Food Establishments Require Grease Interceptors

Grease and cooking oil have great potential to clog drains and pipes. In the home it means that people need to be careful about what they put down the drain, but in a restaurant the potential problems are much greater, and special devices must be employed to contain all the grease and oil. Food establishments are required by Winnipeg city code to install and maintain grease interceptors.

Grease interceptors are required to be installed by a licensed plumber, so this is definitely not a do-it-yourself project. The business owner also owns the pipe from the point of connection to city services, and this area is the responsibility of the business owner to maintain. Maintenance logs have to be kept, and annual inspections are also mandated by city code.

What about restaurants that don’t use grease? Are they required to install an interceptor? The answer is “yes”, because a grease interceptor will also capture cooking oils, which also have great potential for fouling drain pipes. Although there are cases where requirements are waived, this can only be done on an individual basis, and necessitates an on-site inspection and appraisal of your business.

Install and Test a Backflow Prevention Device

A backflow prevention device is required whenever there is potential that cross connections can lead to contamination of the city drinking water supply. There are three basic types of backflow prevention devices: a reduced pressure assembly, a double check valve assembly or a dual check valve assembly.

It requires a plumbing permit to install a prevention device, and these permits are only available to someone who holds a Plumbing Contractor’s License. It is, however, up to individuals to make sure that a device is properly installed, maintained and repaired, tested periodically and retested if any repairs or maintenance are performed on the device.

It is also the responsibility of the owner to ensure that annual inspections are performed by a tester who is licensed by the city. Potential hazards are rated on a scale, and this rating helps determine the type of device that is needed. The greatest hazards are generally related to industrial and commercial facilities, and hospitals and mortuaries. The lowest ratings are for such household devices as flexible showerheads and water softeners, and in places like hair salons and beauty parlors.

Derksen Plumbing & Heating is available to address your needs, from repair and maintenance of an existing system to design and installation of a brand new system.

What are cross connections and backflow?

Both terms, cross connection and backflow, have to do with plumbing situations that can potentially contaminate a pure water source. The City of Winnipeg is vigilant when it comes to protecting public drinking supplies, and the by-laws of the city code are very specific when it comes to system construction and maintenance.

A cross connection is described in the Winnipeg city website as “an actual or potential connection between the drinking water supply and a source of contamination in a plumbing system”. Any connection with this kind of potential must be safeguarded to prevent any incidence of backflow.

Backflow, as the name suggests, is a reverse flow of water back into the city system. There are two ways that this backflow can occur. The first way is known as “back siphonage”, and this can happen if the pressure in the city system drops, which can happen during periods of heavy municipal use, as during firefighting efforts. The other way backflow can be caused is known as “back pressure”, and you get this when the pressure is greater in your system than in the city’s.

Proper devices are necessary to prevent contamination, and Derksen Plumbing & Heating is ready to help you with all your commercial system needs. Give us a call (204-669-4450) or complete our online form and set up an appointment with one of our highly qualified professionals.

Backflow for Businesses: Cross Connections and Backflow

Cross Connections and Backflow Violate the Water Works By-Law of 1973

Potable water is a precious commodity, and one we need to protect. Here, in Winnipeg, we have statutes designed to enforce that protection. The Water Works By-Law contains provisions that ensure that the public drinking water supply will not suffer from the problems associated with cross connections and backflow.

Cross connections occur when a pure drinking source is linked, potentially or actually, to another source that may be contaminated. Backflows are what the name implies, and occur when reverse pressure at the end of a line is either greater than the incoming supply, or hasn’t been checked by a proper device. The possible health hazards are numerous, and the Winnipeg municipal government issues the following statement in the civil code book: “Backflows due to cross connections can cause illness and even death. Contact us if you any questions or concerns about this potentially dangerous situation”.

Property owners are cautioned about proper installation of devices that control backflow, and about the ways cross connections can be avoided.
