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.

How Often?

Your underground sprinkler system needs to be maintained on a monthly basis to assure its optimal functionality. You should always check with your own manufacturer's advice about maintenance, but irrigation system manufacturer has these suggestions:

Monthly Once Per Season As Needed
Adjust timer. Clean all sprinkler heads
and filters
Unclog sprinkler heads
Check and adjust sprinkler sprays. Manually operate each valve. Adjust heads to
ground level.

if needed.
Check wire and wirenuts
for damage.
