11 May 2021

The method that is adopted by the plumbers to unclog a bathroom sink depends on what kind of clogging has occurred. One can flush the clog with baking soda and vinegar if it is just soap deposits. While plunging or tweezing works better when the clog is formed by hair. So, it is very crucial to figure out which is the best way of unclogging the drain after inspecting the drain clogging problem thoroughly.


 Why is a Bathroom Sink Usually Get Clogged? 

Here are the major reasons why the bathroom drains get clogged:

  • Hair clumps – When clumps of hair enter the drain of the bathroom sink, this gets struck on components of the drain or the walls of the drain. The usage of the zip-it tools or tweezing removes the hair from the clogged drain very well. In case any of these ceases to work, then the plumber dissembles the entire drain.
  • The solid object struck in the p-trap – The p-trap is the curving pipe that lies below the bathroom sink and connects directly to the pipe in the wall. In case any solid object falls down the drain, this might end up getting stuck in the p-trap. In such a case, the plumber will remove this unwanted object and then clean the p-trap.
  • Scum of soap – Scum of soap can be built up in the drain pipes over the course of time. Pouring one pot full of boiling water in the drain or even using vinegar and baking soda will help in clearing the drain in this case. You can plunge pouring some warm water and the drain would be cleared.
  • Damaged pipes – Corrosion, rust and several kinds of common types of pipe damage can potentially lead to clogging the bathroom drain eventually. The plumber, in this case, can replace the rusted pipes at the earliest. They can also adopt special ways like snaking or plunging them and this may help in clearing the drain temporarily.
