As a homeowner, maintaining a lush and healthy lawn is probably high on your list of priorities. However, one of the most frustrating issues with lawn irrigation systems is low-head drainage. This occurs when water in the lines flows to the lowest point unless stopped, leading to sprinklers at the low point dribbling after the valve closes. This can cause puddling around your lawn and even lead to wasted water and higher bills. Thankfully, there's a solution: the sprinkler drain check valve.
What is a Sprinkler Drain Check Valve?
A sprinkler drain check valve is a device that prevents water from flowing out of the lowest sprinkler heads after the valve closes, which in turn prevents puddling and damage to your lawn. Essentially, it acts as a one-way valve, allowing water to flow out of the sprinkler head when it is open but preventing it from flowing back out when it's closed. This ensures that your lawn is consistently watered without excess water building up in low points.
Why Install a Sprinkler Drain Check Valve?
If you're experiencing low-head drainage, installing a sprinkler drain check valve can help prevent a range of issues from arising. By preventing water from flowing out of the lowest sprinkler heads, a check valve will prevent excess water from accumulating and damaging your lawn, ultimately saving you time and money in the long run.
Additionally, installing a sprinkler drain check valve can help to save water, reducing water consumption and lowering your bills. By preventing water from building up in low points, less water is wasted and more is absorbed into the ground where it's needed most.
How to Install a Sprinkler Drain Check Valve
Installing a sprinkler drain check valve is a relatively easy process that can be done in just a few simple steps.
Step 1: Turn off the Water
Before you begin installation, turn off the water supply to your irrigation system. This will prevent water from flowing through the lines while you work.
Step 2: Locate the Low Point
Next, locate the lowest sprinkler head in each zone of your irrigation system. This is where the check valve will need to be installed.
Step 3: Cut the Pipe
Cut the pipe about six inches above the lowest sprinkler head. Be sure to use a pipe cutter rather than a saw to ensure a clean, even cut.
Step 4: Install the Check Valve
Insert the check valve into the cut pipe with the arrow pointing in the direction of water flow. Tighten the connection with a wrench to ensure a secure fit.
Step 5: Replace the Sprinkler Head
Reattach the sprinkler head to the check valve and turn the water back on. Check to make sure there are no leaks before resuming use of your irrigation system.
Conclusion
If you're experiencing low-head drainage in your lawn irrigation system, installing a sprinkler drain check valve is a simple and effective solution. By preventing excess water from accumulating and damaging your lawn, a check valve can save you time and money, while also helping to conserve water. With just a few simple steps, you can install a check valve and enjoy a healthier, greener lawn.
