How to Unclog a Blocked Sink Drain with a Plunger One of the most common plumbing problems is a blocked sink drain. However, if your drain gets blocked, there’s no need to call out an emergency plumber as it’s actually one of the easiest problems to remedy yourself using a plunger.
You’ll find that a standard cup-style plunger with a shallow dome and a flat bottom rim is the best kind for unblocking sinks, so it makes sense to have one in your toolbox. How Plungers Work Plungers use the forces of suction and compression to clear the drain. By pulling up on the plunger, it pulls any water in the drain in an upward motion to help dislodge the blockage. As you push the plunger down, the water is forced in a downwards to move the blockage in the opposite direction. The constant push and pull effect will eventually break up the obstruction so that it’s carried away down the drain by the water. How to Free the Blockage In addition to a plunger, an emergency plumber in Port Stephens recommends that you also keep a set of needle-nose pliers or a coat hanger and some old rags close to hand when you start the unblocking process.
