Overview

Heavy-Duty In-Drain Heating Cable with GFCI for Sewer, Septic & Wastewater Lines

YeloDeer IPHC-DMa is a heavy-duty 5W/ft self-regulating in-drain heating cable for freeze protection inside sewer lines, septic outlets, waste drain pipes, sump discharge lines, and other demanding wastewater applications. Its reinforced cable construction supports continuous runs up to 180 ft from one power connection.

Quick Fit Check

GFCI Plug Included Integrated GFCI protection on standard 120V models.

Up to 180 ft One continuous cable with no intermediate connection.

5W/ft Output Higher heat output for more demanding winter drain applications.

Reinforced Cable Thicker, firmer construction for long and demanding pipe runs.

Not pressure rated. Its reinforced construction provides greater resistance to limited incidental internal pressure than the compact IPHC-DMi, but it is still intended for open or vented drain layouts—not pressurized plumbing, potable-water pipes, or sealed water-supply lines.

Why Choose the Heavy-Duty Version?

Built for Demanding Drain Conditions The larger 0.42 × 0.20 in cable uses a more robust conductor, shield, thicker corrosion-resistant jacket, and sealed-tail construction for sewer and wastewater environments.

Easier Long-Run Insertion The firmer cable body is easier to advance through longer, relatively straight pipe runs and reaches up to 180 ft without an intermediate connection.

Built-in GFCI: Plug directly into a properly grounded receptacle. Do not connect this model to an additional GFCI-protected outlet.

Automatic Temperature Control

Self-regulating does not mean automatic shutoff. The cable adjusts heat output as temperature changes but remains energized while connected to power. Add the YeloDeer Pipe Heat Tape Thermostat Controller, sold separately, for automatic temperature-based on/off control.

Pipe Requirements

Recommended Pipe Size	2 in and larger sewer, septic, drain, or wastewater pipe
Pressure Condition	Open or vented drain layouts only; more resistant to limited incidental internal pressure than IPHC-DMi, but not pressure rated
Required Pipe Layout	Accessible inlet with an open or vented downstream outlet
Possible Entry Points	Open pipe end, cleanout, drain outlet, or another suitable accessible opening
Internal Route	Clear route without blockage, collapse, crushing, or sharp restrictive bends

Do Not Use This Product For

Pressurized drinking-water lines or potable-water supply pipes
Sealed plumbing that can build internal water or air pressure
Pipes smaller than 2 in unless compatibility is confirmed before ordering
Blocked, collapsed, crushed, leaking, or unknown internal pipe routes
Routes that require the cable to be forced through sharp elbows or restrictions
Applications where the cable may be cut, crushed, or contacted by moving equipment

For a smaller open condensate or drain line, compare the compact IPHC-DMi drain heating cable. For a pressurized potable-water pipe, use a pressure-rated YeloDeer potable in-pipe heating cable instead.

Select the Correct Length

Measure from the planned cable-entry point to the farthest freeze-prone section. Include accessible bends and exposed drainage sections, but do not select a length that requires sharp coiling inside the pipe.

Do not cut, shorten, splice, or modify the heating cable. It is factory terminated. If you need a non-standard length or 240V version, contact YeloDeer before ordering.

A 240V version does not automatically use less energy. Its main advantage is supporting longer cable runs with lower current. Confirm voltage, length, pipe diameter, and application before placing a custom order.

Installation

Self-regulating sewer pipe heating cable with GFCI plug

Basic Installation Sequence

Confirm the pipe is non-pressurized and both ends remain open or vented for normal drainage.
Shut down related equipment and make the work area safe.
Thaw and clear any existing frozen blockage before inserting the cable.
Measure the freeze-prone route and verify the cable can pass without force.
Insert the cable through an open pipe end, cleanout, drain outlet, or other suitable access point.
Advance it slowly and stop if it reaches a sharp bend, restriction, or obstruction.
Plug the standard 120V model directly into a properly grounded receptacle; do not connect it to an additional GFCI-protected outlet.
Keep the power cord, GFCI plug, outlet, and all electrical connections dry and weather protected.
Test the built-in GFCI before operation and periodically during the season. Never bypass it.
Restore normal drainage and verify the cable does not obstruct wastewater flow.

Use the built-in GFCI as the cable's ground-fault protection. Adding a second GFCI-protected outlet can cause nuisance tripping and make resetting more difficult. If the built-in GFCI trips repeatedly, disconnect the cable and inspect the installation before using it again.

Do Not ForceResistance indicates a bend, blockage, restriction, or unsuitable route.

Do Not CutStandard cables are factory terminated and cannot be shortened in the field.

Protect the JacketAvoid sharp pipe edges, crushing, scraping, and hard kinks.

Keep Drainage OpenDo not seal the cable into a pipe that can build pressure.

Protect ConnectionsGFCI protection does not make plugs or outlets waterproof.

Insulate When SuitablePipe insulation can reduce heat loss on exposed drain sections.

Optional Automatic Control

Connect the heating cable through the compatible YeloDeer Pipe Heat Tape Thermostat Controller to switch power automatically according to pipe temperature. Keep the total connected load within the controller rating.

FAQ

Is this cable pressure rated?

No. It has no water-pressure rating and is intended only for non-pressurized sewer, septic, drain, sump, and wastewater pipes. Do not use it in pressurized plumbing or potable-water supply lines.

Must both ends of the pipe remain open?

Yes. Use it where the cable has an accessible entry and the downstream pipe end remains open or vented for normal drainage. Do not install it in a sealed pipe that can build pressure.

Why does this version include a GFCI plug?

The integrated GFCI provides ground-fault protection for the standard 120V drain-heating cable. Plug it directly into a properly grounded receptacle rather than an additional GFCI-protected outlet. The GFCI does not make the plug waterproof or replace required weatherproof outlets, covers, grounding, or other applicable electrical requirements.

Can it be used in sewer or septic lines?

Yes, when the pipe is non-pressurized, 2 in or larger, has a suitable open access point, and remains open or vented for drainage.

How is it different from the compact IPHC-DMi?

IPHC-DMa uses a thicker 0.42 × 0.20 in reinforced cable, provides 5W/ft, includes an integrated GFCI on standard 120V models, and reaches 180 ft from one power connection. Its firmer body is easier to advance through long, relatively straight sewer and wastewater lines. IPHC-DMi is a smaller 0.31 × 0.19 in cable for condensate and open drain lines under 2 in, offers 3W/ft or 5W/ft, has no integrated GFCI, and reaches up to 75 ft.

Does the cable turn itself off?

No. Self-regulating cable reduces heat output as temperature rises but remains energized. Use the compatible YeloDeer pipe heat tape thermostat controller for automatic on/off control.

Can it operate in a dry or temporarily empty drain?

Yes, when installed in a suitable non-pressurized drain route. The self-regulating cable adjusts output with temperature, but all pipe-layout and electrical requirements still apply.

Can the cable pass through elbows?

Only gradual bends that allow smooth insertion. Do not force the cable through sharp elbows, restrictions, or unknown obstructions.

Can I cut the cable to length?

No. Measure the route before ordering and select the correct finished length. Contact YeloDeer for a custom-length or 240V project.
