Frequently Asked Quetions

How soon can I get this if I order today?

We ship all in-stock orders the same day when an order is received before 2PM EST. Depending on where you live, the shipment will take up to 7 business days to arrive. You will receive tracking information via the email provided on the order details.

Who should consider a UV disinfection system?

We recommend UV disinfection for families living in areas with frequent boil water alerts, homes with private wells, and homes with drinking water that contains high total coliform bacteria.

Will UV treatment get rid of iron bacteria and/or sulfur-reducing bacteria?

We do not recommend UV for the disinfection of water with iron or sulfur bacteria. With over 600 different types of iron and sulfur bacteria, and the jelly-like membrane the bacteria have, the UV light would not be able to properly penetrate the membrane of the bacteria to disinfect the water. Consider a chlorine injection system with retention to kill iron or sulfur bacteria.

Why is it recommended to pre-treat the water before installing a UV Premium System?

We recommend a 5 micron sediment pre-filter to remove dirt and debris. The quality of your water can affect the dosage of UV disinfection the system provides and can cause premature "sleeve fouling," which will require the sleeve to be cleaned more often and may damage the UV sleeve. Pretreatment safeguards against these possibilities.
