Great upgrade for older fountains

Upgrading older fountains without a bottle filler was a huge improvement. The unit works well in high-use indoor facilities, and customers have made positive comments about the bottle-filling station. We received the units quickly and would recommend them for facilities where people frequently use water bottles.

Saving the Planet

Since installing the Elkay LZWSRK retrofit bottle filler, our guests are enjoying filling their water bottles and we no longer have to purchase 5-gallon water jugs to accommodate our team members and guests. Could be a great investment.

We bought two single bottle filling water cooling machine, one bi-level water cooler with a single filling, and one bi-level water cooler. It was an easy ordering system, fast delivery, and great communication with the company. I would recommend buying from them as they have the best deals on water coolers. Great bunch to work with.
