Unclogging a Bathroom Drain?
how to Unclogging a Bathroom Drain? we have 2 bathroom upstair and now if we used both of the bathroom the same time, the water may leak out somewhere from one of the bathroom floor. and when use one of the toilet, the other toilet will have some air bubbles keep coming out.
i tried the 2L liquid which i purchased from bunning which stated can discolve the hair, pour 1L into it and wait 2 hours, but still can't fix it.
anything can do ourself or should I just find a local plumber? i worry about the cost. thanks.
