Backflow Plumbing ServicesBackflow Plumbing Services has been described as “the unwanted reversal of flow in a potable water system”. There are two types of backflow, back siphonage and back pressure. Back siphonage is “backflow caused by a negative pressure on the supply side”. Back pressure is “backflow caused by a greater pressure in a non-potable system than what you are supplying to that system”. Griffiths Plumbing offers a wide range of backflow services including: building surveys, testing and installation. Our mechanics are licensed plumbers with full O.W.W.A. certifications. Our company is also registered on the majority of most municipalities’ backflow program sites. We can implement all of your backflow needs from obtaining the permits, installation, conducting the necessary inspections and completing the paperwork to satisfy the appropriate municipality by-laws.
