Sprinkler installation questions
Do you design the system or just install it?
Both. We produce the NFPA 13 hydraulic design and stamped drawings, handle permitting, and install the system with our own licensed technicians.
What is the difference between wet, dry, and pre-action?
Wet systems hold water in the pipe and are the most common. Dry and pre-action systems keep water out of the pipe until needed, for freezers, unheated spaces, or areas where accidental discharge would be costly. We recommend the right one for your space.
Can you add sprinklers for a tenant build-out?
Yes. Renovations and subdivided spaces often need new or modified coverage. We design and install to the new layout.
Do you handle the backflow and water connection?
Yes. The installation includes backflow prevention and the fire department connection, coordinated with your water authority.
Do you also do the annual inspections?
Yes. We inspect and test to NFPA 25 and keep you on a compliance schedule, so one company handles design, install, and ongoing testing.
Are you licensed for fire sprinkler work in Florida?
Yes. Group One holds Florida fire protection license FPC24-000188.
