Clogged Toilet Bowl: How to Unclog It and When to Call a Plumber

From $94.76 fixed price4.9 from 136 Google reviewsSame-day slots

A clogged toilet bowl, or toilet choke, is one of the most common plumbing problems in Singapore homes. The water rises instead of draining, drains very slowly, or gurgles when you flush. Most chokes are caused by too much toilet paper or by wet wipes and other items that do not break down.

What's Included

  • Clearing the blockage in the toilet bowl and its outlet

  • Replacing a faulty flush system or siphon, if a weak flush is causing repeat chokes
  • Installing a new toilet bowl set, if the bowl is cracked or needs replacing

How to Unclog a Toilet Safely

  1. 1Stop flushing. Each flush adds water and can make the bowl overflow.
  2. 2If the water is high, wait 10 to 15 minutes for it to drain down a little, and lay old towels around the base.
  3. 3Use a flange plunger, the kind with a soft extension that fits the toilet outlet. Seal it over the hole and push and pull firmly 10 to 15 times without breaking the seal.
  4. 4If the water starts to drain, flush once to check. Repeat the plunging if it is still slow.
  5. 5Avoid chemical drain cleaners in a fully blocked toilet. They can splash back, and they rarely clear a solid blockage.

Stop and call a plumber if

  • An object such as a toy, phone or sanitary product has gone down
  • Water rises from the floor trap or shower drain when you flush
  • Other drains in the flat are also slow or gurgling
  • Plunging has not worked after a few attempts

Common causes of a clogged toilet

  • Too much toilet paper flushed at once
  • Wet wipes, including "flushable" ones, which do not break down like toilet paper
  • Sanitary products, cotton buds and kitchen roll
  • Objects dropped in by children
  • A weak flush that does not clear the bowl, often a worn flush system or siphon

What Affects the Price

  • A simple blockage versus one that needs parts replaced
  • Whether the flush system or siphon is causing repeat blockages
  • Replacing the whole toilet bowl set costs more than clearing a choke

Clogged Toilet Bowl FAQs

StringsSG clears clogged toilet bowls from $94.76 at a fixed price. If a faulty flush system or siphon is causing repeat blockages, those repairs are listed separately in the table on this page. You see the total before you confirm.
Yes. Wet wipes, including many sold as flushable, do not break down the way toilet paper does, and they collect in the outlet and pipes. Put them in the bin instead.
Repeated chokes usually mean a weak flush that does not push waste through, a partial blockage further down the pipe, or regular flushing of wipes. A plumber can check the flush system and siphon as well as clearing the blockage.
A blockage in your own toilet bowl and the pipe leading from it is usually the owner's to fix. If the blockage is in the common sanitary stack shared by several flats, and neighbours are affected too, contact your Town Council.
