The Things That Cause Most Kitchen and Bathroom Clogs

A drain is built to carry water, body waste and toilet tissue. Feed it anything else and sooner or later a cable machine is pulling it back out.

  • Plain steps a homeowner can follow
  • Where the DIY part ends and a plumber takes over
  • Ontario and GTA details where they matter
  • Plumbing facts, no sales pitch

Diagnosis first, tested after

Kitchen sink

  • Fats, oils and grease. They solidify in pipes and city sewers. Wipe pans, pour cooled fat into a tin and set it out with organics where your municipality allows.
  • Coffee grounds. They clump in traps.
  • Rice and pasta. They swell.
  • Eggshells and fibrous peels. Hard on disposers and drains.
  • Flour and batter. Paste in pipes.

Bathroom

  • Wipes, even “flushable” ones. They do not break down like toilet paper and tangle in pipes and pumps.
  • Dental floss, cotton swabs, hair. They bind together.
  • Paper towels and tissues. Not designed to dissolve.
  • Old pills. Pharmacies accept them for safe disposal.

The word on a package does not change what happens inside a four-inch pipe.

Basement and laundry

Paint, solvents, drywall mud and grout all harden in drain lines or harm water treatment. Lint from washing machines builds up in laundry drains; a lint trap on the discharge hose helps.

Simple habits

  1. Strainers in every sink and tub.
  2. A grease jar by the stove.
  3. A small bin in each bathroom.
  4. Hot water after greasy dishes.

If a drain is already slow, see drain cleaning or call (365) 387-8531.

Stop and call a plumber if

  • Sour or sewer smell rising from a sink or floor drain
  • Grey water backing into the floor drain on laundry day
  • Plunging clears it for a week, then it slows again

Common questions

Do flushable wipes truly cause trouble?

They do. Municipalities across Ontario have pointed to wipes as a major cause of sewer and pump blockages.
