Float Level Controller for up to 80 GPD RO/DI Systems (CSP and CSPDI)

SpectraPure® Float Level Controller provides an economical way to automatically fill open reservoir storage tanks. The automatic shut-off valve, in conjunction with the mini-bladder, provides positive shut-off and completely shuts off the waste water and product water lines, thus conserving water.

The Float Level Controller includes an ASO valve, stainless steel float, check valve, mini-bladder tank, a straight ball valve, tubing and necessary fittings.

Buy one float kit for filling every additional sump or reservoir. SpectraPure®’s Float Kit includes a stainless steel float, union T, and other necessary fittings. The installation of float requires a 9/16” mounting hole in the tank.

Note: The Float Level Controller is not recommended for evaporation replacement in aquariums. For these applications, we recommend either our SpectraPure® Single Tank Liquid Replenishers or Multiple Tank Liquid Replenishers

  • For unattended filling of tanks, reservoirs and sumps
  • Positive shut-off; completely shuts off all waste & product water
  • Use for the automatic filling of multiple open reservoir storage tanks
  • Reservoirs can be located as much 50 feet away from the RO or RO/DI system

Works Fantastic!

Easy to install and works great! I really needed this. This is about as automatic as you can get. Keeps my RO storage tank refilled without me needing to worry. From there, my ATO takes over and my water levels and salt levels are dead on!

Great Product

Seems to work great. No problems at all but only recently installed. Using this on a fresh water reservoir for my tank. A bit expensive for what it is, but SpectraPure has a great reputation.
