The 1 ½'' hydraulic safety valve in the drain is specially designed for installation in the drain outlet of an automatic selector valve on a pool sand filter. Using it prevents water loss when the valve changes its working position or when the electricity flow fails and the valve remains in a position in which it could empty the pool. Using it is recommended in installations with SYSTEM VRAC multiport valves.
