It switches over to incoming mains water automatically, with no intervention needed, so the property keeps access to water in the event of a system failure.\u003c\/p\u003e\n\u003cp\u003eIn normal operation, the boosted supply pressure is higher than the mains pressure, which keeps the Double Check Valve closed. If the pump fails or is switched off, the system reverts to mains pressure. It is intended for domestic and light commercial use.\u003c\/p\u003e\n\u003cp\u003eConventional bypass arrangements are often associated with stagnant water or backflow hazards. The DPT Bypass Valve has a very small internal volume, and water movement on both sides (towards the cistern and from the pump) helps to ensure regular flushing. It can only be used in non-category 5 arrangements.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAutomatic switching to mains water if the booster pump fails\u003c\/li\u003e\n\u003cli\u003eEasy installation: can be fitted horizontally or vertically, with the inlet facing either side\u003c\/li\u003e\n\u003cli\u003eVery small internal volume, with flushing from both sides\u003c\/li\u003e\n\u003cli\u003eFour isolation valves for easy removal and cleaning of the check valve\u003c\/li\u003e\n\u003cli\u003eDZR brass body with brass valves and POM cartridges\u003c\/li\u003e\n\u003cli\u003eFemale BSP thread connections\u003c\/li\u003e\n\u003cli\u003eDomestic and light commercial use\u003c\/li\u003e\n\u003cli\u003eAvailable in six sizes from 1\/2\" to 2\"\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSizes available\u003c\/td\u003e\n\u003ctd\u003e1\/2\", 3\/4\", 1\", 1 1\/4\", 1 1\/2\", 2\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection\u003c\/td\u003e\n\u003ctd\u003eFemale BSP thread\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody\u003c\/td\u003e\n\u003ctd\u003eDZR brass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eValves\u003c\/td\u003e\n\u003ctd\u003eBrass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCartridges\u003c\/td\u003e\n\u003ctd\u003ePOM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum supply pressure\u003c\/td\u003e\n\u003ctd\u003e10 bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature\u003c\/td\u003e\n\u003ctd\u003e65 degrees\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuitable for\u003c\/td\u003e\n\u003ctd\u003eDomestic and light commercial use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eArrangement limit\u003c\/td\u003e\n\u003ctd\u003eNon-category 5 arrangements only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"DPT","offers":[{"title":"1\/2\" Bypass Valve Assembly","offer_id":59629338558789,"sku":"BPA1\/2","price":90.0,"currency_code":"GBP","in_stock":false},{"title":"3\/4\" Bypass Valve Assembly","offer_id":59629338591557,"sku":"BPA3\/4","price":150.0,"currency_code":"GBP","in_stock":false},{"title":"1\" Bypass Valve Assembly","offer_id":59629338624325,"sku":"BPA1","price":289.0,"currency_code":"GBP","in_stock":false},{"title":"1 1\/4\" Bypass Valve Assembly","offer_id":59629338657093,"sku":"BPA1.1\/4","price":425.0,"currency_code":"GBP","in_stock":false},{"title":"1 1\/2\" Bypass Valve Assembly","offer_id":59629338689861,"sku":"BPA1.1\/2","price":675.0,"currency_code":"GBP","in_stock":false},{"title":"2\" Bypass Valve Assembly","offer_id":59629338722629,"sku":"BPA2","price":889.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/4595\/6165\/files\/bypass_valve_assembly.png?v=1791456153","url":"https:\/\/tanks-direct.co.uk\/products\/automatic-bypass-valve-assembly","provider":"Tanks Direct","version":"1.0","type":"link"}
