To thaw frozen hot water pipes under your mobile home, you can follow a few practical steps. First, make sure the heat wrap is functioning properly and has power. If it’s not working, you may need to replace it or ensure it’s plugged in.
Next, you can use a space heater or a hairdryer to gently warm the affected areas of the pipes. Start at the faucet and move towards the pipe leading to the water heater, applying heat gradually. Avoid using open flames or high heat, as this can damage plastic pipes.
If the pipes are still frozen after trying these methods, you may want to consider using warm towels soaked in hot water. Wrap them around the frozen sections of the pipes to help thaw them out.
If you’re unable to resolve the issue or if there are signs of damage, it's best to contact a licensed plumber. Costs for plumbing services can range from $100 to $300 per hour, depending on your location and the complexity of the issue.
