Looking for a way to improve your water quality at home? Reverse osmosis (RO) water filtration eliminates contaminants and takes the guesswork out of your brewing water. At Lancaster Homebrew, we proudly offer Waterdrop tankless filtration products, providing you with pure water on demand and the putting the mineral content of your brewing water firmly under your control.

How It Works:

  • Filtration Process: Reverse osmosis systems use a multi-stage filtration process. Water passes through sediment filters, carbon filters, and finally, a semi-permeable membrane with microscopic pores that block impurities. Once connected to your tap water source, our Waterdrop tankless RO systems perform this multi-stage filtration process, ridding your water of sediment, chlorine, heavy metals, and dissolved solids.
  • Real-time Monitoring: Every drop matters, and that’s why our RO systems come equipped with a digital at-tap display. This feature allows you to monitor total dissolved solids in real-time as water exits the tap, ensuring you always have the purest water flowing in your home.

Benefits of Reverse Osmosis Filtering:

  • Improved Water Quality: Level up your home’s water quality with crisp and clean H2O on demand. Our Waterdrop systems offer efficiency and space-saving benefits, making them a seamless addition to your kitchen.
  • Brewing Advantages: For homebrewers, our RO systems offer more than just purified water. By starting with a blank slate, you gain the power to customize water profiles by adding minerals back in. This level of precision allows you to accentuate specific characteristics in your beers, providing a canvas for creativity.
  • Historical Profiles: Recreate historic and regional brews by emulating locational profiles. When you start with RO filtered water, you can tailor your water it to mimic the mineral content of renowned brewing regions, adding authenticity and depth to your homebrew.

Tank vs. Tankless Systems:

  • Tank Systems: Traditional under sink RO systems have a storage tank to hold purified water. When the tap is turned on, water from the tank is dispensed, and the system then refills the tank to replenish the supply. This type of system does the same work as a tankless system but in a slower and less convenient manner. The tank adds additional complexity to the system and takes up more space.
  • Tankless Systems: Tankless or on-demand RO systems skip the storage tank, providing a continuous flow of purified water. These systems are compact and efficient, making them an excellent choice for those with limited space. There’s also no time wasted waiting for the tank to refill.

Waterdrop Tankless RO Systems:

  • Multiple Sizes: Our Waterdrop tankless RO systems come in multiple sizes, including 400GPD, 600GPD, and 800GPD. Choose the capacity that aligns with your daily water needs and brewing aspirations.
  • Ultra-Large Capacity: The 800GPD system means that the reverse osmosis water system produces a staggering 800 gallons of water per day. Ideal for large households and small businesses, this system ensures a continuous supply. Additionally, the fast water flow fills a cup in just 6 seconds, eliminating the wait for pure water.
