Description

Here we have a Flushmate 504 series pressure assist flush valve, we got them when we were experimenting on how to make our (now defunct) Lydia toilet to work on extremely low gallonage.  These flush valves use 1.0 gallons per flush and are the M101526-F4 model.  This model has been replaced by the F42 model.  They will work with the following brands/models

Mansfield 153 , St Thomas/Vitromex, Peerless 1, Sloan ST-8016 and ST-8116, Vitra 5066, and Western T4ULF-PF-1

Two available, still on the original boxes.
