A slow sink drain is a very common plumbing problem. The bathroom sink is most frequently affected by this particular problem. There are several things that can contribute to a slow sink drain. Often the pop-up that is used to stop up the sink can collect a lot of hair and debris as the sink is used on a daily basis.
Also, soap and other products that are washed down the drain can slowly collect in the drain pipes. The build-up that naturally collects over time reduces the size of the drain effectively slowing the progress of draining water.
All of the things that cause a slow sink drain happen naturally over time and can not usually be avoided. The only thing to be done is to periodically clean the drain to keep it flowing . The first step to getting the sink drain flowing again is to clear out any hair and debris that has collected there.
One quite easy way to do this is to use the Zip-it tool.
This really inexpensive tool is one of my favorite tools because it works wonders in just minutes. The Zip-it tool can be put into the drain and it catches hair and debris which can then be pulled out. The Zip-it can be used in a sink drain with or without a pop-up because it is thin enough to fit in the drain even with a pop-up in place.
