Replacing a gas water heater involves removing the old unit and installing a new one. It requires knowledge of plumbing, gas lines, and electrical connections. Attempting this task without proper expertise can be dangerous and could lead to gas leaks, water damage, or electrical hazards.
If you are considering changing a gas water heater, it is essential to weigh the importance of professional installation versus DIY. While DIY can save money, professional installation offers peace of mind and ensures the job is done correctly and safely.
