7. If I have a problem, what should I do?

The Utility Systems Department has a 24-hour service to call at (772) 873-6400. The system is equipped with an alarm system that is generally located in the garage or on the outside of the house on the control panel box. The warning light and an audible alarm should activate as soon as the water level rises above the normal level.

8. What do I do If I hear or see alarm?

When you hear an alarm, or your neighbor is not at home and you hear theirs, you can silence the audio portion of the alarm by pressing the red light button located at the front center of the control panel box. You should then call (772) 873-6400 for service. The Utility Systems Department has a 24-hour service to answer your call.

You may also have a problem if you notice your toilets are sluggish when flushed and water drains slower than normal. You should make every attempt to conserve water until your service call is answered.

For any problem or questions regarding the system, please call the Utility Systems Department at (772) 873-6400.
