Big & Beautiful UV Minirack System

Just installed this a few days ago and I’m very happy with the quality of the water. The water (from the lake) looks clear and tastes great. I will get it officially tested after the long weekend.
You’ll be impressed when you open the box containing this Mini-rack; it’s big, bold and beautiful. The filter canisters are about 24” long and probably 6”-8” in diameter, and the UV Chamber is probably 22” long.
I learned a lot from watching Gary The Water Guy’s videos, they are informative and help simplify the installation. I also watched his video to sterilize and disinfect the plumbing pipes which worked well. Note to collect (in a bucket or through a hose)
or discharge the chlorinated water outside, so as not to kill the bacteria in your septic system.
Overall, I’m very happy the product and service from the Water-e-Store. They answered all my questions and I would highly recommend this product.
One other tip I would recommend is the make sure you buy the version WITHOUT the “E” suffix, so in future, you can add a solenoid control valve to shut off the water valve in case of a power failure. I hope the add the solenoid control valve in future. If you buy the MR400-E, version, you WON’T be able to have this option in future.


Thank you for taking the time to leave such a detailed review of our UV Dynamics 13GPM Minirack system. We're thrilled to hear that you're already noticing a difference in the quality of your water and that our videos were helpful in the installation process.

We appreciate your recommendation and are glad to hear that our team was able to assist you with any questions you had. Thank you for the tip on purchasing the version without the 'E' suffix for future options.

We hope you continue to enjoy your new UV Minirack and please don't hesitate to reach out if you need any further assistance.

Best regards,
The Water-e-Store team
