In the worst case, the septic tank can break. The VRF valve opens automatically if the vacuum becomes too high. When open, the free flow is more than 1100 m2. The valve meets ISO8099 requirements. The tank must have a \u00d8 56 mm hole for installation. The VRF low pressure valve is strongly recommended if the diameter of the existing drain valve is less than 19 mm and less than 38 mm for tanks over 400 litres.<\/p>","protected":false},"excerpt":{"rendered":"<p>Vetus septic tanks<\/p>","protected":false},"featured_media":18337,"template":"","meta":{"_seopress_robots_primary_cat":"","_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":""},"product_brand":[],"product_cat":[180062],"product_tag":[],"class_list":{"0":"post-122994","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-jatevesi-septijarjestelmat-wc","8":"first","9":"onbackorder","10":"taxable","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"exclude_global_add_ons":[],"addons":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v24.2 (Yoast SEO v26.5) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Septitankin alipaineventtiili \u00d8 56 mm - Mepratuote venetarvikkeet<\/title>\n<meta name=\"description\" content=\"Venetarvikekauppaa vuodesta 1971 myym\u00e4l\u00e4ss\u00e4 ja verkossa.
