3)PAN OUT ALL THE MAJOR FITTINGS WILL SIT AND ENSURE THE INSPECTION CHAMBER IS ALIGNED FOR THE WATER FLOW IS MAINTAINED THROUGH THE MAIN CHANNEL TO MINIMIZE ANY BLOCKAGE
4)IF FITTING TO A VERTICAL SOIL AND VENTILATION PIPE,A SOLID SUPPORT IS IMPORTANT AND PLACE IT UNDER THE LONG RADIUS REST BEND
5)MEASURE AND CUT THE LENGTH OF PIPE THAT JOINS THE REST BEND TO THE FIRST INSPECTION CHAMBER. ENSURE ALL CUT LENGTHS OF PIPE ARE SHELL PROOF TO ROUGHLY 45 DEGREE ANGLE
6)JOIN THE FIRST PIECE OF PIPE WITH A SPRAY OR GEL SILICONE LUBRICANT ON THE SEAL TO EASE FITTING.REPEAT THE PREVIOUS PROCEDURE FOR ALL THE REMAINING FITTINGS
7)TRAPS, MUFFLE GULLIES AND OTHER AVAILABLE FITTINGS CAN BE ADDED TO THE SYSTEM
8)SOIL AND VENTILATION PIPES CONNECT STRAIGHT INTO THE LONG RADIUS BEND. RAINWATER DOWNPIPE CONNECT TO THE SYSTEM VIA A UNIVERSAL RAINWATER ADAPTER
9)MINI ACCESS CHAMBERS CAN BE ADDED UP TO 600mm MAX HEIGHT. THE LARGE ACCESS CHAMBERS CAN BE UP TO 3m HIGH USING A 350mm REDUCED ACCESS FRAME AND LID. ADD RISES UNTIL THE REQUIRED DEPTH
