Frequently Asked Questions
What type of pipe is used for fire lines?
We typically install ductile iron or high-strength PVC piping designed for underground fire protection systems and rated for required pressures.
Do I need a backflow device on my fire line?
Yes. Backflow prevention is required to prevent contamination of the potable water supply. Our certified technicians handle installation, testing, and maintenance.
Can you test my existing fire line system?
Absolutely. We provide flushing, pressure testing, flow measurement, and backflow testing to ensure full compliance.
How do I know if my fire line needs repair?
Signs include reduced water pressure, visible leaks, corroded fittings, or failed inspection results. We can assess and recommend necessary repairs.
Do you coordinate with local utilities and fire departments?
Yes. We handle all necessary permitting, inspections, and tie-in scheduling with water districts and fire safety officials.
