Slow drains can be extremely annoying, especially when you need to wait for what seems like ages before you can drain the sink after washing dishes or even just washing your hands. One of the best reasons to treat a slow drain problem right way is that slow drains can easily become clogged ones, at which point they are much harder to treat. First, try an environmentally “friendly” drain cleaner with bacteria and enzymes. We don’t recommend chemical drain cleaners for several reasons; most drain chemicals are very toxic in nature, not a good thing to keep around the home if you have children or pets, and the toxic chemicals can also have a negative effect on your piping as well. Also, over time these chemicals may deteriorate your pipes from the inside out. If this drain cleaner does not work you may need to have a plumber come clean out the drain.
