## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well
*by L***N on September 3, 2019*

The initial pressure of the unit was about 110PSI, and it was high enough that I saw a drop of water come from something that had been sealed well (just a single drop, so it may have just been cause by expansion rather than an actual leak). My storage tank is rated for 50psi, so I had it turned off during the tuning of the shut-off switch. I kept adjusting until the pressure was where I wanted it, and was able to get exactly what I wanted out of it. It dramatically improved the performance of my water dispenser and ice maker by allowing me to double the output pressure of my RO system without exceeding any of the pressure ratings. An excellent upgrade to my system.

### ⭐⭐⭐⭐⭐ Works perfectly
*by A***L on November 16, 2020*

Works perfectly. You may have to do like what I did and uninstall the mechanical shut off system that your RO system might have. It looks like a four-way valve - you won't need it when using this.

### ⭐⭐⭐⭐⭐ Great product, even better support
*by J***B on October 18, 2020*

The product came as described and i was able to adjust the cut in at 80psi and cut out at 110psi. I did encounter a faulty switch but aquatec was KILLER in sending a replacement and I had the replacement next day. Wow, I couldn’t be more happy with this company and product. Highly recommend!!
