Drain smells are very common during the summer because the hot weather can make bad odours worse, especially if there is a blockage or problem in any of the pipes. The good news is that these smells are usually easy to stop if the issue is dealt with early on.
Stagnant Water
Standing water can also create strong smells in summer. Warm temperatures can help bacteria grow more quickly, which can make drains smell worse. According to the Health and Safety Executive, bacteria grow faster in warm water, especially between 20°C and 45°C and this can be very dangerous to health.
Damaged Pipes
Sometimes bad smells are caused by damaged pipes. Cracks and leaks can happen as pipes get older, during freezing weather or when tree roots grow into them. These problems can also affect how well sinks and toilets drain. If the problem keeps coming back, a CCTV drain survey Birmingham, like the examples seen here, https://www.wilkinson-env.co.uk/drainage-services-cctv-surveys-midlands/cctv-drain-surveys/birmingham/ can help find hidden damage inside the drainage system before it gets any worse.
Food Going Down the Drain
One of the biggest causes of smelly drains is food waste. Small bits of food often get washed down the sink when cleaning plates, pans and cutlery and even tiny pieces like rice, eggshells or onion can build up inside pipes over time. In warm weather, this food starts to break down faster and can create unpleasant smells. Using a sink strainer or drain guard can help stop food from going down the drain and causing problems later on.
