The WATCO flex916-zri-pvc-cp Innovator is a complete flexible bath waste kit designed for residential bathtub drain installations where rigid PVC overflow pipe creates alignment challenges. The kit includes 16 inches of flexible PVC tubing that replaces a standard rigid overflow pipe, allowing the overflow tube to bend and conform when the drain pipe and overflow hole are not in perfect alignment. Rated for Schedule 40 PVC applications, it ships as a standard full kit with a lift and turn bathtub stopper included. Licensed plumbers install this kit during rough-in or remodel work on standard residential tub drain assemblies.
This waste kit is suited for bath installations where rigid overflow pipe cannot achieve a clean connection due to wall framing, tub positioning, or drain pipe misalignment. The flexible tubing absorbs minor positional variances without requiring structural adjustments, making it a practical choice for remodel and replacement projects. The lift and turn stopper provides a reliable, mechanical drain closure that does not require additional trim hardware to operate. Installations that involve older tubs or non-standard rough-in dimensions benefit from the adjustability this flexible design provides.
Designed as an OEM-style replacement and new-installation waste kit for residential bathtub drain assemblies requiring Schedule 40 PVC flexible overflow connections.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and ensure the tub is fully accessible before beginning drain assembly work. Route the flexible tubing carefully to avoid kinking, and verify that all slip-joint connections are fully seated and secured before closing the access panel. Do not overtighten PVC fittings, as this can crack the material and compromise the drain seal.
