Stinky drains? Here’s how to make them smell sweet again

Smelly sinks are a common household nuisance. Josh Stein spells out some simple steps to help solve the problem.

If your bathroom or kitchen sink smells of rotten eggs or sewage, you're not alone. It's a common problem but one which can get out of hand.

So what causes the stench? It could be down to something as simple as a bacteria build up. This is most common in kitchens, where rotting food or cooking oil that's been flushed down the sink can get trapped in the pipes. In bathrooms, hair might be washed down the plughole, which could result in a blockage and eventually cause a smell.
