Lastly, to check the water pressure, you’ll need to use a pressure gauge. TIP: Make sure there is no other water running in your home when you are testing the flow rate. For example, if you can fill two 5-gallon buckets in 1 minute, that means your home is delivering about 10 gallons per minute (gpm). Get a 5-gallon bucket or two, and use an outdoor hose spigot to time how quickly the bucket fills. The first step in fixing your water pressure/flow rate issues is to have a good understanding of the current data. Check Your Current Water Pressure and Flow Rate Here are 4 things you can do that may help! 1. There are multiple reasons that could explain why you are experiencing low water pressure. Why Does My House Have Low Water Pressure? This can often lead to lower “water pressure” because the flow rate simply can’t keep up.įlow rate is determined by the pipe diameter, water supply, friction-loss, and other factors. So if there is a shower running that uses 2 gpm, the washing machine which uses 3 gpm is running, and the kitchen sink is running at 3 gpm, which means 8 of 12 gallons are currently being used. Water Flow Rate is how much volume of water is being delivered in a certain amount of time – most often calculated at gallons per minute, or gpm.įor example, a house with a flow rate of 12 gpm means that the 12 gallons of water per minute can be provided in total. Here’s the catch when it comes to water pressure, in some cases it’s not actually water pressure that is the issue, but rather flow rate. “Good” water pressure in a home is usually around 50 psi to 70 psi.įun Fact: Water utilities are generally only required to provide above 20 psi at the meter, which in many cases is 20 feet or more away from the home. For example, when water is at the pressure of 60 psi, that means the water is applying 60 pounds of force per square inch of surface it contacts. This force is measured by the unit PSI (pounds per square inch). This is what allows water to move from one place to another at an accelerated rate. Water pressure is the force at which water is being applied – generally against pipe or fittings in a plumbing system.
