These tasks involve safety risks, code requirements, or specialized equipment that require a licensed plumber:
Water heater installation or major repair
Gas lines, electrical, and pressure require expertise and permits

Anything involving the main water line
Mistakes can flood your home and affect neighbors

Risks of Delaying Professional Help
Putting off a repair that needs professional attention often makes things worse:
Small leaks
Water damage compounds over time. A $150 repair becomes a $5,000 restoration.
Slow drains
Partial clogs become complete blockages, potentially backing up sewage.
Running toilets
Can waste 200+ gallons per day, and mask developing tank issues.
Low water pressure
May indicate hidden leaks or pipe corrosion that will worsen.
Water heater problems
Minor issues become complete failures, often at the worst times.
