Keep your RO/DI reservoir from overflowing

The IceCap Adjustable RO Float Valve provides a mechanical stop at the water level you set in a storage reservoir. It is a practical finishing piece for a reef keeper's RO/DI mixing station and pairs well with the IceCap RO/DI systems in our shop.

Fit and setup

• Connects to standard 1/4-inch RO tubing with a quick-connect fitting.
• Mounts through a 1/2-inch hole in a reservoir wall up to 1/4 inch thick.
• Adjust the float position to set your preferred fill level.

Installation note: A float valve stops water at the reservoir; a properly configured automatic shutoff valve and check valve are needed for an RO/DI system to stop its feed and waste flow. Verify your particular system's plumbing and pressure rating, and test for leaks and correct shutoff before leaving it unattended.
