How to Increase Water Pressure for Sprinklers

When plants and flowers need watering, and the grass needs sprinkling. Having adequate garden water pressure is vital. To ensure the job gets done quickly and efficiently.

Using a pump from the water source could be a lake or a well. To apply pressure to the water while pumping through the hose pipe. To the sprinklers.

The water builds pressure as it is going. Hence the water can reach up to 33 feet from one sprinkler. 

In case your sprinkler is attached to a tee post. Disassemble the sprinkler by first cutting the hose clamp. It comes apart very easily.

On one of the inside parts, you will find a washer, which has been put there to restrict water flow.

Remove it to get water with a less restrictive flow. Also, remove the clamp that restricts the movement of the water to one side. Instead, let it spray water all around.

In addition to that, loosen the nozzle at the front. On it, you will find another restrictive washer. It falls right out. Then screw the nozzle back and assemble back the sprinkler.

To know your pressure, use a pressure meter on the spigot because there is a difference between the water volume and the pressure coming out of a hose.

GPM means the gallons of water coming in per minute into your home. While the PSI is the overall pressure of the water.

Thus, using a pump and removing the washers that act as restrictors. You are adjusting the water pressure.

When adjusting the water pressure regulator, use a pressure gauge on a regulated source like an interior sink. Do not go above 60 psi.

The GPM is affected by the hose you use. Their length, as well as their diameter, affect the pressure and the flow of water over time.

So, if you use a half-inch hose, you will have difficulty watering in any volume. Five-eighth or three quarters is better.

Keep in mind that valves do impact the GPM. The valves include shut-off and splitters that greatly reduce the water volume.

When using the water connectors, they turn on and turn off. Eliminate the valves.

It is important to understand that you may have stronger water pressure at the front of your house than at the back. One could run through a pressure regulator, and the other isn’t.

In other cases, there could be a slight blockage within the pipework. Leading to the tap or the garden itself. Therefore, clean up the pipes.

Your interior piping can also affect the water pressure, especially its small diameter. Around half an inch will affect the volume of water flowing through the hose.

Always check that there are no leaks or worn-out parts in the hose. A new hose or making repairs to your existing hose. Maybe all that is needed to solve the problem.

Another common mistake that people make affects the water pressure. It is not turning the water valve on fully.

If generally the volume of water coming into your house is low. Consider installing a rainwater harvesting system.

This is collecting rainwater from surfaces such as roofs and flooded areas.

Therefore, you will have lots of volume of water in one place. Hence more water pressure to use in the irrigation of lawns or flower beds.

Finally, increase the water pressure in your sprinklers. Adjust your settings to about 60 PSI. Reduce the number of fittings that you use. Lastly, use a larger diameter hose.
