After each watering it lets the water drain out of the buried pipe, so there's no water left inside to freeze and crack the pipe or fittings in winter. It's part of Claber's Rain Jet range for underground systems.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow it works\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFit the valve at the lowest point of the buried pipe, pointing downwards, ideally into a small pocket of gravel so the water can soak away. While the system is running, the water pressure keeps the valve closed and watertight. When the zone switches off and the pressure drops, the valve opens and the pipe drains automatically.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy it works well\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIt drains the system automatically, so there's nothing to remember before the first frost.\u003c\/li\u003e\n\u003cli\u003eIt stays watertight while the system is watering.\u003c\/li\u003e\n\u003cli\u003eThe metal parts are bronze, so it won't corrode underground.\u003c\/li\u003e\n\u003cli\u003eIt's supplied with a 3\/4\" adaptor, so it suits both 1\/2\" and 3\/4\" fittings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e automatic draining of underground irrigation pipes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e 1\/2\" (15–21mm) male thread, with a 3\/4\" (20–27mm) adaptor supplied.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterials:\u003c\/strong\u003e bronze metal parts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack:\u003c\/strong\u003e 1 valve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClaber code:\u003c\/strong\u003e 90910.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eUse it with\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/collections\/claber-pop-up-sprinklers\"\u003eClaber pop-up sprinklers\u003c\/a\u003e and Colibri lawn kits.\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/collections\/solenoid-valves-manifolds\"\u003eSolenoid valves and manifolds\u003c\/a\u003e for multi-zone lawn systems.\u003c\/li\u003e\n\u003cli\u003eOur \u003ca href=\"\/pages\/lawn-popup-sprinkler-design\"\u003elawn pop-up sprinkler designer\u003c\/a\u003e to plan your system.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eAs an Authorised Claber Stockist, we hold Claber spare parts and we're happy to help you plan your system.
