Watts 794091 – Frequently Asked Questions
1) Which backflow preventers does the Watts 794091 repair kit fit?
The 794091 rubber parts kit is built for Watts 909 and LF909 reduced pressure zone assemblies in the 6 inch (150 mm) size. It will not service other Watts sizes or other series, so confirm the body tag reads 909 or LF909 and 6 inch before ordering.
2) What parts come in the Watts 794091 6 inch 909 repair kit?
It is a complete rubber parts kit: upper and lower check stem O-rings, check disc, cover O-ring, sleeve O-ring, piston O-ring, relief valve disc assembly, diaphragm, piston seal, and lubricant. That covers the soft goods a tester typically replaces after a failed annual test.
3) What is the difference between a rubber repair kit and a full rebuild kit for a 6 inch RPZ?
A rubber kit like the Watts 794091 replaces only the elastic wear items, the O-rings, check disc, RV disc assembly, diaphragm and piston seal. A full rebuild adds the metal check modules, springs and seats. If the test failed on a leaking check or a weeping relief valve and the seats are clean and unscored, the rubber kit is the correct call; if the seats are pitted or the springs are corroded, you need more than this.
4) Can I use the 794091 kit on a lead free LF909 and on an older 909?
Yes, the same kit serves both. Watts lists it for the 909 and the LF909 in 6 inch, so a facility running a mix of older bronze 909s and newer lead free LF909s of that size can stock one rubber kit for both.
