Standard for Balloon-Type Ball Backwater Valves
Scope:
The balloon-type backwater valve is a fault resistant product that combines three elements:
- a micro-electric water sensor,
- a pneumatic bladder device to seal a sanitary line, and
- a control panel.
When the sensor detects a sewer backwater situation, the control panel inflates the balloon bladder to effectively and quickly seal off the sanitary waste pipe so that the backwater will not flood the basement of a dwelling. This is a retrofit device that can be integrated into the existing sanitary waste piping without the need for extensive excavation of the concrete floors as is needed with traditional-type backwater valves.
