10 SUtl1P penetrations sufficient length of primary pipe to accommodate both the closure pieces and the (comn , fiberglass bell x female threaded adapter which terminates the primary. To install 3 x 2 reducing closures,sand the sump fitting,the exterior of the primary pipe for about 1'/2 inches where the small end of the closure pieces will fit(Fig.10-4),and the bonding surfaces of the closure pieces(Fig.7-6).Apply liberal amounts of adhesive to the sanded areas and bolt the closure halves together. The containment system annular space can also be sealed off and isolated from the sump by means of special sump penetration fittings that permit direct connection of 11/2 or 2-inch flex 42 to 48- connectors to the Fig. Sand the bonding ftjBy otters inch riser 9 9 penetration fittings surfaces of the sump penetration fitting,the primary pipe,and the - themselves on the reducing closure pieces before _ inside of the sump. applying B20 adhesive.
