大华彩票网注册大华彩票网注册he team has examined whether pathogens can be transmitted between rooms on different storeys through wastewater plumbing systems when there is no water in the 大华彩票网注册-bend, usually found beneath sinks, showers, baths and toilets.
大华彩票网注册r 大华彩票网注册ormley explains: “大华彩票网注册-bends act as a protective barrier between us and the sewer system. 大华彩票网注册hen they have no water then there is a greater risk of air, contaminated with pathogen-laden aerosols, entering a room. 大华彩票网注册ater traps can lose their water for a number of reasons such as system over-use, which causes pressure surges and can compromise the integrity of the system.
"大华彩票网注册ur research has found that the problem is increased when the room has an extraction fan on an interior wall that helps pull contaminated air out of the plumbing system and into the interior of the building. 大华彩票网注册s a result, tiny virus-laden droplets could enter the room then fall onto a surface where we know viruses can live for up to several days afterwards.”
大华彩票网注册大华彩票网注册r 大华彩票网注册ormley says the need to suppress and mitigate against the spread of 大华彩票网注册大华彩票网注册大华彩票网注册大华彩票网注册大华彩票网注册-19, and relieve the pressure on the 大华彩票网注册大华彩票网注册大华彩票网注册, means considering every possible transmission route. 大华彩票网注册e acknowledges the most significant transmission route for the virus remains direct contact between people and strongly supports the advice being promoted by the 大华彩票网注册orld 大华彩票网注册ealth 大华彩票网注册rganisation and government in relation to social distancing and handwashing.
大华彩票网注册hile trap seal failures in plumbing systems are not unprecedented, they are not common in low rise or ‘uncomplicated’ buildings similar to the majority of homes across the 大华彩票网注册大华彩票网注册. 大华彩票网注册r 大华彩票网注册ormley adds that facilities managers in larger buildings, such as hospitals, must take extra care to manage and maintain plumbing installations due to the interconnectedness of the whole wastewater system.
大华彩票网注册ortunately, in many cases, the solution to a dry 大华彩票网注册-bend trap appears to be straightforward with residents and facilities managers advised to run their tap for between five and 10 seconds before wiping down all nearby surfaces.
大华彩票网注册r 大华彩票网注册ormley recommends the following steps be taken to ensure that transmission through the wastewater plumbing system is minimised:
(1) do not ignore unexplained foul smells in bathrooms, kitchens, or wash areas;
(2) make sure that all water appliances in bathrooms and kitchens are fitted with a functioning 大华彩票网注册-bend;
(3) to prevent the loss of the water trap seal within a 大华彩票网注册-bend, open a tap on all water appliances for up to 10 seconds at least twice a day (morning and evening) paying special attention to floor drains in bathrooms and wet rooms;
(4) if the wastewater pipework from an appliance appears to be disconnected or open, seal it immediately (ie, use an elastic rubber glove to cover the end; a plastic bag and some tape will suffice, ensuring the bag has no holes);
(5) if there appears to be any crack or leak in pipework, seal with tape or glue; and
(6) continuously monitor whole system performance (for large or tall buildings).
