The PASCO SPECIALTY MFG CO 1855 is a cleanout plug designed for drain, waste, and vent (DWV) piping systems. Cleanout plugs seal cleanout access points in drainage lines, preventing sewer gases from escaping and maintaining system pressure integrity between service intervals. This part is sold as a single unit and is identified by manufacturer part number 1855. Licensed plumbers install cleanout plugs during new construction, remodel work, and routine drain system maintenance.
Cleanout plugs are used in residential and light commercial plumbing systems wherever a cleanout fitting is present. They are installed at the terminus of a cleanout riser or at in-line cleanout fittings to provide a serviceable access point for drain snaking and hydro-jetting operations. The 1855 is a single replacement unit, suitable for restoring a cleanout access point to a sealed, code-compliant condition.
Designed as an OEM-style replacement cleanout plug for residential and light commercial DWV drain systems equipped with standard cleanout fittings.
Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Before servicing, isolate the drain line and confirm there is no active flow through the cleanout. Use the appropriate wrench or plug driver to seat the plug fully without overtightening. Inspect the plug and fitting threads for damage before reinstalling on an existing cleanout.
