Backflow Services

Backflow prevention is used to protect water supplies against contamination or pollution due to backflow. When pressure fails or is reduced, as happens when water mains burst, pipes freeze or there is unexpectedly high demand on the water system, the reduced pressure in the pipe can allow contaminated water from the ground, storage or other sources to be drawn up into the system.

Most municipal codes will require the installation of a backflow prevention device at each cross-connection point found within the plumbing systems of apartments, condominiums, food establishments, and most public and commercial places. The type of backflow preventer required will be in line with the degree of hazard present on the premises. Backflow testing require that valves must be inspected annually to ensure proper operation and to keep your property in compliance with the local code. Your fresh water supply is subject to interruption and your business may be fined if backflow testing isn’t completed in time.

At Flow Plumbing & Drain we can perform annual backflow testing, repairs, installation and backflow certification of all types of prevention devices. Your technician will handle all necessary paperwork relating to your annual inspection,and we will remind you when your next annual backflow testing is due so your property remains in good standing with the local water authority.

Video Pipe Inspection

Our video camera line is one of the most powerful technologies in Flow’s toolbox. It eliminates all the guesswork – saving you time and money. Our video camera line inspection will quickly identify all types of problems, like root intrusion, or pipes that are misaligned, broken, punctured, off-grade or corroded wherever they are.

We recommend that a video camera inspected be done if you experience repeated emergency drain and sewer line backups or clogs or suspect major damage to the pipes themselves. The camera can also identify grease buildup, leaks and obstructions. It can locate lost valuables and even animals that have become trapped.

Real-time video image transmission allows us to determine the condition of the inside of the pipe and understand any existing or potential problems and those images can be saved in Flow Plumbing & Drain’s permanent records.

Common Problems:

Sump Pump

A sump pump is the last line of defense when it comes to flood prevention so it is important to make sure your sump pump is always operating properly. Heavy rains, storm drain backups and broken pipes can potentially cause serious damage to your commercial property and its contents, as well as safety issues for the building’s inhabitants. Triggered by a float switch, a sump pump turns on when the water reaches a pre-determined level and it then removes the water by pumping it to an approved area.

Sump pumps are generally installed in the lowest point of the building. Hotels, apartment buildings and other commercial properties may have elevator sumps to prevent flooding in elevator shafts. Flow Plumbing & Drain are the experts to call when your existing sump pump malfunctions or is in need of replacement. We will provide routine maintenance, testing, repairs and inspections for all types of industrial and commercial sump pumps.
