Installation

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 route and verify the selected cable length and output.
Insert the cable slowly through the accessible open pipe end.
Stop if it reaches a sharp bend, restriction, blockage, or unknown obstruction.
Keep the power connection outside the pipe and protected from moisture.
Provide grounding, overcurrent protection, and ground-fault protection required for the installation.
Restore normal drainage and confirm the cable does not obstruct flow.

Do Not Force Use gentle hand pressure and stop when resistance increases.

Do Not Cut Standard cables cannot be shortened or spliced in the field.

Protect the Jacket Avoid sharp edges, scraping, crushing, and hard kinks.

Keep Both Ends Open Do not seal this cable into a pipe that can build pressure.

Protect the Circuit This version has no integrated GFCI plug.

Insulate When Suitable Insulation can reduce heat loss from exposed drain sections.

FAQ

Does this version include a GFCI plug?

No. IPHC-DMi does not include an integrated GFCI. Provide the grounding, circuit protection, and ground-fault protection required for the installation and applicable electrical requirements.

Is this cable pressure rated?

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

Must both ends of the pipe remain open?

Yes. This original version requires an accessible open entry and an open or vented downstream outlet. For a 1/2 or 3/4 in PVC/ABS drain that must remain closed after installation, compare the DrainGuard kit.

How is DrainGuard different?

DrainGuard includes a 3/4 in Y-fitting, 1/2 in adapters, gasket, sealing grommet, lock nut, and pipe nipples. These parts create a dedicated cable-entry point and help restore a sealed drainage path. It remains limited to non-pressurized, low-pressure drain applications.

What is the difference between 3W/ft and 5W/ft?

The 3W/ft version suits typical condensate and small drain applications. The 5W/ft version provides higher heat output for colder exposure, longer outdoor sections, or greater heat loss.

Can this cable be used for sewer or septic lines?

This compact model is primarily intended for condensate and small open drain lines under 2 in and up to 75 ft. For larger, longer, or more demanding sewer, septic, and wastewater pipes, choose the heavier IPHC-DMa with integrated GFCI and continuous lengths up to 180 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 open drain route. All electrical, pipe-layout, and installation requirements still apply.

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 project.

Common Questions

How does IPHC-DMi compare with the heavy-duty IPHC-DMa?

IPHC-DMi is the compact option for open, non-pressurized condensate and drain lines under 2 in. It has no integrated GFCI; 3W/ft versions are available up to 75 ft and 5W/ft versions up to 50 ft.

For 2 in and larger sewer or wastewater lines and longer runs, compare the IPHC-DMa, which has integrated GFCI protection and continuous lengths up to 180 ft. Select by pipe size, route and installation requirements. Neither this comparison nor a sealed entry fitting makes a drain cable suitable for pressurized drinking-water plumbing.

Is this cable pressure rated or suitable for drinking-water pipes?

No. IPHC-DMi has no water-pressure rating and is not for potable-water supply lines, pressurized plumbing or pipes that can build pressure. Use it only in suitable non-pressurized drain applications.

For water-supply freeze protection, compare the T-fitting in-pipe model or Y-fitting in-pipe model, and check the selected product's pipe-size and pressure requirements.

Can I order a custom heating length?

Custom lengths may be available by request. Standard sizes are usually more cost-effective, and a shorter custom cable may cost more than a standard length.

Email yelodeer@yelodeer.com with the heating length, pipe diameter, application and photos so we can confirm availability and suitability before you order.

Can I cut, shorten or splice the cable?

No. This is a factory-terminated cable. Do not cut, shorten, splice or modify it. Cutting can damage the product and create an electrical safety risk. Measure the installation route and select the correct finished length before ordering.

How do I choose the correct cable length?

Measure from the open cable-entry point to the farthest section that needs freeze protection, including exposed and hidden cold sections along the route. Check bends, access and restrictions; do not select a length that requires sharp coiling inside the pipe or force the cable through obstructions.

The listed length is the heating section. The power cord is approximately 6 ft, so a 5 ft heating cable is approximately 11 ft in total. The power cord must remain outside the pipe, with its connection protected from moisture.

Can it operate in a dry or temporarily empty drain?

Yes, when installed in a suitable open, non-pressurized drain route, such as a condensate line with intermittent flow. Required pipe layout, grounding, circuit protection and installation conditions still apply. Self-regulating performance does not make an unsuitable or blocked pipe safe to use.

Does a self-regulating cable switch itself off?

No. It adjusts heat output as temperature changes but remains energized while connected to power. A compatible pipe heat tape thermostat controller, sold separately, provides temperature-based on/off control and can reduce unnecessary operating time. Keep the connected load within the controller's rating.

Can I use it outdoors, and how should I protect the power connection?

Yes, in a suitable drain installation. Keep the plug, outlet and all connections outside the pipe and protected from moisture. Use the required protected outlet and a weatherproof in-use cover; do not leave electrical connections in standing water, snow or direct rain exposure.

Follow the product instructions for extension-cord use. Any permitted cord must be suitable for the environment, connected load and total cord length. Do not select a cord by wire gauge alone.

When should I use a professional installer?

An open, accessible drain with a clear route may be straightforward to install. Use a qualified professional for electrical work, unknown or underground routes, restricted access, suspected blockage or damage, and complex sewer or drainage layouts.

Confirm the correct model before work begins. A need for a sealed entry does not by itself determine the cable model; the pipe size, pressure conditions and compatible entry assembly must also match. Do not force a cable through a blockage or an unknown route.

Does IPHC-DMi include a GFCI plug?

No. IPHC-DMi does not include an integrated GFCI. Provide the grounding, overcurrent protection and ground-fault protection required by the product instructions and applicable electrical requirements.

Must both ends of the drain remain open?

This version requires an accessible open entry and an open or vented downstream outlet for normal drainage. Do not seal it into a pipe that can build pressure, and make sure the cable does not obstruct drainage. If you need a dedicated sealed cable-entry assembly for a small condensate drain, compare DrainGuard and confirm its application limits.

When is DrainGuard a better fit?

DrainGuard is designed for 1/2 or 3/4 in PVC/ABS condensate or low-flow drains that need a cut-in Y-fitting and a dedicated sealed cable-entry assembly. Its kit includes the matching fitting, adapters and sealing components.

DrainGuard is still a drain application, not a solution for pressurized plumbing or potable-water supply pipes. Check its installation requirements before selecting it.

Should I choose 3W/ft or 5W/ft?

The 3W/ft option suits typical condensate and small drain applications with suitable insulation. The 5W/ft option provides higher output for colder exposure, longer outdoor sections or greater heat loss. Published output is rated at 50°F / 10°C; self-regulating output varies with conditions.

Choose both the output and finished length before ordering. Available 3W/ft lengths extend up to 75 ft; 5W/ft lengths extend up to 50 ft. Contact us if the drain layout or winter exposure is uncertain.
