Clearing a blocked WC

Method

When the WC pan is flushed the water level should remain the same level. If the level rises and is slow to clear there is probably a partial blockage near the trap. Fill a bucket (or a bedroom bin) with water and empty into the pan, throwing it down as quickly as possible. Try this two or three times if necessary as this action will often clear the blockage.

If the blockage remains use a plunger. A Cooper’s plunger is the correct tool to use because it is a plain rubber disc - never use a plunger with a metal disc as it could damage the pan. If you do not have a plunger try using a household mop or toilet brush wrapped in some old rags to increase the diameter of the ‘plunger’ and then cover the end with a black plastic bag tied at the top.If the water level in the pan is high, use a container to bale out some of the water first or use a length of hose to siphon off the water. (Fill the length of hose with water and use your thumbs to seal both ends. Have a bucket ready next to the WC, then place one end of the hose under the water in the pan and the other end to a lower point in the bucket. The water will now run freely into the bucket). Insert the plunger in the pan and move it firmly up and down vigorously.

If this method fails try use a chemical drain cleaner or caustic soda, but you must follow the instructions carefully. However this method will take a long time to clear.

If this method fails try using a WC auger. Push the flexible clearing rod into the trap as far as possible. When the obstruction is found, the cranked handle at the other end is clamped and turned. Next either push or pull the rotating head when the blockage is engaged and then dislodge. Flush the pan and disinfect to clear any debris. Clean and disinfect the auger thoroughly.
