Keep basement floors dry during sewer surcharges by giving backups somewhere else to go. The General Wire Flood-Guard? S-4F is a standpipe-style backwater device for 4? floor drains: when the main line backs up, water rises safely in a vertical standpipe instead of onto the floor. The S-4F threads into the drain body for a secure install and accepts a removable standpipe (field-supplied) to match your protection height?simple, effective, and service-friendly.
Rather than letting sewage overflow onto the floor, the S-4F routes surcharged water up a vertical standpipe, buying time until pressure subsides or service arrives?ideal for heavy rain events and municipal surcharges.
A straightforward standpipe design has no power, batteries, or electronics to fail. Once installed, it passively protects the space and resets automatically as conditions normalize.
Tough gaskets and corrosion-resistant hardware are built for damp floor-drain environments. Periodic inspection and occasional gasket cleaning are typically all that?s needed.
The S-4F threads into a 4? drain body for a secure, reversible install?no breaking concrete or repiping. Add a field-supplied standpipe to set your desired protection height (see manual for pipe/thread details).
Designed for standard 4? floor drains in basements, utility rooms, and garages. For other sizes or float-type flood guards, see the matching models in the Flood-Guard? family.
Choose a standpipe height that keeps water in the pipe and away from finishes while remaining accessible for monitoring. Always follow local code and manufacturer guidelines.
