A blockage in the drainage system of a home can occur at multiple points: in the branch line, in the main house drain, or in the connection to the sewer.
These three simple tools can be used to unblock common types of obstructions, although it is wise to contact a plumbing professional if one has any doubts.
For blocked toilets and sinks, use a plunger to unclog the blockage. Use petroleum jelly to coat the rim of the cup before applying the plunger. Use short, rapid strokes to unblock the drain and repeat if necessary.
A drain-and-tap auger is another useful tool for unblocking drains. Remove the strainer or pop-up stopper and feed the auger into the drain. After the blockage or debris has been loosened, use hot water and detergent to clean out the drain, recommended Rooter2.
If the clogged area has a clean-out plug, remove the plug and use a bucket to catch the water as it drains out. Then use a straightened wire coat hanger or an auger to dislodge the blockage.
