Featuring an adjustable, corrosion-resistant float valve and an 8-meter RO tubing setup, it fits a wide range of tank sizes and installation styles.

## Description

Features: √The equipped RO white 1/4 inch OD tube is five meters. Plastic hanger can be applied to the thickest glass of 19mm. When the L bracket is installed reversely, the water level height will be 5-15cm, on the contrary, when the L bracket is installed normal, and the distance between the water surface and the edge of the cylinder will be adjusted in 15-25cm. The reverse installation of L bracket will be more difficult. √The replenishment tank can be recognized as the water adding device installed at the bottom of the tank (After the seawater evaporates every day, the water in upper district will appear). When replenishing the water, the aquarium water adding device will take advantage of the atmospheric pressure or the water pressure to replenish water, and no additional water pump is needed. √If the back filter cylinder cannot be used, there should be no space. Before using the fish tank water adding device, you have to check it to ensure security. The valve should not be opened too much as the heavy pressure will cause the tube lose control. Please choose the device carefully Package includes: √Retractable plastic rack*1 √RO water machine float valve*1 √8 meters 20ft white tube for RO water machine*1 √1/4 inch quick push to connector *4 Precautions √The water replenisher is just an open pipe, and the water source need to be connected to the water pipe, to achieve this, a conversion head, RO machine and water replenishment bucket are needed.

Review: Very Adjustable to achieve optimal water levels with a great bag of connectors - The cost of the quick connects and RO certified tubing alone makes this worth it. (I had to pick up one of those push to connect on-off valves for another project at Home Depot for $12.55, and this set came with one thrown in). I had a similar device fail in the open position once, so I paired this with an auto cutoff Ortis WiFi Power Failure Alarm with Water Level Detection to my RO pump (https://a.co/d/9YxxFE7). However, this one seems less likely to fail as the RO water comes out right over the float joint which should keep it from getting salt build up to jam it.
Review: Worked as described - Hooked up to my ro system to my reservoir and it worked great kept me from flooding my basement. Fits well to a 32 gal trash can or anything similar. You can adjust the float level to an extent.
