SimPureSmall Water Pressure Tank for Tankless Reverse Osmosis System, RO Water Storage Tank with Fittings for Refrigerator, Ice Maker, Suitable for 1/4" and 3/8" Water Pipes

We added an Ispring Tankless RO water system under our sink, but you need an additional pressure tank for the fridge/Ice maker connection. We chose this due the small size. It works great! Now we have great ice & water and an additional bonus is the increased water flow & immediate responsiveness at the tap. My husband did have to get some additional fittings/adaptors to make it work, but well worth it. Highly recommend.

Who said bigger is better? In this case small is much, much better. It takes up so much less room than my previous tank with my previous RO system. I highly recommend the Simpur system.

Helped the water pressure to my refrigerators water and ice as the tank in my RO needed a booster tank

Bought this so I could run a line to my refrigerator for the ice machine. Was simple to hook up, instructions were good, and the ice machine works great. Also the added benefit that the tap produces water faster. Not a large tank, it runs out after a couple of cups the the speed drops as expexted. But my use was the ice machine primarily and it works flawlessly.

It works great.

Seems good quality with no leaks. Strangely, they include a 3/8" 3-way connector, but it will not fit the 1/4" tank ball valve. Should have included a 3/8" ball valve since they advertise it is for both 1/4" and 3/8" systems. They don't even sell them, so it required an additional purchase (the John Guest valve works fine with an additional o-ring: "John Guest 3/8 OD x 1/4 NPTF Inch Female Adapter, Push to Connect Plastic Plumbing Fitting, PP451222WP"). Also, didn't help raise the pressure or increase the water flow to my refrigerator even though I convert that line to 3/8".

Works great

easy of installation
