IS THIS RIGHT FOR YOUR HOME?

Match the treatment to your needs.

Homes seeking more cabinet space and higher rated drinking-water production.

We confirm cabinet clearances, required connections and power, water suitability, and the selected faucet before installation.

What changes when you go tankless?

Water is produced on demand instead of stored in a separate pressure tank. The HW800 adds a built-in alkaline stage and a higher published production rating. Your water conditions and installation still determine real-world output.

Ratings are not guaranteed household output. We confirm dimensions, power requirements, filtration-stage details, and model-specific cartridge replacement intervals for your installation. RO is not a substitute for disinfection of microbiologically unsafe or unknown-quality water.

Care & ownership

Follow the supplied cartridge and membrane replacement instructions. Quick-connect cartridges simplify replacement, but the system still needs maintenance. We confirm replacement parts, intervals, and costs for the supplied model; the seven stages do not mean seven separately replaceable cartridges.

Warranty & support

Coverage varies by component. Review the coverage periods, conditions, and exclusions, and contact Best Home Water for help.
