The Internal sewer plug MAGNAPLAST HTM 75 mm (model 12520) is a sealing device designed for temporary closure of 75 mm wastewater pipes in internal drainage systems. Manufactured for compatibility with standard 75 mm sewer runs, this plug provides a reliable, removable barrier used during maintenance, leak detection, pressure testing and to prevent backflow or unpleasant odours. The product is intended for use in residential and light commercial plumbing where a compact, easy-to-install sealing solution is required.

Advantages

The MAGNAPLAST HTM 75 mm plug offers a simple mechanical sealing method that requires no permanent modification of the pipe. Its compact design enables quick insertion and removal, reducing downtime during repair or testing. The plug is constructed from materials suitable for wastewater environments, providing chemical and water resistance for routine maintenance tasks. Its compatibility with common 75 mm internal sewer lines ensures broad applicability in typical household and light-commercial installations.

Suitable for

• Temporarily sealing 75 mm internal wastewater pipes
• Pressure testing and leak detection of drainage lines
• Preventing backflow and odours during maintenance
• Short-term closure during renovation or pipe replacement

Key specifications

• Nominal pipe diameter compatibility: 75 mm internal wastewater pipes
• Type: removable internal sewer plug for temporary sealing
• Intended environment: internal drainage systems (residential and light commercial)
• Primary functions: sealing, pressure testing, backflow and odour prevention
• Design characteristics: compact, quick-installation plug suitable for confined pipe runs

How to use

Ensure the pipe section is accessible and free of large debris before inserting the plug. Insert the MAGNAPLAST HTM plug into the 75 mm pipe opening and seat it firmly to create a secure seal. If required for pressure testing, follow standard testing procedures and safety limits appropriate for the pipe material and local regulations. To remove, withdraw the plug carefully and inspect the pipe for any residues or damage. Store the plug dry and clean after use.

Usage recommendations

Use the plug only in appropriate 75 mm internal wastewater lines and avoid exposure to extreme temperatures or aggressive chemicals not suited to typical wastewater conditions. For pressure testing, adhere to relevant testing guidelines and do not exceed recommended pressure levels for the pipe system. Regularly inspect the plug for wear before reuse and replace if deformation or material degradation is observed.
