Reversed bottom drain 50MM – Easy to install – Aquaforte

Description du produit : Very convenient way to equip ponds without a bottom drain with a bottom outlet using a 50 mm pipe! Equipped with a special 50mm elbow with a 32mm hole for bleeding to prevent vacuum from being present in the system. The hole can be used with 32mm tube or 25mm pipe (a reducing nipple to 25mm is supplied as standard). The bottom drain has a PE bottom plate so that it cannot attach to the sheet by suction. Comes with a bag of gravel for ballast.
