Small 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

This tank works exceptionally well. It doubled the flow on my tankless system (Waterdrop G3P600) and also resolved the hot-water flow issue. It’s compact enough to fit under the sink, which makes installation easy. While it may seem counterintuitive to pair a tank with a tankless system, it significantly improves convenience: the first few glasses are dispensed immediately, and the tank refills afterward while I’m not waiting.

I just received this pressure tank. It took less than 3 minutes to install and test. I am very impressed by this tank. I installed it in minutes and it solved the problem I had with pulsing water coming from my instant water heater. I couldn't believe how easy it was to install and use this tank.

Works as stated. The base is wide enough that we haven't had any issues with it tipping over. Found customer service to definitely lack and not helpfulat all. The product itself is fine.

We installed an additional RO faucet in our bathroom, using about 35' of 1/4" tubing from our kitchen system. Because of the long run of tubing to the bathroom sink, the flow rate was painfully low, 10 seconds to fill just 8 ounces. We installed this SimPure tank under the sink and PERFECT! Great water flow to fill a glass, 3 seconds to fill the same 8 ounces, while loosing virtually no space under the sink.

Most other RO systems include a pressure tank so I was somewhat dismayed that this was a required additional purchase to feed my fridge. Not really a complaint against the item, which performs as expected and is quite compact compared to other brands, but a comment on the brand itself.

This small pressure tank makes a substantial improvement in water flow from your R/O faucet. I have an R/O system from another manufacturer and installed this tank to improve the flow. Before the tank installation it took 6 seconds to fill an 8 oz cup. After the installation the fill time for 8 oz. reduced to about 3 seconds. The improvement in flow actually surprised me. Highly recommended.

We have a tankless RO system, but due to our connection to our refrigerator, we needed to add a small tank to minimize surging of the RO system. Initially we purchased a "mini" tank that worked well for about 2 years. When it failed, I started to re-order another "mini" tank and then came across this one. Here are the pros amd cons: Pros: 1. Takes up just a little more room as the "mini" tank, just a bit taller. 2. Capacity is about 3-4 times the "mini" tank. 3. Stopped all surging of the RO system whenever water was being dispensed thru the refrigerator (ice maker or thru the door). 4. Came with all the necessary connectors valves and Teflon tape. 5. THE WIFE COMMENTED HOW MUCH BETTER THE SYSTEM WAS RUNNING THAN WIRH THE OLDER TANK... HAPPY WIFE ... HAPPY LIFE. Cons: None so far, time will only tell how long this one will last. But when it goes, we will be getting the same as a replacement.

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.

Works verry well easy to install
