Overflow Ring - Stainless steel
Overflow ring for installation in roof outlets with diameters from Ø75 to Ø160 mm.
An overflow ring is installed when the roof outlet is used as safety/overflow outlet. The ring is reversible, so the water level can be 25 or 35 mm when the drainage starts.
Note that small amounts of water may enter the roof outlet even though rainwater has not reached the predefined overflow level. Small leaks may appear due to to inaccuracies or foreign elements between the O-ring and the roof outlet's inner surface. If a completely watertight connection is required JUAL recommends applying an MS sealer on the adjoining surfaces.
