My drains smell but they aren't blocked
Smelly drains are a common problem. We don’t come out to look at these as it’s an easy problem to resolve yourself.
First, clean out the plug to make sure there is no food or other blockages in there, and try pouring some bleach or cleaning fluid down the sink, basin, bath or shower waste and the overflow.
This should sort the problem for you. If your water is draining slowly or you think there might be a blockage click here.
