Coffee is made up of 99% water. The quality of the water used in your coffee has a direct effect on the quality of your coffee. Don't believe me?


Let me tell you about a terrible experience a cafe owner recently had. Then I’ll show you how to avoid the same costly experience.

A few months back I was called to a popular cafe to fix an espresso machine. An angry buzz was emanating from inside the machine every time water flowed. The baristas thought it was possessed. And the customers were frightened.

After some poking and prodding with my crescent wrench and volt meter in hand, it was discovered that a solenoid (an electronic thingy that lets the liquids flow) was buzzing. I replaced the damaged part. And then another part was replaced. And then another. It got to the point where I had to take the espresso machine completely apart.

Once I got the boiler opened up (where the steam is made) I found, no joke, nearly enough sand-like scale to fill your bathroom sink! Every part of the machine that water touched had to then be taken apart and cleaned. You must be saying to yourself, “Shoulda had a water filter.” Well they did, a pretty good one at that. However, it was insufficient for the brackish water supply typically found in Southern California. We have some of the worst!

Running hard water through your espresso machine can cause limescale build up. Overtime, pipes could narrow and damage the basic function of your machine. To make matters worse, this puts the taste of your delicious coffee at risk. As you can see, this is quite the scary snowball effect. Luckily, there's an easy fix.

A Reverse Osmosis System will allow you to manage the water that flows through your machine while protecting your investment and avoiding downtime. Aside from that, you will be more confident knowing your water measures up to ambitious specialty coffee standards.
