Dual-Filtered Diaphragm Assembly

Royal Flushometer & Dual-Filtered Diaphragm Assembly Diagram

Available in diaphragm only and Royal Performance Kits. Royal Performance Kit includes dual filtered diaphragm assembly, handle repair kit with triple seal packing, high back pressure vacuum breaker repair kit, and one tailpiece O-ring. Diaphragm Only KIT contains drop-in dual filtered diaphragm assembly ONLY.

The dual filtered diaphragm can be used in Royal, Regal, and similar diaphragm-style valve bodies. For use in Sloan valve bodies with a bell-shaped cover (manufactured before 1964), replace the bottom filter ring in these kits with a blue A-108 Filter Ring.

Note the smaller of the two diagrams: the colors of the relief valve and the refill head plus the shape of flow ring identify the flush volume of a Dual-Filtered Diaphragm Assembly.

NOTE: In January 1998, the Royal diaphragm design was upgraded to a pre-assembled unit with two (2) plastic filtering rings attached to the rubber diaphragm (one on top and one on bottom). If the flushometer you are servicing has our older, segmented diaphragm with brass by-pass hole, refer to our Regal section for additional troubleshooting information.

† Consult factory for availability of replacement plastic relief valves (green, black, blue, and white) and brass relief valves.
NOTE: For older water closets that require 4.5 gpf (17.0 Lpf), choose kits A-1102-A or A-1038-A, but remove the flow ring before use. For blowout-style urinals that require 3.5 gpf (13.2 Lpf), choose kits A-1102-A or A-1038-A. For service sinks that require 6.5 gpf (24.6 Lpf), order A-36-A diaphragm repair kit (not shown Sloan Code No. 3301036) and remove the flow ring before use. Regulations for low consumption fixtures prohibit the use of higher flush volumes.
*Closet refill heads (gray) have larger slots than urinal refill Heads (black).
** Water Saver (3.5 gpf closet and 1.5 gpf urinal) and Low Consumption (1.6 gpf closet and 1.0 gpf urinal) fixtures must use matching gpf (Lpf) diaphragm kits; using a smaller gpf (Lpf) kit in fixtures not intended for less volume will result in inadequate dilution in urinals and improper evacuation in closets.
