XT Small Water Pressure Tank, RO Pressure Tank for All Waterdrop X8/X12/X16 Reverse Osmosis System to Connect the Refrigerator, Mini RO Water Tank Fits 𝟯/𝟴" Water Tubing

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.

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.

Works well with my reverse osmosis system. I used this to hook up the refrigerator ice maker.

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.

Didn't seem to help much with pressure compared to my previous tank based RO filtration system that supported the same three outlets (faucet, fridge, hotwater), but did not try removing it after installation. The pump kicks in immediately in the RO system as there is not much capacity in this small tank. It likely gives you an illusion of water rushing through early on, but almost immediately teh RO system kicks in.

Bought this product to supplement an X12 system I was installing. SinceI have a long run over to my refrigerator for the ice machine, I was under the impression the small tank would ensure consistent pressure and water delivery. Unfortunately the included distribution valve reduces output of the X12 by approximately 30% to 50%. I tried removing it and only using the tank, but that causes the pressure to be too high at the faucet when first turned on. In the end I only ended up using the long 1/4 tubing and tee fitting included in the kit and essentially wasted money on the rest. Since the X12 has a built-in pump, I'm going to tee the refrigerator supply line off the faucet line and expect it to work fine.

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

It works to connect the Waterdrop X12 to my refrigerator. I wish the 1/4" tubing that came with it was a little longer for my setup. I ended up buying additional tubing for it to reach. It increases the water pressure needed for the refrigerator water/ice maker. It also increases the pressure for the X12 faucet. Use this in conjunction with SharkBite 1/4-in OD Push-to-Connect x 1/4-in Compression Female Adapter to make installation easy.
