This little tank, as an add-on to the G3P600 system, is a GAME CHANGER! The increased pressure you receive is amazing and makes filling large pitchers fast. I'm glad I got it but I think Waterdrop should include it in the main system and just charge a little more. You'd definitely improve your customer satisfaction ratings. Thanks for saving me money over the price of a water service.
I added this tank to improve the water pressure to my refrigerator ice maker, the instructions were just OK not great since I had to add the tank at a different place in the water line than what was shown in the instructions. It works fine and also increased the pressure at the sink tap. I gave it 4 stars since they don't provide a hanger for the tank.
Really improves the Waterdrop RO system. Eliminated the pulsing at the refrigerator and also eliminated the VERY slight pause between opening the faucet at the sink, and the water beginning to flow. The overall strength of the flow seems improved as well.
