Review: exactly as advertised, works great - exactly as advertised, works great. Complete kit ready to install, if you’re looking to for a way to periodically fill your auto top off fresh water system this is a good setup. For best efficiency you want to run your RODI for a long time, instead of short bursts. Let the ATO tank get down to 1/4 full then turn on your RO/DI and walk away. This gives peace of mind your ATO tank won’t over flow. When its done turn off the RO/DI feed.
Review: Works exactly as planned - I use this in combination with an RO system and 100-gallon stock tank as a water reservoir for my aquariums when I need to do a water change. This float valve shuts off the RO system when the stock tank is full. This set is nice because it has everything I needed to have the auto-shutoff system and the components seem solid. Very pleased with the outcome.
