There are many reasons for clogged drain. In the bathroom
drain clogs result when dirt, skin flakes, and especially hair binds to soap
scum on the walls of drain pipes and in the kitchen sink drains clog when
cooking grease or oil cake onto drain pipe walls. http://www.rrservicesllc.com/
It depends on which sink. In the kitchen, it is usually some type of food from previous meals or small peices of trash. In the bathroom, the usual culprit is hair from shaving and again, possible small peices of trash. Good luck to you.
My wife and I moved into a bigger apartment recently. Did you know that?
