In-Pipe Heating Cable for Pressurized Drinking Water Lines

MAXKOSKO Self-Regulating In-Pipe Heating Cable installs directly inside compatible pressurized water pipes, providing internal freeze protection for buried, concealed, or difficult-to-wrap water lines.

This standard version includes a pre-installed 3/4 in NPT cable entry fitting. A compatible T-fitting is required for installation and must be purchased separately.

Internal Pipe Freeze Protection

Places heat directly inside the water line where external pipe wrapping may be difficult or impossible.

For Potable Water Lines

Uses a drinking-water-compatible fluoropolymer outer jacket for properly installed water supply systems.

Up to 230 PSI

Designed for compatible pressurized water pipes, well lines, cabin plumbing, and rural water systems.

120V / 240V Options

Select the voltage that matches the available electrical supply and project requirements.

Important Before Ordering

Confirm the Pipe Layout and Inspect the Cable

T-Fitting Required: A compatible T-fitting is required to create the pipe entry point. The T-fitting is not included and must be purchased separately.

Minimum Pipe Opening: Recommended for pipes 3/4 in and larger. The entire cable route, including fittings and adapters, must maintain an inner opening of at least 17 mm / 0.67 in.

Avoid Sharp Elbows: Do not force the cable through sharp 90-degree or 45-degree elbows, narrow fittings, blocked sections, collapsed pipes, or unknown internal routes.

Inspect Before Installation: Every MAXKOSKO cable is fully inspected before shipment. Before inserting it into the pipe, inspect the complete outer jacket and end seal again for cuts, abrasions, cracks, crushing, or other damage.

Do Not Install a Damaged Cable: Damage to the outer jacket or end seal may allow water leakage or electrical failure. If any damage is found, stop installation and contact maxkosko@maxkosko.com.

Insert Gently: Never pull, push, twist, hammer, or force the cable through the pipe. Violent installation can damage the outer jacket and may result in leakage.

Fixed-Length Product: Select the correct heating length before ordering. Do not cut, shorten, splice, or modify the standard cable.

Basic Installation Requirements View Requirements Hide Requirements
  • Measure the complete freeze-prone pipe section before selecting a cable length.
  • Shut off and drain the water system before installing the entry fitting.
  • Confirm at least 17 mm of internal clearance through every fitting and bend.
  • Inspect the outer jacket and end seal before inserting the cable.
  • Insert the cable slowly without forcing it through restricted sections.
  • Pressure-test and inspect all plumbing connections for leaks before operation.
  • For long runs, a fiberglass fish tape may help guide the cable when the pipe route is suitable.
  • Refer to the complete installation manual before installation.

Frequently Asked Questions

Is a T-fitting included?

No. The cable has a pre-installed 3/4 in NPT entry fitting, but a compatible T-fitting must be purchased separately.

Can this cable be used inside a drinking water pipe?

Yes. It is designed for compatible pressurized potable water lines and uses a drinking-water-compatible fluoropolymer jacket.

Can it pass through sharp pipe elbows?

No. Do not force the cable through sharp 90-degree or 45-degree elbows. The route should provide gradual bends and at least 17 mm of internal clearance.

What should I do if the cable jacket is damaged?

Do not install or energize the product. Contact maxkosko@maxkosko.com with photos of the damaged area.

Does the self-regulating cable turn itself off?

No. It adjusts heat output but does not fully disconnect power. For automatic temperature-based operation, use the MAXKOSKO 120V Thermostat Controller with compatible 120V variants.

Controller & Product Selection

For compatible 120V models, a separate MAXKOSKO Pipe Heating Cable Thermostat Controller can provide automatic temperature-based power control and reduce unnecessary operation.

Before ordering, confirm the application, pipe diameter, actual inner fitting diameter, voltage, entry fitting, pipe route, pressure, heating length, and whether the line carries potable water or wastewater.

Frequently Asked Questions (FAQs)

  • A1: No, this in-pipe heating cable is not designed to bend around sharp 90-degree or 45-degree elbow fittings. If your pipe has abrupt elbows, they need to be replaced with sections that create sweeping bends to allow the cable to pass smoothly.

    Important Notice: Forcing the cable through sharp elbows can damage the end seal, potentially causing water leakage. Many leakage issues result from improper installation, so please ensure careful installation.

  • A2: Yes, this in-pipe heating cable is designed to navigate through sweeping bends. As long as the bends are smooth and do not require sharp 90-degree or 45-degree couplers, the cable will pass through the pipe without issues.

  • A3: A thermostat is not strictly required for this in-pipe heating cable, but it is HIGHLY RECOMMENDED.

  • A4: The in-line heating cable can withstand water pressure up to 230 PSI.

  • A5: No, the GFCI typically doesn’t need to be reset after a power outage. It only requires a reset if it detects a ground fault. After a normal power loss, once the power returns, the system should work as usual unless a ground fault occurs.

  • A6: Absolutely! Our in-pipe heating cable is perfect for sump and drain pipes. The outer jacket is corrosion-resistant, making it durable for such environments. As long as the pipe diameter is larger than 3/4 inches and there are no sharp bends (like 90° or 45° angles), the cable will work seamlessly.

  • A7: No, there are no restrictions on the insertion direction of the heating cable.It can be inserted in either direction, making it suitable for both supply pipes and discharge pipes, regardless of the water flow direction.
    Designed for:
    · Water Supply Pipes:For pumping water from rivers and lakes.
    · Water Drainage Pipes:For removing water from your home.

  • A8: Yes, this product is designed for use with 3/4-inch pipes. However, please ensure there are no sections of your pipe, such as at fittings or connectors, where the inner diameter is reduced to less than 17mm (0.67 inches). If such restrictions exist, the heating cable may not fit properly.

  • A9: The key difference is circuit length capacity. A 120V system typically supports circuit lengths of up to 200 feet, while a 240V system can double the circuit length, providing more flexibility for freeze protection over longer water pipes.

  • A10: No, a 240V system does not require large cables. Standard cables like #14 or #12 are sufficient for circuits up to 15 amps.

  • A11: No, the self-regulating heating cable will not completely shut off. It adjusts power based on temperature—reducing power as the temperature rises and increasing it as the temperature drops, staying within a set range. This ensures continuous heating to prevent freezing. If you need it to completely shut off, use a Pipe Heating Controller, which will turn off the cable once the pipe temperature exceeds the set limit, offering a safer and more energy-efficient solution.

  • A12: Our self-regulating heating cable has a maximum temperature of 65°C (149°F). When the water temperature approaches this limit, the cable automatically adjusts its power to prevent further temperature rise, ensuring safety and energy efficiency. Water temperature is also influenced by factors like flow rate, pipe size, and material. We recommend using aPipe Heating Controller, which regulates the temperature to prevent overheating, and enhances energy efficiency by turning off the cable when not needed, providing added safety.
