Overview
Heavy-Duty In-Pipe Heating Cable for Sewer, Septic & Waste Drain Systems
YeloDeer IPHC-DMa is a heavy-duty self-regulating in-pipe heating cable designed for non-pressurized sewer lines, septic systems, waste drain pipes, sump pump discharge lines, downspout drain lines, and larger drainage applications where freezing can block wastewater flow during winter.
This model is built specifically for sewer and drain environments. It delivers 5W/ft heating output at 50°F / 10°C and uses a corrosion-resistant fluoropolymer outer jacket to help withstand harsh wastewater conditions.
This product is ideal for customers who need to protect underground drain lines, septic outlets, large-diameter waste pipes, or exposed drain openings from freezing, ice buildup, and winter blockage.

Important Before You Order
This cable is for non-pressurized sewer, septic, drain, and wastewater applications. It is not intended for pressurized drinking water supply lines. If you need freeze protection for potable water lines, please choose YeloDeer’s standard in-pipe heating cable or Y-fitting in-pipe heating cable instead.
For best results, confirm your pipe diameter, access point, cable route, freezing section length, and whether your pipe needs to remain sealed after installation.
If your system is a closed drain or sewer pipe that must be sealed after inserting the cable, a sealing accessory may be required. YeloDeer offers optional sealing end caps for 3 in and 4 in pipes, sold separately. If a T-type connector is needed for your installation, please note that it is not included.
Self-Regulating Does Not Mean Auto-Off
This cable automatically increases heat output in colder areas and reduces output in warmer areas. However, it does not shut off completely by itself. To fully stop heating, unplug the cable or use a compatible temperature controller.
For automatic seasonal operation and improved energy savings, we recommend using this cable with a thermostat, sold separately.

How to Choose the Right Length
Measure from the cable entry point to the farthest section that needs freeze protection. Add extra length for bends, access points, and the outside sealing area if needed.
We recommend choosing the next standard length up rather than choosing a cable that is too short.
Before selecting your length, confirm:
• Where the cable will enter the pipe
• How far the freezing section extends
• Whether the pipe has bends or restricted areas
• Whether the pipe must be sealed after installation
• Whether you need 120V or 240V
• Whether the cable will be used in an open drain or closed drain
Important Sizing Note
This cable cannot be cut or shortened in the field. It is factory terminated and not field-spliceable.
If the cable is slightly longer than needed, the excess length may be managed near the entry area or, in larger pipes, routed carefully inside the pipe without forcing sharp bends. Do not cut the heating cable.
When to Choose 240V
A 240V cable does not automatically use less energy than a 120V cable. Energy usage is based on wattage and operating conditions.
The main advantage of 240V is that it can support longer cable runs with lower current, making it useful for longer sewer, septic, or drain applications.
For custom 240V orders, please contact yelodeer@yelodeer.com with your required length, pipe diameter, application, and installation photos if available.
Installation & Accessories
Basic Installation Overview
This cable is designed to be inserted inside a non-pressurized sewer, septic, drain, or wastewater pipe through a suitable access point.
Typical installation steps:
1. Identify the freezing section of the pipe.
2. Choose a suitable entry point, such as a cleanout, open pipe end, drain outlet, or access fitting.
3. Confirm the pipe is not blocked, collapsed, or too narrow for the cable.
4. Insert the cable into the pipe carefully.
5. Use fish tape or a guide tool for longer pipe runs if needed.
6. Avoid forcing the cable through sharp bends or restricted areas.
7. If the pipe must be sealed, use the appropriate sealing accessory.
8. Plug the cable into a properly protected outlet.

FAQ & Resources
Additional Product Questions
1. Is this cable for potable water pipes?
No. This model is designed for non-pressurized sewer, septic, drain, and wastewater systems. For drinking water supply lines, please choose YeloDeer’s potable in-pipe heating cable or Y-fitting in-pipe heating cable.
2. Can this cable be used in a dry or empty pipe?
The self-regulating heating cable reduces output as the surrounding temperature rises, which helps reduce overheating risk. However, the cable should still be installed according to the product instructions and should not be crushed, cut, or exposed to unsafe conditions.
3. Can I use this cable in a downspout drain line?
Yes, it can be used in suitable non-pressurized downspout drain lines if the pipe diameter, cable route, entry point, and power connection are compatible. Outdoor electrical connections must be protected from moisture.
4. Can the cable pass through elbows?
It may pass through smooth bends if there is enough internal space and the bend radius is not too tight. Do not force the cable through sharp elbows, blocked sections, crushed pipe, or unknown pipe routes.
5. Will the cable block wastewater flow?
In properly sized 2 in or larger drain and waste pipes, the cable is designed to sit inside the pipe while allowing wastewater to pass. Avoid using it in undersized, blocked, or debris-heavy lines where flow may already be restricted.
6. Do I need to insulate the pipe?
For exposed above-ground sections, insulation can improve freeze protection and energy efficiency. Underground sewer and drain pipes may not need external insulation, but exposed openings, access points, or above-ground sections should be protected when possible.
7. Can this cable be used for a septic tank outlet?
Yes. This product is designed for non-pressurized septic and sewer applications, including septic tank outlet freeze protection when the pipe size and access point are compatible.
8. What information should I send for a custom order?
Please send:
• Pipe type
• Pipe diameter
• Required heating length
• Voltage requirement: 120V or 240V
