Ensuring you have the right water pressure from your outdoor spigot enhances its functionality, making it easier to do things like water your plants, clean, and much more. Learning how to increase water pressure on an outdoor spigot will help you gain a healthy flow of water for all of your outdoor projects. Let’s dig into the details of how to increase the water pressure in your outdoor spigot yourself.

Prepping to Increase the Water Pressure in an Outdoor Spigot

Before increasing the water pressure in your outdoor spigot, investigate the cause of weak water pressure. Start by taking a look at your hose. Unscrew it and run the water out of your outdoor spigot. If you notice the water flow improving, replace your garden hose. However, if you notice poor water flow after removing the hose, you’ll want to follow these steps to first identify the issue and then improve the water pressure.

  1. Check for Leaks

    Along with your garden hose, investigate other areas around your outdoor spigot for signs of leaks. To accomplish this, turn off all indoor and outdoor faucets and any other appliance using water. From here, go to your water meter, which is likely in your home’s basement near the furnace and water heater. If it’s not there, it could be in your utility closet.

    Once you find your water meter, check to see if it’s spinning. A spinning water meter indicates it’s still using water. And with all water-using appliances and faucets shut off, you have a leak somewhere in your water supply line. Follow the water pipes to see if there’s any buildup of water.

  2. Inspect Water Piping

    If the water meter doesn’t spin after shutting everything off, you should still inspect your water pipes. Sometimes, it isn’t leaks that weaken the spigot’s water flow, but a clogged supply line. Inspect your water pipes for signs of aging or corrosion. This often happens more with copper piping—PVC and PEX lines are less susceptible. If you find corrosion or signs of pipe damage, contact your local plumber to come out to inspect and replace the damaged pipes.

  3. Check Your Water Pressure

    If it isn’t the hose or the piping that’s causing low water pressure, then it could be low water pressure emanating from the water main. Therefore, learning how to test water pressure at the hose bib is essential. You can buy a water pressure test gauge at your local hardware store. Make sure to buy one with ¾-inch female hose threads for proper readings.

    Next, locate your outdoor hose bib—this is what you connect your garden hose or sprinkler system to. Screw the gauge onto your outdoor hose bib, ensuring it’s a tight fit. From here, turn on the water to receive a reading. Water pressure gauges read in pounds per square inch. You’ll want a reading around 45 to 55 PSI for a healthy water flow. Anything less than that indicates you’ll need to increase the water pressure. However, you also don’t want it too high, as having a PSI of 70 or more can damage piping.

  4. Dial Up the Water Pressure

    Each home contains a water pressure regulator, allowing you to adjust your water flow. Normally, these are found near your water meter. In cases where the water pressure gauge reads a lower PSI, ramp up the water pressure on the regulator. There’s a screw on the regulator that influences pressure output. Take a screwdriver to turn the screw clockwise to increase the water pressure output. If you’re struggling to find where the regulator is or have concerns about damaging your pipes, consult with a plumber before going through with this step.

  5. Test Your Outdoor Spigot

    After adjusting the regulator's water pressure, return to your outdoor spigot and turn the water on. If you notice a better water flow, your work is done. Next, hook your hose or sprinkler attachment to test it again. If you notice the water flowing from the hose or sprinkler head is where you need it to be, you’re good to go. 

    Meanwhile, if the flow still seems weak, it would be a good time to bring a plumber into the mix. They’re adept at testing different hose bib types, searching for leaks, and finding solutions to problems with your system.

DIY vs. Hiring a Pro

Increasing your water pressure is a great project you can do yourself. It’s not too complicated, time-consuming, or expensive. Learning how to tackle a simple project like this can also prepare you to take on other DIYs in the future. Hiring a pro is certainly another option but along with the convenience comes a high cost. The average cost of hiring a plumber is between $180 and $490.

In order to make sure you are confident about your choice make sure to do your research before starting your project. This would include watching tutorials online and getting advice from anyone you may know who has experience with this type of DIY project. This way you are confident in whatever decision you choose.

Frequently Asked Questions

The average cost of an outdoor water spigot is anywhere from $150 to $500. Spigots come in both brass and plastic, which causes a variation in the price and will determine the average lifespan of the spigot.  It’s important to do a little research on the spigot that you chose in order to get the best price and quality for your project.
