PART 2 - PRODUCTS
A. Products for attaching to existing sewer manholes are described in Sections 02631 (Precast
Manholes and Catch Basins) and Section 01735 (Cutting, Coring and Patching)
B. Products for attaching sewer service lines or drain lines to existing sewer mains (that have
been CIPP lined for this project):
1. Connection of new sewer service or drain pipe to existing sewer mains shall be by
mechanical saddles (as described in ttems 2 and 3 below). The connection device shall
provide a firm base that will hold and attach the service main to the existing pipe
without the possibility of the pipe becoming loose or detaching from the main. Putting
the pipe in the main and grouting around it will not be allowed.
2. Where feasible and sizing allows this type of connection, the preferred method of
attachment of PVC service or drain pipe to the existing main 1s by aROMAC “CB”
Sewer Saddles or equal.
3. Should the ROMAC type service connection not be feasible due to pipe size or other
constraints, the connection may be made using a Kor-N-Tee, Inserta Tee or equal.
These types of fittings rely on having enough of the pipe wall thickness present to
create tension between the fittings the pipe wall such that fitting will be held securely in
