Maintain Your Underground Sprinkler System

Well-maintained landscaping adds to the beauty of your property, and it order to keep those plants and grass beautiful, you need to keep them watered. If your home has an underground sprinkler system, you'll want to make sure it's working properly.

How to maintain your underground sprinkler system.

What Needs To Be Done

Your home's underground sprinkler system requires regular maintenance to keep it running optimally.

Why Do It?

There are many reasons your home's underground sprinkler system needs regular maintenance. Here are the primary reasons:

1. Water Conservation
Lack of service can result in unseen leaks that will continue until fixed—not to mention the fact that if the sprinkler heads are not properly adjusted, water will be wasted on areas where it's not needed, like driveways or roads.

2. Ensure Water Falls Where Needed
Regular maintenance will help assure that the water spray is used in an optimal manner. It eliminates dry spots or the overabundance of water in an area.

3. Safety
Your sprinkler heads can be a danger if they are not regularly maintained. Children or others walking in your yard can easily trip on exposed sprinkler heads. Regular maintenance will help ensure that sprinkler heads are kept flush with the ground when not running.
