Here are some of the reasons why you should invest in a sprinkler.

 

1. Water waste reduction

Unlike popular belief, using a sprinkler system for your garden or yard can actually support efficient water use. Smart sprinklers give your lawn the right amount of water, reducing instances of runoffs and over-watering.

 

Moreover, features like automatic timers and rains sensors further enhance its efficiency. Thus, sprinklers can help you lower your household water waste.

 

2. Convenience

Watering your lawn manually can be a relaxing exercise, but then there are those days when you are just not in the mood! Or maybe you have always wished for a lush yard but have no time to maintain one.

 

A sprinkler system can be a lifesaver if you can relate to any of these issues! No need to make time in your schedule for watering your plants. Your sprinkler system has got you covered.

 

If you are away from your home a lot and have no one to look after your plants, investing in a smart sprinkler system is a great idea.

 

3. Saves time and money

Hand-watering your yard can be time-consuming. This may seem like an unnecessary burden when you are already running short of time to do other, more important tasks.

 

A sprinkler system can help you make sure your lawn or yard gets the right amount of water at the right time and frequency without any hassle.

 

Although the installation cost of a sprinkler system may seem high, it can help you save money on your utility bill in the long run. Sprinklers will only use as much water as needed, something that you cannot be too sure of when watering your garden manually.

 

Plus, the sprinklers will make sure none of your plants (that you have invested in) dies due to dry conditions.

 

4. Key to a healthy garden

Lush and healthy yards and gardens can add to the appeal of not only your house but the entire neighborhood. A sprinkler system will make sure that no plant in your lawn dies due to lack of water. These devices are a boon for areas that do not receive much rainfall.

FAQs To Clear Your Doubts

Q. Why won’t my sprinklers turn off?

A. This may happen due to a fault in the main water supply valve. The valve can be partially open, broken, or debris and dirt might be stuck inside it.

 

Another reason can be an issue with the control system of the sprinklers. Or maybe there are problems with other control panel parts, like the sprinkler presets or the controller transformer.

 

Trapped air can also cause the valve diaphragm to malfunction and get stuck in an open position.

 

If you have a smart sprinklers system, make sure to check the settings, especially the timer box. If that’s not what is causing the problem, this may be happening due to mechanical failure.

 

Another reason sprinklers may not turn off is because the internal screw and levers around the main water valve are stuck.

 

Q. Is it OK to cap off a sprinkler head?

A. If the sprinkler heads are too close together, you may want to close a head or two to prevent overwatering the area. This solution also comes in handy when you feel a specific area in the lawn does not need too much watering.

 

It is believed that capping can damage the pipe if you are in a freezing climate. If a pipe is capped when you are blowing out the system in the fall, that section may fill with water, which in turn will freeze and crack the PVC.

 

Hence, you may have to uncap the head before the blow-out. However, this may not be entirely true. With the right way how to shut off a sprinkler head & capping it off the head is unlikely to cause any damage, whether it is located at the end of the line or not.

 

In case the head is at the end of the line, the air will blow a sufficient amount of water out of the lines so that it does not harm the pipe even if it freezes.

 

On the other hand, if the sprinkler head is not at the end of the line, it doesn’t matter because the water will blow right past it.
