Online tutorials make plumbing look easy, but hidden risks can cause water damage, void warranties, and create safety issues. Here are myths to avoid—and what to do instead.
Myth 1: “Chemical Drain Cleaners Are Safe for Any Clog.”
Harsh chemicals can weaken PVC and corrode metal pipes. Professional snaking or hydro‑jetting clears blockages safely and completely.
Myth 2: “Duct Tape Fixes Leaks Long‑Term.”
Tape and quick epoxies are temporary at best. Proper repairs involve replacing failed parts and ensuring leak‑free connections.
Myth 3: “If I Don’t See a Leak, There Isn’t One.”
Slab leaks and hidden pinholes often show up as musty odors, warm flooring, or high water bills. Testing and thermal imaging help locate them.
Myth 4: “Tightening Harder Stops Drips.”
Over‑tightening can crack fittings or damage threads. The correct fix is new seals, cartridges, or components installed to spec.
Myth 5: “Permits Are Optional.”
Many projects—like water heater replacements and gas line work—require permits and inspections. Compliance protects your safety and insurance coverage.
