The OATEY 80391 is a non-acid liquid drain opener sold in a 1-quart container, formulated to clear blocked drains in residential and light commercial plumbing systems. Licensed plumbers and service technicians reach for non-acid drain openers when working on systems where acid-based chemicals pose a corrosion risk to pipes, fittings, or surrounding fixtures. The 80391 is the Cloroben PT-B101 formulation, a recognized drain-clearing solution designed to break down organic blockages such as hair, grease, and soap buildup without the aggressive pipe damage associated with strong acid products.
This drain opener is suited for use in sink drains, floor drains, shower drains, and similar waste-line applications in residential homes, apartment buildings, and light commercial settings. It is typically applied directly into the drain opening and allowed to dwell before flushing with water. Plumbers carrying it on service trucks can address common soft blockages without heavy mechanical intervention, making it a practical chemical option for routine drain service calls.
Designed as a chemical drain-clearing solution for use in standard residential and light commercial drain and waste-line applications where a non-acid formulation is appropriate.
This product is handled and applied by licensed plumbers or qualified service technicians following chemical safety protocols. Always wear appropriate personal protective equipment including gloves and eye protection when handling drain-opening chemicals. Ensure the work area is ventilated and follow all label directions for dwell time and flushing procedures. Do not mix with other drain-cleaning chemicals or introduce into systems where chemical compatibility has not been verified.
