## Description

Pressure Mini Water Tank

Review: 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.
Review: 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
