How to choose flow rate by water quality
Flow rate is the first number to settle. It decides whether a model can keep up with your customers' daily use.
Start with the feed water
Ask for the feed-water quality of the target market — hardness and total dissolved solids are the usual starting points. If you need ultra-high-purity water, send your feed-water analysis first — the same applies on the OEM / ODM page.
Match capacity to demand
A countertop model such as RP-C09 is rated 50 / 75 / 100 GPD. A countertop dispenser such as RP-C04 produces 30 L/h. A high-capacity under-sink model such as RP-U03 is rated 1000 / 1200 / 1600 GPD. Choose the capacity band that fits the household or office — not the largest number on the page.
