Best Decision Ever

This system replaced a Sparkletts rental system I had for over 20 years, the water from this new system provides a better tasting water product.

New reverse osmosis system

It took a while to get the conductivity reading of the output down to acceptable levels but it is working well now.

Product was great!

Directions could be better. Sanitation directions were vague. I also wish a bit more tubing was provided.
