We provide this service for all brand name systems including, but not limited to, Ansul, Pyro-Chem, Pro-Tex II, Kitchen Knight, Range Guard, Buckeye, and Kidde.  We will be happy to provide a quote for required semi-annual system inspection packages, new installation and/or system hydro tests.

Carbon dioxide or CO2 is a colorless, odorless, non-conductive gas that suppresses fire without leaving behind any residues after discharge, thus avoiding damage to sensitive equipment.

With no agent clean up, there is less downtime after an incident. When properly designed, the carbon dioxide system will suppress fire in Class A, B, and C hazards by displacing the air containing oxygen that supports combustion.

Our specialist can provide bids/quotes, installation, upgrades, inspections and service for all CO2 engineered systems, including hand held and wheel unit extinguishers.

Double D Piping has several certified backflow prevention technicians to perform backflow testing on domestic, irrigation, and wet and dry sprinkler system backflows.

Backflow preventers (a.k.a. cross connections) are mechanical plumbing devices used to prevent the undesirable reversal of the flow of water from its intended direction in any pipeline or plumbing system. Backflow is dangerous because it can allow drinking water in plumbing systems to become contaminated and unusable.

Per the AWWA, domestic and irrigation backflows must be tested annually; and per NFPA 13, wet fire sprinkler system backflows must be tested annually and dry sprinkler system backflows must be tested semiannually.
