Aquarium float valve kit offers a simple solution to maintain proper water level. Use the Eshopps Float Valve as part of an automatic top-off system you create to replenish aquarium water lost through evaporation. Adjustable acrylic mounting frame allows a full 6 inch range of water level adjustment for versatile installation options. Features nylon screws (no metal parts) for corrosion- and rust-free use. Includes 3-1/2" x 2" dia Float, Valve Assembly, 1-5/8" x 1-5/8"x 7" high acrylic mounting frame, and a 7 foot length of 1/4" tubing that attaches to your water source.

• SpectraPure Model ASOFK
• Positive shut-off; completely shuts off all waste and product water
• The Auto Shut-Off Float Kit is not recommended for evaporation replacement in aquariums. For these applications we recommend either the SpectraPure Automatic Liquid Level Controllers: Single Tank Liquid Replenisher.

Includes:

• Auto Shut-Off (ASO) Valve. Pressure-operated device that shuts off the water supply to the RO membrane when the product line pressure equals 2/3 of the supply line pressure.
• 1# Check Valve. Prevents pressure in the product water line line from leaking back into the RO membrane.
• Float Valve. Installed in conjunction with the ASO valve. shuts off product water going into the open reservoir.

• For automatic replenishment of evaporated liquid and liquid level control on single tanks, sumps or reservoirs
• Safe low voltage operation
• Automatically turns off in the event of a power failure
• Longer membrane & filter life
• 5 feet of Remote sensor tubing provided (custom lengths available)
• Additional switched 24 volt AC outlet for controlling booster pump or other 24 volt AC operated devices
• Safety backup float

SpectraPure Single Tank Liquid Replenishers are the most advanced means of controlling liquid levels on single reservoirs, and are ideal for replenishing evaporate water in aquariums or liquids in other constant level containers. An onboard air pressure activated electrical switch opens a solenoid valve when the liquid level drops approximately 1" and closes it when the liquid level rises back to its original level.

Research at SpectraPure shows that the Single Tank Liquid Replenisher provides a significant advantage over conventional float and back-pressure activated automatic shut-off valves by maximizing the duration of membrane operation.

This minimizes the build up of impurities due to membrane creep (the small amount of impure water that is a characteristic of the membrane at the onset of pure water production).

All wetted components are constructed of inert and saltwater safe materials. Power is provided by a plug-in 24 volt AC (UL listed and CSA approved) transformer. The single reservoir model comes with the controller, which includes a switched 24 volts AC outlet for controlling a booster pump or other 24 volt AC operated devices, compression fittings, and 5 feet of tubing for remote mounting of the sensor.

SpectraPure Multiple Tank Liquid Replenishers (LLC-M) are the most advanced means of controlling liquid levels on single or multiple reservoirs and are ideal for replenishing evaporated water in aquariums or liquids in other constant level containers. A sensitive air pressure switch opens a solenoid valve when the liquid level drops approximately 1" and closes it when the liquid level rises back to its original level.

Research at shows that the Multiple Tank Liquid Replenisher provides a significant advantage over conventional float and back-pressure activated automatic shut-off valves by maximizing the duration of membrane operation. This minimizes the build up of impurities due to membrane creep (the small amount of impure water that is a characteristic of the membrane at the onset of pure water production).

All wetted components are constructed of inert and saltwater safe materials. Power is provided by a plug-in 24 volt AC (UL listed and CSA approved) transformer.

The multiple reservoir model comes with a unit which includes a switched 24 volt AC outlet for controlling a booster pump or other 24 volt AC operated devices, compression fittings, 5 feet of tubing for remote mounting of the sensor, a Turbo Bladder, auto shutoff valve, ball valve, check valves and fittings, and one float valve for one additional reservoir.

The system may be expanded to include more reservoirs by adding the optional Float Kit. For additional overflow protection, a secondary mechanical float is also included with every Multiple Tank Liquid Replenisher.
