Its role is to create an effective barrier to any return of water flow coming from the sewerage system during any possible overload event. The non-return valve is equipped with a stainless steel plate that pivots in the direction of the water flow from the building to the sewer system. In the case of an ebb, the plate closes mechanically with the thrust of the water. The plate, acting on a special lever, can be permanently hermetically locked. The non-return valve is foreseen during the design and sizing of the building drainage system according to UNI 12056-3. Furthermore, its use is absolutely recommended in existing buildings, where it is possible to intervene on the connection piping to the sewer network and there is the physical space to create a pit that houses the valve. The non-return valve must be approved in accordance with the European standard EN 13564-1: 2003 which guarantees its requirements, such as: effective flow, non-deformability, resistance, hydraulic seal, compliance of connection, correct opening \/ closing operation.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-574ff60 product-content-box elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"574ff60\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t\t\t<div class=\"elementor-row\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-ec08a18 product-box-right\" data-id=\"ec08a18\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-column-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t<div class=\"elementor-widget-wrap\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-6626431 elementor-widget elementor-widget-image\" data-id=\"6626431\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-image\">\n\t\t\t\t\t\t\t\t\t\t\t\t<img width=\"2297\" height=\"1455\" src=\"https:\/\/www.bampi.it\/en\/wp-content\/uploads\/sites\/3\/2020\/12\/V3_Indicazioni_Installazione_Valvola_Antiriflusso_ENG.jpg\" class=\"attachment-full size-full\" alt=\"\" loading=\"lazy\" srcset=\"https:\/\/www.bampi.it\/en\/wp-content\/uploads\/sites\/3\/2020\/12\/V3_Indicazioni_Installazione_Valvola_Antiriflusso_ENG.jpg 2297w, https:\/\/www.bampi.it\/en\/wp-content\/uploads\/sites\/3\/2020\/12\/V3_Indicazioni_Installazione_Valvola_Antiriflusso_ENG-300x190.jpg 300w, https:\/\/www.bampi.it\/en\/wp-content\/uploads\/sites\/3\/2020\/12\/V3_Indicazioni_Installazione_Valvola_Antiriflusso_ENG-1024x649.jpg 1024w, https:\/\/www.bampi.it\/en\/wp-content\/uploads\/sites\/3\/2020\/12\/V3_Indicazioni_Installazione_Valvola_Antiriflusso_ENG-768x486.jpg 768w, https:\/\/www.bampi.it\/en\/wp-content\/uploads\/sites\/3\/2020\/12\/V3_Indicazioni_Installazione_Valvola_Antiriflusso_ENG-1536x973.jpg 1536w, https:\/\/www.bampi.it\/en\/wp-content\/uploads\/sites\/3\/2020\/12\/V3_Indicazioni_Installazione_Valvola_Antiriflusso_ENG-2048x1297.jpg 2048w, https:\/\/www.bampi.it\/en\/wp-content\/uploads\/sites\/3\/2020\/12\/V3_Indicazioni_Installazione_Valvola_Antiriflusso_ENG-1200x760.jpg 1200w, https:\/\/www.bampi.it\/en\/wp-content\/uploads\/sites\/3\/2020\/12\/V3_Indicazioni_Installazione_Valvola_Antiriflusso_ENG-1980x1254.jpg 1980w, https:\/\/www.bampi.it\/en\/wp-content\/uploads\/sites\/3\/2020\/12\/V3_Indicazioni_Installazione_Valvola_Antiriflusso_ENG-600x380.jpg 600w\" sizes=\"(max-width: 2297px) 100vw, 2297px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p><span style=\"vertical-align: inherit;\"><span style=\"vertical-align: inherit;\">We could blame it on climate change or on the \u201cirresponsibility\u201d of men, but it is a fact that more and more often, the rains that hit our country cause considerable problems of flooding in buildings. The sudden and massive fall of several millimeters of water does not find a correct outlet and this generates water returns inside the buildings. Very often, despite the knowledge of the reasons that cause these problems, it is not possible to radically intervene on the sewer network and, therefore, it becomes necessary to adopt a solution directly on the building to be protected from flooding risks.
