There are several methods we use for sewage backflow prevention, each suited to different types of property and drainage layout. After surveying your property and sewer system, we can implement the most effective sewer backflow preventer for your specific needs, rather than fitting a one-size solution regardless of how your drains are configured. Sewage defence isn’t something most homeowners think about until it becomes a problem, but by then the damage and disruption have often already happened, which is why we recommend having your drainage assessed as part of any wider flood protection plan.
The Flap Valve is a piece of piping fitted onto the used water pipe leading away from a property, and it functions as a straightforward sewer backflow valve. It uses the flap mechanism to allow the normal passage of used water to flow away from the building, but the flap will not allow any overflow water caused by flooded sewage pipes back into the property. This makes it one of the simplest and most effective forms of sewer backup prevention available, since there are no moving parts beyond the flap itself and nothing for a homeowner to operate manually.
It is a 110mm thick pipe with the non-return valve fitted which, once installed, offers a permanent solution protecting properties from sewage and wastewater backflow into toilets and ground floor or basement bathrooms. As a dedicated sewer backflow preventer, it’s designed to work automatically the moment pressure from the sewer system reverses, closing off the route back into your home before any wastewater has the chance to enter.
Backwater non-return valves are used to prevent any back-flow through the sink, dishwasher and shower outlets, and function as a sewer backup prevention valve for individual appliances rather than the whole property. These are available in 32mm, 40mm and 50mm sizes, allowing us to match the valve to the exact outlet it’s protecting rather than fitting an oversized or undersized unit.
If you’ve recently suffered from a flood, ensuring you have the right sewage backflow prevention in place for your appliances is essential for ongoing protection, since a single unprotected outlet can undo the benefit of every other defence fitted elsewhere in the property. By installing a non-return valve, water is unable to travel back inside your property, and you’re protected from any sewage issues you could otherwise face during a flood. Fitting a sewer backflow valve to each vulnerable outlet, rather than relying on one solution for the whole system, gives a more complete and reliable form of sewage defence overall.
Sewage is one of the most unpleasant issues you will have to deal with if you are flooded, and it’s often the part of a flood that causes the most lasting damage to a property’s contents and flooring. Stormguard Floodplan’s Flap Valve is a permanent solution for keeping your home sewage free during a flood, combining reliable sewage backflow prevention with a design built to need no ongoing maintenance once it’s installed. As a trusted sewer backflow preventer, it forms one of the most important layers of any complete sewage defence strategy, working quietly in the background until it’s actually needed.
