## Description

desertcart.com: Frizzlife MWT3 Pressure Mini Water Tank for PD400, PD500, PD600, PX500, PX500-A, 0.13 Gallon Small Pressuized Storage Water Tank for Tankless Reverse Osmosis System G2, P600,G3, with 1/4" Ball Valve : Everything Else

Review: 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.
Review: 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
*by E***B on August 19, 2022*

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.
