Superior 3845 Universal Sink Drain Wrench

Product Description

The SUPERIOR 3845 is a universal sink drain wrench designed for plumbing professionals and experienced DIYers working on drain and strainer installations. This tool drives and removes kitchen, bath, and laundry tub strainers, P-trap fittings, wing nuts, and tub drains using a single versatile head. Its compact form factor allows it to function in confined spaces where standard basin wrenches or channel-lock pliers cannot reach. Weighing 0.592 pounds, it is light enough to carry in a standard tool bag. Plumbers and service technicians reach for this wrench when setting or pulling drain bodies during fixture installs, rough-in work, and drain service calls.

The 3845 suits residential plumbing applications across kitchens, bathrooms, and laundry areas. It is particularly useful during new fixture installations, drain replacements, and P-trap service where access is limited by cabinet interiors or tight sink cavities. The universal fit reduces the need to carry multiple specialty sockets or spud wrenches for different drain configurations.

Installation Notes

Licensed plumbers and skilled service technicians should shut off the water supply to the fixture before removing or installing any drain or strainer assembly. Inspect drain body threads and basket seals before re-installation to confirm no damage was incurred during removal. Follow IPC guidelines for drain and trap installation clearances and sealant requirements. Avoid applying excessive torque to plastic strainer bodies, which can crack under overload.
