Frequently asked questions
Does Florida require a rain sensor on sprinklers?
Yes. Florida Statutes require an automatic rain shutoff device or soil moisture sensor on new automatic landscape irrigation systems, and most water management districts also set day-of-week watering restrictions.
How long does irrigation system installation take?
2-4 days of work. Permit review and inspection scheduling are usually the largest source of variation.
What changes the price the most?
The largest cost drivers are lot size and number of zones; water source: city meter, reclaimed or well; backflow preventer requirements.
