve, BPA-Free

Pressure tank for the win. RO system wasn't handling making ice with the new fridge. Installed mini tank and couldn't be happier. More pressure at the faucet is nice also. Fit under the sink without taking up to much space and came with everything needed for a easy install.

Works great! Gives the extra pressure I needed!

All the needed pieces are included and the paper instructions were ok; we found a video that was very useful when installing. At first, we bought this add-on because our new refrigerator ice maker (on the other side of the kitchen about 12-15 feet away) was not working but another appliance on the same dedicated filtration line (built in coffee maker) was, so we thought it was a pressure issue. After installing the pressure tank, the ice maker still did not work so we pulled the refrigerator out and the ice maker eventually kicked on...we think we had a kink in the line to the ice maker but not 100% sure as we attempted a bunch of fixes and really don't know what the issue/fix was. It works great now although water from the filtration spout come out fast--enough to splash out of the glass and we wonder if the pressure tank is contributing to this, but it is better than not having ice, so we are leaving it as is for now.

This works, but it is expensive for what should be basic and included functionality, includes excessive additional components, and is overly complicated to install. Rethink and reengineer, please! The Waterdrop X12 base unit does include connect to your refrigerator. All refrigerators these days include water and/or ice and require a water line connection. Most or all purchasers will want this accessory to add their refrigerator to the X12 filter. It should not be an expensive extra. This unit is overly complex. Rather than a simple "T" to connect the filter to the refrigerator, this includes a mini pressure tank and a 3-way value. I don't know why these are needed but Waterdrop says that they are. The 3-way value and maybe the pressure tank could easily be incorporated into the main unit. The installation is overly complicated. After installing the X12 unit, I had to cut into the water supply line and the filter line and make 12 different water line connections to get everything connected. These parts and all of the new lines crowded my undersink space. The unit appears to work fine.

I got this to go in line with my reverse osmosis system that feeds directly into my fridge. I assume it works well since the pressure keeps up. I never tried the system without it.

Added this to my Waterdrop 1200 it was easy to add I purchased a longer piece of pipe approx. 30 ft to connect it to my fridge a s although my fridge is only 12 feet from the unit I needed to route it down into my basement and have enough slack to pull the fridge out if needed. This caused no pressure problems at the fridge for water or ice making.

I bought 3 of these, The first 2 had bent O-rings in the distribution valve that caused major leaks, no way to fix it. The 3rd one was finally not defective and worked normally. Assuming you get one that actually works… it does its job as intended
