30-Second Shower H2O Volume Test

"Most Acceptable, Most Cost-Effective & Most Sustainable"

First, you (the business Chief Executive Officer, Owner or Family Member) must test or witness, your current shower tests to determine the output water volume in gallons per minute (gpm) providing truthful answers to requested information to quality for a "free" test unit.

If you have more than one model, test each model.  Even when a shower head is marked 2.5, 2.2, 1.75, 1.5, or 1.25 gpm, it may be as high as six (6) gallons per minute or as low as 2.2 gpm, depending upon the water pressure into the building, the time of day and the number of stories of the building. 

The average additional savings from a shower marked 2.0 - 2.5 gpm, when compared to the 1.5 gpm “Jet-Stream” Showerhead is fifty-five Percent (55%).

How To Test Any Low Flow Shower's Water Volume In 30 Seconds

By K. H. "Skip" Haynes:

  • A 3-gallon bucket (any known size will do) to capture all the shower water.
  • A stopwatch or watch with a second hand and time with the hot and cold valves wide open for maximum water usage for 30 seconds. (If there is uncertainty, repeat the procedure.)  Note!  1.5 gallons in 30 seconds is 3.0 gpm. 
  • You may want to have someone to assist you to hold the bucket or monitor the time.

For Proof Of Savings, here's what to do:

1Before installing the water & energy efficient, high-pressure, 1.5 gpm "Jet-Stream" Showerhead®, turn on the current shower head and adjust hot and cold-water valves all the way open for the maximum flow rate of the current shower and feel the pressure of the shower with your hand.

2Place a bucket, any known size, under the shower and capture all of the water for 30 seconds (see chart below). If uncertain of the results, repeat the test and have a second person use the watch to time the test.

Caution!  When you receive the 1.5 gpm "Jet-Stream" Showerhead, follow the 2-Minute Installation carefully as improper installation directly effects the quality of the shower!  It is important that the swivel angle be in line with the pipe extension, plus or minus 30 degrees when capturing the water from the output.  Do not turn the swivel down more than 30 degrees to capture the water in the bucket!  Move the bucket to the output of the shower head, maintaining the 30 degree angle. 

3After installing the water & energy-efficient, high-pressure, 1.5 gpm "Jet-Stream" Showerhead®, by hand, perform the same test for the same length of time (30 seconds) which shows you the water volume usage savings and see and feel the pressure difference. If there is only half the water, the savings is 50%!
