## Description

Frizzlife mini tank for reverse osmosis system

Review: Kind of interesting it did boost the discharge at the tap for maybe six ounces and then the pump kicks in so the pressure drops off. Then when you shut off the tap the pump runs to fill up the tank. And as a bonus the pump doesn’t kick in every time the ice maker calls for water. Ten minute install
Review: Un osmoseur inverse à débit direct (sans réservoir) pose problème lors de la connexion au distributeur d'eau d'un frigo américain. Ce montage est explicitement déconseillé par les fabricants. Ce petit dispositif régularise la pression et évite tout problème de débit. Il ne coûte pas moins cher qu'un réservoir plus important. Je préfère cette approche qui permet d'éviter le stockage prolongé d'eau osmosée (donc évidemment sans chlore). Ici le réservoir se vide pratiquement à chaque utilisation. En outre il est minuscule (1/2 litre environ). Le raccordement est très simple et tout le nécessaire est fourni. A la livraison la pression (à mesurer à vide) était de 6 PSI, il convient de conserver une pression comprise entre 6 et 9 PSI. Une petite pompe à vélo convient largement mais un outil précis de mesure de la pression est indispensable. Si vous n'en disposez pas, laissez l'appareil tel quel.

*by T***L on 9 January 2025*

its compact and does what it says. larger tanks from ispring are cheaper or at least similar price. however i don't like warm water coming form larger storage tanks. this solves that issue. not much water to store so you will get fresh cold water sooner then larger tanks. its certified plastic so no health issues in near future . all tanks have plastic. connects easily . works for about 200ml before the ro motor kicks in.
