An in-pipe heating cable is one of the most reliable ways to protect water lines from freezing in harsh winters. Products like the YeloDeer In-Pipe Heating Cable are designed for durability and 100% factory tested for safety. Still, some users occasionally face leaks, often at the black union fitting where the cable enters the pipe.
This guide covers the six most common reasons for leaks, what to do if it happens, and simple steps to prevent issues so your pipe freeze protection runs worry-free.
Six Common Causes of Leaks
1. Manufacturing Defects (Rare)
Every YeloDeer cable is 100% water and voltage tested before shipping, so factory defects are extremely rare. Still, users should inspect the cable visually on arrival for any obvious cracks or damage.
2. Shipping or Handling Damage
Rough transit or dropping the unit can crack seals or fittings. Before installation, check for dents, kinks, or loose parts. If something looks off, don’t install it, request a replacement.
3. Installation Damage
The most common cause of leaks is user error during installation.
1. Avoid scratching the jacket on threads or fittings.
2. Don’t over-bend the cable, especially at the end seal.
3. After installation, always run a 24-hour pressure test. If there’s a flaw, it will show up before winter.
4. Loose Fittings or Gaskets
If the union fitting isn’t tightened or the rubber gasket isn’t seated correctly, water can drip. The fix is usually simple: turn off water, re-seat the gasket, and re-tighten the fitting snugly.
5. High Water Pressure
YeloDeer in-pipe heating cables are rated to 230 PSI, well above normal home ranges (40–80 PSI). If your system runs unusually high, seals may fail. Install a pressure regulator if needed — damage from overpressure isn’t covered by warranty.]
6. Lightning or Electrical Surges
A lightning strike or surge can damage the cable’s braided layer or burn pinholes in the insulation. This is rare, but also not covered under warranty. Using a surge protector is the best safeguard.
What to Do If You Find a Leak
1. Shut off water and power immediately to stop the leak and ensure safety.
2. Contain drips with a pail or towels to prevent flooding.
3. Document the issue: note your order number, take photos or a short video.
4. Contact YeloDeer support with details for fast warranty evaluation.
Tips to Prevent Future Leaks
1. Handle with care: never force the cable through sharp elbows or over-tighten fittings.
2. Double-check fittings and gaskets during install and after 24 hours.
3. Test water pressure: keep it below 80 PSI for best performance.
4. Use surge protection to defend against rare lightning or power spikes.
5. Follow YeloDeer’s instructions exactly for installation and testing.
Conclusion
Most leaks from an internal pipe heater can be avoided with careful installation, routine checks, and proper water pressure. By knowing the six main causes, and how to respond quickly, you’ll keep your YeloDeer In-Pipe Heating Cable running safely for years, ensuring your home’s water never freezes even in the coldest winters.
