Yes, hot and cold water lines can cross. Here are the reasons why:
• Temperature fluctuations may be minimal due to insulation.
• It is often more cost-effective than installing two separate sets of pipes.
• Crossed water lines reduce the amount of pipe needed for a plumbing system, thus reducing installation time and costs.
Crossing hot and cold water lines should only be done with an experienced plumber’s supervision to ensure proper functionality and safety.
