Watts “Make Up” Spools are used when retrofitting a backflow
preventer into an installation where an existing backflow preventer is being replaced. Watts “Make Up” Flanges are used in
piping applications where there is a need for additional fitting
lay length. The W-SPL and W-FLG feature Lead Free* construction to comply with Lead Free* installation requirements.

How to order
Locate the manufacturer and model number under the valve size column in the matrix on these two pages. It is assumed that the
valve you will be installing is a Watts 774 Sentry Series. On the first line across from the model number is the lay length of the valve
less gates. On the lines listed below is the valve being replaced. On that line is the lay length of that valve. The column to the right
is the length of the spool needed to “make up” the difference between the valve being replaced and the lay length of the “Sentry
Series.” Below the spool length is the ordering code for that spool.
