About this pillar

Most toilet problems are one of five things, and four of them you can fix yourself.

A running toilet wastes 6,000 gallons of water a month. A wobbly toilet leaks slowly enough that you don’t notice until the subfloor rots. A clog at 11 PM on a Sunday becomes a $400 emergency plumber call if you don’t have a plunger.

These are the five categories of problem we cover, in the order they’re most likely to happen.

  • The clog – the panic moment. Plunger, hot water, snake.
  • The runner – the slow drip that doubles your water bill. Flapper, fill valve, float.
  • The wobble / leak – wax ring, flange, shims, caulk.
  • Installation & replacement – full DIY toilet swap with photos.
  • The weird stuff – gurgling, sewer smell, water in the bathtub.
