How to Measure GPM without Using Fancy Devices or Meters

By | May 18, 2018

Every appliance and fixture in your home that dispenses water can be rated based on GPM (gallons per minute) that pass through it. The flow rates vary depending on age and water-efficient design of the fixture. Now we will talking about what is GPM.

If you want to control your water bill costs, you will want to know and control these GPM rates. If you know the control of GPM rates, then you can easily control your water bill costs. Butthe problem is that only a few homeowners have a sense of the amount of water they are using in their homes.

The good thing is that you can test out the GPM of your facet easily without using fancy devices or meters.

How to test GMP without using any devices or meters?

In this post, we have covered the two ways that you can use to do this:

One gallon method

The one gallon method is basically the more reliable easier method that you can determine GPM at home. Follow these simple steps:

  • Find a one-gallon sized container and place it beneath the faucet.
  • Turn on the faucet at full capacity and start the timer.
  • Stop the timing immediately the water reaches the top of the container.
  • Round up or down the figure to the nearest “5.” That means if the timer is reading 27 seconds, you should round it up to 30 seconds.
  • You will then divide 60 by the number you above. In this case, 60 divided by 30, which is 2.
  • The number you get as a result of the division is the GPM. In our example, the faucet has a GPM of 2.

15 second method

  • Take a large container such as a five-gallon bucket beneath the faucet.
  • Start the stopwatch and run the water from the faucet at full capacity for 15 seconds.
  • Use a gallon-sized container to measure the amount of water, and if necessary, use a conversion tool to convert to gallons and multiply the figure by 4. Generally, the resulting figure should be about 2.2 GPM.

How to reduce water usage

Considering that an average person uses anywhere between 50-100 gallons of water each day, you can reduce that figure significantly:

Use aerators on your faucets

Remove oil toilet and replace it with a modern toilet.

You may also want to remove luxury items such as fountains, hot tubs, swimming pools and garden ponds.

Install a low-flow showerhead

Replace old appliances like dishwashers and cloth washers with an energy star rated appliances.

Repair any links you may have

Be conservative: shut the water off when brushing your teeth, take shorter showers, fill the sink with water when washing dishes rather than running the faucet, and so on.

Conclusion

If you have been asking yourself “what is GPM?” then we believe that you now have a clear picture of what it is. Just to take you briefly through what we have discussed, GPM stands for gallons per minute and it’s a measurement for water and other fluids that pass through a faucet. You can also measure the GPM of your faucet without using fancy devices or meters.
