First: stop it overflowing

Reach behind the toilet and turn the shut-off valve clockwise until it stops. If there is no valve or it is seized, lift the tank lid and push the flapper down to seal it. This buys you time and prevents most of the damage.

Then work out which problem you have

The bowl fills up and drains slowly — blockage in the toilet or the line. The bowl does not fill and nothing happens — a tank problem. The flush is weak but it clears — mineral build-up or a partial restriction.

If it is a tank problem

Lift the lid. Is there water in the tank? If not, the supply valve is closed or the fill valve has failed. If there is water but nothing happens when you push the handle, the chain from the handle to the flapper has come off or broken — a two-minute fix. If the tank fills painfully slowly, the fill valve is failing. All of these are inexpensive parts.

If it is a blockage

Use a flange plunger, not a cup plunger. The flange is the rubber sleeve that extends into the trapway — a cup plunger designed for sinks will not seal on a toilet and will not generate the force.

Make sure there is enough water in the bowl to cover the plunger head. Plunging air does nothing.

Push down gently first to expel air, then pump firmly 15–20 times keeping the seal. The pull stroke does as much work as the push.

If plunging fails, try a closet auger — the short, sheathed toilet-specific one. Do not use a regular drain snake: it will scratch or crack the porcelain.

Three signs to stop and call immediately

Other fixtures are affected too. If plunging the toilet makes the tub gurgle or water rise in the shower, the blockage is in your main sewer line and plunging makes it worse.

Water is coming up somewhere else — a floor drain, a laundry tub. That is a main line backup and it is an emergency.

You know something solid went down there — a toy, a toothbrush, a phone. Plunging pushes it further into the trapway. That toilet needs to come off.

What we do

Porcelain-safe closet augering, foreign-object retrieval, and where something is genuinely lodged in the trapway we pull the toilet, clear it, and reset it on a fresh wax ring with a proper leak and level test. If the auger tells us the blockage is downstream, we move straight to the branch or main line. And if you have one bathroom, or you are a restaurant with customers waiting, this is an emergency call and we treat it as one — 24/7.

When to call a pro

If plunging and augering have not cleared it, or if any of the three emergency signs apply, call +1 (204) 399-4413. We serve Winnipeg, Selkirk, Steinbach, and everywhere within 100 km, 24/7.

Frequently Asked Questions

Will hot water and dish soap clear a toilet blockage?

Sometimes on a soft paper clog. Use hot, not boiling — boiling water can crack porcelain. It will not work on a solid object or a compacted blockage.

Are "flushable" wipes actually flushable?

They pass through the toilet and then do not break down. They are a leading cause of blockages in both homes and municipal systems. Do not flush them.

My toilet flushes weakly but clears. What causes that?

Usually mineral build-up in the rim jets and siphon holes, common with hard Manitoba water. It can be descaled without replacing the toilet.

When should I stop plunging and call a plumber?

Stop immediately if other fixtures are affected, if water is coming up somewhere else, or if you know something solid went down. Plunging in those situations makes things worse.
