I was struggling for a long time with debts and at the same time paying a lot on the maintenance of my house.My Kitchen sink was used to block many times and any time I called the plumber,the service fees was killing me.
One time my auntie told me to use any of these methods:
1.Put the One Shot and could be bought in any supermarket.
2.She told me to ask my husband if I can not undo the u-bend myself.However, she advised me to wear gloves and goggles.
4.She told me that I could also use caustic soda but I should wear long sleeves or rubber gloves.
5.Lastly she told me that I could pour a can of baking soda in plug hole and pour the white vinegar and when the foams start coming I should pour boiling water down the plug.
I have used One Shot and it works wonders for me.I have not tried other methods though.
