Waterdrop PMT Small Water Pressure Tank, RO Pressure Tank for All Tankless Reverse Osmosis System, Mini Reverse Osmosis Storage Tank Fits All 1/4" Water Tubing, Small Water Tank for G3, G2, D6, PD600

I purchased this small stand alone tank to go with our Waterdrop system that we installed. It comes with all of the parts and pieces that you need to attach it to your system so that your water runs through the RO system and fills up the tank, and in my case, feeds the faucet above as well as the refrigerator. It does allow us to fill a glass of water up much faster than going straight from the RO system because the tank is already filled, and it pulls from the tank quicker than just straight through the RO system. In doing my research, I read that if you’re going to have your refrigerator hooked up to your RO system, you would need a tank to provide more pressure to get the water to your refrigerator for ice and water, so that is the main reason that we bought it and it works quite well. It integrated with our current Waterdrop RO system quite well and quite easily. If working with this type of stuff intimidates you, don’t let that be a deterrent, the 1/4 inch hoses snapped in quite easily to all of the parts and components and they have a little blue clips to hold them in place so no leaking. In other words, it doesn’t take rocket science to put it all together and the instructions are quite simple. The only drawback I found with this particular tank is it has a very small pedestal and does not stand up very well, especially with all the quarter inch hoses attached to it so it tends to be top-heavy. I plan on finding some type of bracket to attach it to to hold it to the side wall so that it doesn’t fall over and roll around underneath the sink. But other than that, I highly recommend it, especially if you have a refrigerator that you want ice and water too.

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.

Wonderful system. Easy maintenance and the ro water system functions as advertised. The only drawback is the unit is noisier than a home unit should be.

The Waterdrop PMT small pressure tank along with our G3P800 Reverse Osmosis System solved all the water pressure issues that we had with our previous tanked RO system. The water dispenser and ice maker in our refrigerator/freezer finally have the proper water pressure needed. No more frozen water lines to the ice maker or waiting forever to fill a glass of water. Our water is safe to drink and tastes great! The customer service that Jessica C. from Waterdrop provided was outstanding as well. She went out of her way to make sure our issues were solved. I would highly recommend any product from Waterdrop.

I'm using a SimPure T1-400 Reverse Osmosis system and when connecting it to my refrigerator it would create a pulsing sound which was annoying. I purchased this to see if it would help and to my surprise it totally fixed the situation. The install is super easy because they actually give you all the parts you need. I was so happy I bought a second one for another property I have with the same system and problem. Its small size makes it easy to hide under the sink. Very good item if you have a similar problem.

The unit is very good and the customer service is amazing!! My unit had an issue and Krystal resolved it quickly and made sure everything worked out 100%. super happy and thankful that the customer service team was so responsive

Imprescindible si tienes un sistema de ósmosis de flujo directa sin depósito.No ocupa nada y el agua sale a tope desde el principio y sin esperas.

Used to help push water to refrigerator water dispenser. Easy installation and working great.

I dont feed my RO to my fridge yet. I got this to improve the pressure on the faucet, took 14 seconds before to fill up 1 cup, after i installed this, it takes 6-7 seconds. love it! I think this should be included when you spend $700 on your RO system in the first place.

was easy to install. because of the size, check your measurements to insure it fits in your space. the water tap could be a little larger.
