How or where can I get one?
Many use a 5 gallon bucket…
Check with Kenton. Here’s something from his site:
MEASURING WATER FLOW
Determining the flow rates of faucets and showerheads is accomplished by holding a specially marked container beneath a plumbing fixture for a specific length of time, then reading the water level against markings on the container.
This Water-flow Measuring Bag is held under a plumbing fixture for 5 secondsUsing flow-limiters at showerheads and faucets can save many gallons of water over the course of a year in addition to reducing hot water heating costs. They’re available in a variety of flow rates- .5, 1.0, 2.0 and 2.5 gallons per minute (gpm).
