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 or potable water pipes. If you need freeze protection for drinking water lines, choose YeloDeer’s standard in-pipe heating cable or Y-fitting in-pipe heating cable instead.
Your pipe is a non-pressurized sewer, septic, drain, sump, or wastewater line
Your pipe diameter is 2 in or larger, unless confirmed suitable
You have a cleanout, open pipe end, drain outlet, or compatible access point
The internal pipe route is not blocked, collapsed, crushed, or unknown
The cable can pass without being forced through sharp bends
You know whether the pipe is open or must remain sealed
You have measured the freeze-prone length from the entry point
Your outdoor outlet and plug connection can be weather protected
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, use this cable with a YeloDeer Pipe Heat Tape Thermostat, sold separately.
Need a Custom Length or Voltage?
Standard products are 120V. If you need a custom length or 240V version, select the “Custom: Any Size/Volt” option or contact us at yelodeer@yelodeer.com.
After a custom order is placed, our team will contact you by email within 1 business day to confirm your voltage, length, pipe type, and installation requirements.

IPHC-DMa vs IPHC-DMi
Choose IPHC-DMa If
You need a larger, stronger cable for sewer, septic, or large drain pipes, 5W/ft output, built-in GFCI protection, 2 in and larger pipe compatibility, optional sealing, or stronger winter drain protection.
Choose IPHC-DMi If
You need a smaller and more compact cable, open drain applications only, drains smaller than 2 in, or a more economical option where GFCI protection is already provided by the circuit.
If your pipe is smaller than 2 in, has very tight bends, or has limited internal space, the smaller IPHC-DMi model may be a better option for open drain applications.
When Not to Use This Product
- Pressurized drinking water supply pipes
- Potable water lines
- Pipes smaller than 2 in unless confirmed suitable
- Pipes with blocked, collapsed, or unknown internal conditions
- Pipes with very sharp bends where the cable cannot pass safely
- Applications where the cable may be crushed, cut, or exposed to moving mechanical parts

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.
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. Do not cut, splice, or modify the heating cable.
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.
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, contact yelodeer@yelodeer.com with your required length, pipe diameter, application, and installation photos if available.
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
- Identify the freezing section of the pipe.
- Choose a suitable entry point, such as a cleanout, open pipe end, drain outlet, or access fitting.
- Confirm the pipe is not blocked, collapsed, or too narrow for the cable.
- Insert the cable into the pipe carefully.
- Use fish tape or a guide tool for longer pipe runs if needed.
- Avoid forcing the cable through sharp bends or restricted areas.
- If the pipe must be sealed, use the appropriate sealing accessory.
- Plug the cable into a properly protected outlet.
- For outdoor power connections, use a weather-protected outlet and an in-use cover.
- Use a thermostat if you want automatic on/off control.
Installation Notes
Do Not Cut or Splice
The cable is factory terminated and not field-spliceable.
Do Not Crush or Force
Do not crush, sharply bend, or force the cable through blocked or collapsed pipe sections.
Maintain Bend Radius
Keep the minimum bend radius at 1-1/2 in at 32°F / 0°C.
Use Protected Power
Use proper GFCI-protected power supply and protect outdoor outlets from weather.
Seal Closed Pipes
If the pipe is closed and must remain sealed, use a compatible sealing accessory.
Consider Professional Help
For complex sewer, septic, or underground drainage systems, professional installation is recommended.
Electrical & Wastewater Installation Notice: Keep all electrical connections dry and protected from rain, snow, and standing water.
Do not use the cable in blocked, collapsed, unknown, or mechanically unsafe pipe routes. Do not install where the cable may be cut, crushed, caught in moving parts, or damaged by sharp internal edges.

Temperature Controller Recommendation
The cable can operate by plugging directly into power, but a thermostat is recommended if you want automatic temperature-based control.
A thermostat helps turn the heating system on only when needed, reduce unnecessary winter electricity use, avoid manual plugging and unplugging, manage seasonal temperature changes, and improve long-term operating convenience.
The thermostat is sold separately.
The installation photos below show how customers use YeloDeer heavy-duty in-pipe heating cable in real sewer, septic, drain, sump discharge, and wastewater applications.
Every drainage system is different. Pipe diameter, entry point, pipe condition, bends, underground layout, and sealing requirements can all affect installation.
Before Ordering, Please Check
Where the cable will enter the pipe
The pipe diameter
The total length that needs freeze protection
Whether the pipe is open or closed
Whether a sealing accessory is required
Whether the pipe has sharp bends or restricted sections
Whether the power outlet is protected from weather
Whether professional installation is needed
If you are unsure which length or accessory to choose, send your installation photos and pipe details to yelodeer@yelodeer.com. Our team can help review your application before you order.
