Does boiling water ruin pipes?

Yes, pouring boiling water down pipes, especially plastic PVC pipes common in modern homes, can be bad because its 212°F (100°C) temperature exceeds the pipes' tolerance (around 140°F/60°C), potentially softening, warping, melting joints, or damaging seals, leading to leaks, though metal pipes (copper, cast iron) handle it better. It's safer to use very hot tap water or mix boiling water with cold water to lower the temperature, or use a plunger/snake for clogs instead.

Why is my toilet smelling like sewage?

A sewage smell from your toilet usually means sewer gas is escaping due to a dry P-trap (water seal), a damaged wax ring (seal at the toilet base), a clogged or blocked vent pipe, or a clogged drain or sewer line issue, all preventing proper gas escape or allowing backup. The most common culprits are simple fixes like adding water to unused traps or baking soda/vinegar for minor clogs, but persistent smells often need a plumber for broken seals, vent pipe problems, or sewer line damage. 

How to tell if your sewer line is clogged?

You can tell if your main sewer line is clogged by observing multiple slow drains, gurgling sounds from toilets or tubs, foul sewage odors, and water backing up into low-level drains or the sewer cleanout pipe in your yard.
