Hydraulic safety valve in the drain
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.SKU: HS4886
