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. ## Features - [Innovative Solution for Tankless RO systems] The tiny water storage tank is specifically designed to effectively solve the inherit drawbacks of tankless RO systems: a) occasional pulsing of the system caused by unstable water pressure, especially when it is connected to a refrigerator or long distance point of use. b) initial time lag of water output of tankless reverse osmosis system. - [Super Easy to Install: Following clear user manual, the mini water tank is super easy to be installed with 1/4” quick connect design.

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 *by G***N on July 21, 2021* 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. ## Frequently Bought Together - 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 - Frizzlife IMC-1 Ice Maker Fridge Water Line Installation Kit Fits for 1/4” & 3/8” Connect Water Filtration System and Reverse Osmosis System - Frizzlife RO Reverse Osmosis Water Filtration System - 600 GPD High Flow, Tankless, Reduce TDS, Compact, Alkaline Mineral PH, 1.5:1 Drain Ratio, USA Tech Support, PD600-TAM3 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/280310288-mwt3-pressure-mini-water-tank-for-pd400-pd500-pd600-px500](https://www.desertcart.vu/products/280310288-mwt3-pressure-mini-water-tank-for-pd400-pd500-pd600-px500) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
