How to install REALice

Installing the REALice system is straight forward and requires a few hours by a certified plumber. Ensure that the REALice wall unit is installed securely to the wall.

  • The system is installed downstream of the final cold and hot water mixing line after any others systems (filtration, water softener or RO)
  • Coldwater can be used, however, it’s recommended to install on a mixing valve
  • It’s very important that 100% of the resurfacing water is treated by REALice.

The REALice wall unit is installed next to the ice resurfacers’ water filling station. The hose for the ice resurfacer is connected directly to the REALice system. Make sure that the REALice wall unit is not exposed to sub zero temperatures where there could be a risk of freezing water in pipes.


We recommend installing a mixing valve i.e. Leonard TM-80-AT-LF-RF (or ball valves) and a backflow preventer so all water used in the Zamboni room is treated through the REALice wall unit. The mixing valve helps to add a little bit of warmer water (max. 68°F).


This will be needed, if the arena isn’t well insulated and there is a possibility of the ice freezing from the top down when it’s extremely cold outside. A bit warmer water might also be needed during the transition to REALice (when applied to an existing sheet of ice) or when larger gouges from heavy user groups on the ice are observed. As the ice settles the gouges will get smaller over time.


We know there is usually a need for warmer water for general maintenance purposes and adding a mixing valve ensures that no non-treated water makes its way onto the ice.


There is a reduction in the water pressure as the REALice wall unit treats the water. The pressure reduction in the water fill line through the vortex process is 7 PSI. This leads to an increase in the fill time of the ice resurfacer of 10% – 15%.
