Why is your hunter PGP sprinkler head leaking?
Firstly, the hunter PGP sprinkler head leaking is due to low head drainage. Secondly, it happens due to the issues in pipes. Broken pipes have a significant effect on this issue, following with the main and lateral lines. Finally, the faulty valve has a negative impact on the sprinkler causing it to leak.
We know this isn’t enough info to help you out. That’s why we have mentioned the reasons and solutions in detail.
Sounds like exactly what you’re looking for right now? If so, let’s get started!
3 Main Reasons & Solutions for Sprinkler Head Leaking
A sprinkler head leaking might not be common. But it’s nothing serious if amended properly. Your sprinkler head might be leaking mainly for these three reasons-
Low Head Drainage
This is the most common reason for the leaking. The lowest head on a zone allows water to flow from the lateral pipework. Water also flows out of your sprinkler along with that. This is known as low head drainage.
We recommend contacting an expert team to fix this problem. You may also try to fix the issue yourself. For that, install drain check valves or adjust your sprinkler.
Seems difficult? Don’t worry! There’s always an expert team to assist you if you’re unable to do it.
Wet areas in your landscape are frequently caused by broken pipes. There are mainly two kinds of water lines that can break in the sprinkler. One is the main one and the other is a lateral line.
The lateral lines feed water to each zone. These are also under pressure with the sprinkler turned on. When it breaks, water starts flowing out of it drastically.
Both main and lateral line breaks due to erosion and over-watering. Moreover, there might be a sound. You may hear water running in the pipe because of broken pipes. This is one way to detect the cause.
Even if there is a break in the lateral line, you can still operate your sprinkler. Switch off the zone in which there is a break. Do this so you can prevent more damage to the landscape.
Now, we’d like to help you out by suggesting two of the best pipes around you:
These are the pipes that can be used in the long term with great sustainability.
Line breaks must be repaired by professionals. They will ensure that impurities such as dirt do not enter the line while they are being repaired. Such impurities have the potential to permanently clog or damage your sprinkler.
Defect in Valve
Each sprinkler valve functions similarly to a faucet, shutting off and on water flow. They can leak, just like any other faucet in your house.
A leaking valve is usually caused by a clog in the valve’s operating mechanism. A broken valve might also be the clog of this issue.
Water will keep flowing out of your sprinkler long after you’ve turned it off. This makes leaky valves easy to notice. But this type of leak could be a sign of low-head drainage as well.
Moreover, you may also have water pressure regulator issues due to defects in the valve.
As a fix, you can just rebuild a sprinkler valve by following a few steps.
Firstly, turn off the sprinkler system’s water supply. You have to do this to prevent getting anything inside the opened valve. Clear the area around it. Turn the solenoid counterclockwise to remove it from the valve body and set it aside.
Solenoid uses electrical impulses from the irrigation controller. This opens and closes each valve to allow water to travel through the system.
Now, the screws that keep the bonnet in place must be removed. Remove the bonnet, spring, and diaphragm gently. Note their positions so you can reinstall the valve in the same manner.
Look for damages or any tears in your diaphragm. Even a little damage can prevent it from stopping the water flow.
Examine the inside of the valve Look for small rocks or sand that could block the diaphragm’s seal. Replace the diaphragm with a new one if it is damaged. Make sure the diaphragm is in the same place it was previously.
Place the spring and bonnet to their previous and original positions. Get the solenoid back to its original position by twisting it clockwise. Do it until it is hand-tight or snaps into place.
Reconnect the water supply carefully at first. The valve shouldn’t be harmed by the pressure. Then check for leaks in the valve. Make sure that the valve works properly by turning it on and off. Ascertain that it doesn’t have any air admittance valve issues.
These are the main issues with the sprinkler head leaking. Following the steps mentioned above would be enough to resolve the issue.
Question: Where do I place a sprinkler valve?
Answer: The valves should be installed in valve boxes dug into the ground. These are frequently apparent. A single valve box is commonly found near the irrigation pipes. The irrigation pipes enter the ground from the water source in tiny yards.
Question: Is there any tool through which water leak can be detected?
Answer: Professional sound detection equipment is the most effective instrument for detecting water leaks. A highly competent expert will be able to listen to the sound of running water.
Question: Where can I place a water leak detector?
Answer: Simply place the sensor behind or beneath any device that uses water. You can also invest in a more complex water shut-off system. It will switch off the water as soon as a leak is detected. It connects straight to your valves. It also protects you from damage before you even notice a leak.
