Works great
Worked great as an accumulator for a diy RO booster pump, smoothes out the pulsations. Precharged air to 50psi as the operating psi is 65. Bladder and tank held up to 85 psi working pressure. Pump was the weak link and leaked over 70psi.

It works as advertised
We purchased the mini water tank to use with our PD600 because our system was pulsing and noisy anytime we got water from our fridge (or our fridge made ice). The tank was easy to install and completely eliminated the pulsing. We get the best water pressure on our fridge that we have ever gotten. A side benefit is that the mini tank has also eliminated the 1 second pause at the faucet near our sink. We wondered if this would really make a difference, but we are pleased to discover that it did.

Adds pressure and reduces lag
Have this as part of RO configuration with the Frizzlife PD-500. I have the tank feeding the faucet and a refrigerator. Works great helps get the RO over the longer line to the refrigerator. The instructions are not very detailed - it essentially says put the tank and its connectors together. Just be careful to ensure the washer is in the connector that fits on top of the tank. I hurried to get it put together and did not put the plastic washer in - not surprising, it leaked. Went back to the package and found the washer. Simple fix.

Reduce water flow delay for tankless RO system👍
Most RO tankless water filter systems have a 2 to 3 seconds flow delay after you turn on the faucet. This can be very annoying. Frizzlife MWT3 mini air tank solves the problem and provides instant water flow. Installation is quite easy, and Frizzlife has good customer support. MWT3 works with most tankless RO systems, and the air tank has been working well with my 600 GPD system.

Seems to be working
I ordered this with the Frizzlife PX600 water filter. Installation was simple and all connections are included. The process involves inserting the device in between the filter and faucet to “catch” the water and save it for when you need it. Since I did not use the filter without this device initially I cannot definitively say if it speeds up the water flow. I purchased based on the reviews. The water flow is still slow whencompared to the water faucet. What I can say is that is has substantial weight and does not feel cheap. It is of very high quality and I have no doubt it will last a long time.

Doesn’t last long before losing pressure
I’ve had mine for about two years and suddenly it lost pressure. I read about how RO tanks can be recharged with air using bicycle pump but the one I had could not be refilled. No air would go in at all. I feel like this thing should have lasted at least 5 years before replacing. Fortunately Frizzlife support is willing to send a replacement at no charge.

Super easy install and effective pressure
I have a tankless RO system and when I connected it to my fridge, I got the on-off-on-off toggling of the RO Tank's pump due to the pressure fluctuations in the fridge line. After doing some research, I found that this is what I needed. I'm happy to report that this immediately resolved my issue! Would definitely recommend this for anyone encountering the same issue.

Just what I needed
I needed a small accumulator tank for a coffee machine that was plumbed in with too small of a diameter water line. This worked perfectly as it is small enough to not get in the way, yet held the right amount of water to prevent cavitation. Wish it was a little cheaper, but given there are no competitively sized accumulator tanks, I get it.

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

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.

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.

It’s ok 👍

J’ai acheté pour l’installer avec l osmoseur de la même marque. J’ai relié avec mon frigo américain et sa fonctionne sans soucis . Cela permet de remplir un verre très rapidement sans avoir une grosse cuve avec de l’eau stagnante. Il se re rempli en seulement quelques secondes.
