MAXKOSKO 120V In-Pipe Heating Cable for Water, Sewer & Drain Pipes, CSA Certified Self-Regulating Heat Trace with GFCI

5W Heavy-Duty In-Pipe Heating Cable for Sewer & Wastewater Lines MAXKOSKO Heavy-Duty In-Pipe Heating Cable is designed for freeze protection inside compatible non-pressurized or low-pressure sewer, septic, wastewater, sump discharge, and larger drain pipes. With approximately 5W/ft heating output at 50°F (10°C), this model provides stronger heating performance than the compact 3W drain cable, making it better suited for larger pipes and demanding wastewater applications. Heavy-Duty 5W/ft Output Provides higher heating output for larger sewer, septic, sump, and wastewater pipes exposed to severe freezing conditions. For Non-Pressurized Wastewater Designed specifically for compatible sewer, septic, waste drain, sump discharge, and other non-potable drainage systems. Corrosion-Resistant Jacket The fluoropolymer outer jacket helps protect the cable in wet, corrosive, and demanding wastewater environments. Built-In GFCI Plug Integrated GFCI protection helps provide additional electrical safety for properly installed wet-location applications. Important Before Ordering For Heavy Wastewater Applications Only Not for Drinking Water: This model is not intended for potable water pipes, household water supply lines, wells, or other pressurized drinking-water systems. Low or No Water Pressure: Use only in compatible non-pressurized or low-pressure sewer, septic, sump, wastewater, and drain systems. Recommended Pipe Size: Best suited for drain and wastewater pipes approximately 2 in and larger. Smaller pipes require enough internal clearance for safe cable insertion. Confirm the Entry Point: A cleanout, open pipe end, drain outlet, or compatible access fitting is required. Entry hardware is not included unless specifically listed in the selected package. Do Not Install in a Blocked Pipe: Thaw, clear, and inspect any frozen, clogged, collapsed, leaking, or damaged pipe before inserting the heating cable. Avoid Sharp Bends: Do not force the cable through sharp elbows, narrow fittings, unknown routes, or mechanical obstructions. Fixed-Length Cable: Select the correct heating length before ordering. Do not cut, shorten, splice, or modify the heating cable. Self-Regulating Is Not Auto-Off: The cable adjusts its heat output as temperature changes but remains powered until disconnected or controlled by a compatible thermostat.

Confirm that the line is non-potable and does not operate under high water pressure. Clear and inspect the pipe before inserting the cable. Confirm the cable can pass through the entire route without force. Do not install through sharp elbows, crushed sections, roots, debris, or unknown blockages. Use a suitable access point and protect all outdoor electrical connections from moisture. Test the GFCI plug and cable before winter operation. Refer to the complete installation instructions before use. Frequently Asked Questions Can this cable be used in drinking-water pipes? No. This heavy-duty model is intended for non-potable sewer, septic, sump, wastewater, and drain systems. Use a MAXKOSKO drinking-water in-pipe cable for pressurized potable water lines. What pipe size is recommended? It is primarily recommended for wastewater and drain pipes approximately 2 in and larger. Confirm that the complete internal route provides enough clearance before ordering. Why choose this 5W model? The higher 5W/ft output is better suited for larger pipes, heavier wastewater applications, and more demanding winter freeze conditions than the compact 3W drain model. Can it be used in a pressurized sewer or water line? It is intended for non-pressurized or low-pressure wastewater systems. Do not use it in pressurized drinking-water supply lines. Can the cable clear an existing blockage? No. The cable is intended for freeze prevention. Roots, debris, collapsed pipe, poor slope, solid waste, and existing ice blockages must be cleared before installation. Does it turn itself completely off? No. Self-regulating technology adjusts heat output but does not disconnect electrical power. Use the MAXKOSKO 120V Thermostat Controller for automatic temperature-based switching. Controller & Product Selection For automatic operation and reduced unnecessary energy use, pair the cable with the MAXKOSKO 120V Pipe Heating Cable Thermostat Controller. For smaller condensate or open drain lines, consider the MAXKOSKO 3W Compact Drain Pipe Heating Cable. For pressurized drinking-water systems, choose the Standard Drinking Water In-Pipe Cable or the Y-Fitting Drinking Water Cable.
