Drain problems are often overlooked when we are trying to solve the problem of a clogged or slow draining bathroom sink. We often think that just getting a plunger and plunging down on the drain will fix the problem. But drains can be clogged up from different sources, from hair to soap scum, which require professional drainage services. One way to tell if your drain needs to be replaced is if you start noticing a bad smell coming from your bathroom and no matter how many times you plunge down it doesn’t go away. The other telltale sign is noticing your water bill going up in price because of how much water is being used by the drain clog.
