Do You Need A Backwater Valve?

Installation

Before purchasing a property, it’s advisable to check whether a backwater valve is already installed. If you’re building a new property, you can have a valve installed at a relatively low cost. However, it’s also possible to install a valve in an older building. While retrofitting can be more expensive, it is a worthwhile investment to protect your home or commercial property.

In some cases, you may be eligible for a rebate, so it’s worth checking if this is available in your area. Additionally, installing a backwater valve can be a good long-term investment, as properties at risk of flooding may be less attractive to potential buyers.

How They Work

The valve consists of a small flap that allows water to flow away from your home and ventilates sewer gases. It has flotation devices on either side of the flap, which are designed to lift and close as needed to prevent water or sewage from flowing back into the house.

Retrofitting

If you need to retrofit a valve, you must ensure you have the correct permissions, which can vary depending on your local area. This process involves a contractor cutting a small hole in the concrete floor, accessing the main sewer line, and replacing a portion with a new valve. Once installed, the cover must remain accessible for any future servicing needs.

It’s crucial to hire an experienced plumber, like Handyside, for this work. If the valve is not positioned correctly or improperly installed, there is a significant risk of sewage backing up into your home, which can cause serious damage and pose health risks. Installing the valve helps protect your home from flooding and water damage, offering greater long-term peace of mind.
