About Backwater Valves

How Does Backwater Valve Work?

The backwater valve is a preventive device against backwater flow incidents. The sewer getting filled up could cause a backwater flow. It can also be caused by a clog in the city’s sewer system which may cause wastewater to flow back to the supplying homes and commercial buildings. The backwater valve is designed to create a gate of sorts which prevents against sewer water flowing back into your house or commercial area. This backwater valve needs to be installed by Aqua Rescue, as we’re currently the number one Plumber Toronto business. Contact us today, and we’ll be there to rescue you from the sewer overflow in no time at all.


A backwater valve is designed with a built in drainage slope which makes sure that the wastewater from your building actually goes into the sewer. Then in the event of a backwater flow, the gate which raises and relaxes with the help of a floatation mechanism fixed on either side closes up your sewer main. This gate is set right in front of your main wastewater pipe and closes up to ensure no wastewater comes back into your building.

Where to Install a Backwater Valve?

Types of Backwater Valves

Backwater valves have different types with little peculiar features with the same purpose, keeping wastewater from your home and commercial building. There are three backwater valve devices, and these devices need to be installed by the best pros in the Plumber Toronto business, Aqua Rescue.


  • Sewer Check Valve - the sewer check valve is the most original design of the backwater valves and is also one of the most pocket-friendly to purchase among the three. The sewer backflow is easily trapped by the sewer check valve and the valve gradually relaxes to release the water used in your home during the emergency backflow out into the main line. The sewer check valve can be easily maintained and needs only to be maintained once annually.

  • Automatic Flood Gate Valve - an automatic flood gate valve is what your home and commercial building needs if you want full protection from the effects of a backwater flow incident. The valve is fitted with an automatic stainless steel plate which seals the sewer out main of your building completely from any backwater flow. The sewer backflow protection device also releases wastewater that was used in your building after the sewer waters start receding to the municipality/city system. This device is also easy to maintain.

  • Manual Sewer Gate Valve - as the name already suggests, the manual sewer gate valve has to be opened and closed by hand and is not suitable for your home and commercial building if you intend to be away for a long while. The manual sewer gate valve has a compartment which you can use to lift the plate which protects your home from being flooded by wastewater. This helps to limit the damages which may have occurred on your property if there wasn’t any safeguard system installed.

  • Other Preventive Devices - apart from backflow valves, there are other measures which can be adopted to prevent a backflow from causing damage to homes and commercial buildings. An air gap is a space which is kept vertically preventing any back flow of wastewater into the building. They are mostly used as preventive measures in the installation of plumbing works.


Also, a backflow preventer can be installed in an area where there is no space for the air gap preventive measure. The backflow preventer is used to provide an additional shutoff for the main out supply of the home or commercial building. If you need these preventive devices installed properly, contact the best in the Toronto Plumbing business.


A backflow valve needs to be installed in a place where there is a high probability of wastewater backflow. It is also installed in areas where the regulations of the city make it compulsory. This mechanism isn’t built to cause harm, and you can install it at any location you desire protection from backwater flow incidents.


A backwater valve can also be installed in residential areas where the buildings are low-lying. Along with other safety measures for such residential areas, the backwater valve will help your building from seeing slightly sloped drainage systems from flowing back into your home in the event of an overflow. Backwater valves provide you a whole lot of security from disease and damage to your property, and the upside to installing a backwater valve is that you have to maintain it once a year, or immediately after the sewer wastewater recedes into the main  sewer system.


The backflow valve is designed to save your home from being an artificial pool. Sewer backflows can be caused by problems with the city sewer system, and these problems are effectively managed by the available prevention devices. These devices have simple mechanisms which do you a whole lot of good in the event of a backwater flow from the city’s main line which runs through your area. Make sure that you maintain your backwater flow valve and other preventive devices as this makes sure the devices work properly in the vent of a sewer mishap. The sewer protection systems we have listed here can be properly installed by the professionals we have at Aqua Rescue, and we will make sure you have the best possible service in the Toronto Plumbing business.

I’ve worked with several plumbers before but was thoroughly impressed with the way Igor diagnosed and dealt with the issues I was having. After about 5 minutes he was able to identify the problem and handled everything with the utmost attention to detail. He is very knowledgeable and thorough, and made sure I won’t have any problems in the future. 5/5 stars, I’d give more if I could

Usually to book plumbing excavation work it takes several weeks. Aqua rescue came within 3 days brining 2 heave machines for the dig. They excavated our main drain, replaced and backfilled everything within 2 full days. The prices are also pretty good
