💧 Why every basement renovation needs this! During a basement reno, one of the most important things we install is a backflow prevention valve. Toronto’s city water can sometimes push back into older homes, and the last place you want that water ending up is inside your basement. This simple device uses a flap that closes when water tries to flow the wrong way, keeping your drains protected and your basement dry. Small addition, huge peace of mind. | Bigelow Construction
