Increasing the water pressure from a garden hose saves you time and energy when watering lawn and garden areas. Additional pressure allows the spray to go further and more water to come out of the hose end to facilitate quick, efficient watering. If your garden hose has small leaks, which can lower water pressure, it is probably time to purchase a new hose.
Look at the connection between the water hose and outdoor faucet. Ensure the coupling is screwed on straight and tight. Otherwise, you will encounter a spray of water from the faucet connection, causing a reduction in water pressure.
Purchase a garden hose that has a larger diameter than the one you own. A hose that is one-half inch in diameter delivers 9 gallons of water per minute, compared to one with a three-quarter-inch diameter that delivers 23 gallons per minute, according to the Aubuchon Hardware website.
Check the garden hose for any twisting or kinked sections that may be restricting the flow of water and affecting the pressure.
Add a pressure washer to your garden hose if you are using it to clean brick, concrete or the siding on your home. This increases the water pressure substantially, according to the article "Boost Pressure Behind Garden Hose" on the AZ Central website. Read the directions for your model carefully. Using the pressure washer too closely or not for its intended use may damage your home, deck or other property.
