a ROMAC “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 place. Should the Contractor elect to use this
type of fitting the submittal must include an evaluation of the existing pipe
wall thickness and provide cut sheets from the manufacturer showing this
type of fitting will achieve the desired results.
