7 Easy Steps to Test Your Well Water Flow Rate

Hello Peter,

Thank you for contacting us through our website.  You wrote:

Ok sir, first of all, you wrote that your flow rate is 1.6 gpm.  That’s really low, where did you get that number from?  You could barely run a shower with a flow rate like that.  If you need to run a test on your flow rate, here are instructions on how to determine flow rate for wells with pressure tanks:

It is easy! 
All you need is a 1 or 5 gallon bucket and a watch or clock! It takes just a few minutes. 

Just follow these steps:

1. Open any hose bib or faucet until well pump turns on.
2. Close hose bib or faucet and let pump fill up pressure tank until well turns off.
3. Using a 1 or 5 gal. bucket, open faucet, collect and measure all water discharged until pump turns on. 
NOTE: You do not have to fill the buckets as fast as you can; simply measure the water.

4. When pump turns on, immediately close faucet and start timing pump cycle in seconds until well shuts off.

5. Divide the number of gallons collected in Step 3 by the number of seconds in Step 4.

6. Multiply the answer from Step 5 by 60.
7. The answer in Step 6 is the average pumping capacity of the pump in gallons per minute (GPM).

Second of all, do you happen to have a well water report that we could refer to?  Ideally, we would need to have the water analysis on hand in order to know what to recommend to you. If you’re interested, here is a link to a test kit that we offer, that you can use to cover the basic mineral content of your water:

Basically, it’s a two-part test kit.  It includes testing at home, on-site, that you would perform yourself for iron, pH, manganese, hydrogen sulfide, etc… and it also includes two sample bottles in a mailer that goes back to use for testing at our lab.  The lab test is quite accurate and gives results for hardness, manganese, iron, TDS, and pH.  Between the home testing and lab results, we should have everything we need to make a great recommendation for you on how to remove that iron and prevent odor and staining problems.
