If you want to water your plants in your garden evenly, then having a sprinkler surely is a good idea. However, things might get a bit complicated if you don’t have high or at least normal water pressure inside these sprinklers.

There’s no doubt that constant low water pressure is quite the problem when it comes to gardening and watering of the plants. That’s why you will need to increase water pressure for sprinklers inside your garden.

And, to do so, we will explain to you exactly how to do it. So, let’s begin. 


How to Increase Water Pressure for Sprinklers

In case you have plenty of sprinklers inside your garden, you might experience a significant loss of water pressure. That’s why you need to take some measures in order to increase it.

Anyhow, follow these few steps and see how to increase water pressure for sprinklers.

Step 1 – Check for Elevation

Possibly the most common mistake people tend to make is that they position the water line a bit below the system of sprinklers. Now, the level of water supply line needs to be at least 1-foot higher than your sprinkler system.

This will ensure that water can easily flow through the pipe and come into the sprinkler. Otherwise, there will be a slow flow of water and therefore, the water pressure will be low.

For every 1-foot level difference between the water line and sprinkler system, the PSI drops by 0.433 points. Simply put, water from the water supply line will not be able to travel fast enough through the pipe and feed sprinklers.

Step 2 – Malfunction of the Water Regulator

In some cases, the problem is located at the water regulator. Namely, the water regulator is equipped on every water line so it can regulate the water pressure.

So, if the water regulator is malfunctioning, then the water pressure will be low. However, it’s not that strange at all to have extremely strong water pressure as well. That can really damage your sprinklers and cause a lot of problems in your garden.

Anyhow, you need to check the water regulator and determine if there are any flaws. The reading on the water regulator will tell you exactly what the level is of water pressure inside the sprinklers. In that light, you will know whether to change it and regulate it yourself.


Step 3 – Head Adjustment

One thing that most people don’t do so often, is to check the sprinklers heads. These head adjustments are also the cause of low water pressure. Sometimes, your water line and water pressure will be just fine, but the problem will be located at the sprinklers head.

Finding a proper head adjustment for your sprinklers is quite important for having good water pressure. However, if you don’t want to change the head of the sprinkler, you can always try to adjust it.

You will need to simply turn the sprinkler head counterclockwise and allow the water to flow through it at a faster speed. This will increase water pressure in your whole sprinkler system and your garden will be properly watered once again.

Step 4 – Head Cleaning

Similar to Step 3, this step requires you to check the sprinkler’s head for nasty build-ups. As we all know, water is full of minerals that can build up inside the pipes and sometimes around the sprinkler’s heads.

Also, there is a high possibility that the sprinkler heads are full of dirt from the garden. This can happen more often than you should suspect. In that light, you will need to check for clogs or dirt build-ups on your sprinkler heads.

If there are possible dirt build-ups around the sprinkler heads, you simply need to clean it with water. It is the best to use a garden hose and rinse the sprinkler heads until they are clean again.

However, if there’s a clog or mineral build-up around the sprinklers head, you will need a stronger solution. You should use baking soda and vinegar mixture to dissolve that build-up and clean the head.

Step 5 – Head Replacement

Sometimes, when the sprinklers are not working properly, the reason might be located at the sprinkler head. This means that sprinkler heads are usually broken or damaged in some manner.

If this is the case with your sprinklers too, then you need to replace all the heads on your sprinkler. This will allow water to flow once again at the normal water pressure through the sprinkler and everything will be fine again.

However, make sure to get the right replacement. Sprinkler heads that are not compatible with your sprinklers are not useful to you at all.


Step 6 – Boost Pump Installation

If everything is flawless when it comes to your sprinklers heads, the problem might be somewhere else. In some cases, you can locate the problem at the main water line. This means that the water pressure is low because of the main water line.

However, you don’t need to worry about that. You can simply install the boost pump and ensure that the water pressure will be great once again. Your garden will soon be watered properly and you will have nothing to worry about.

Anyway, when choosing a boost pump, make sure to look out for the PSI level and the number of sprinklers you have in your garden. Sometimes, there will be a huge difference in the water pressure depending on the boost pump you choose.

Conclusion: Increasing Sprinkler Water Pressure

It is quite important to have good water pressure inside your sprinkler system. With low water pressure, your sprinklers won’t be able to do their job and your garden will not be properly watered.

And, as we can see, increasing water pressure inside the sprinkler system is not that hard after all. All you have to do is to follow these few steps and make sure to check every possible sign of low water pressure.
