The flapper valve piston is rebuilt by disassembling and installing all new rubber into it. Buna-N rebuild kits are available containing all of the o-rings necessary to completly rebuild this valve plus all of the other o-rings needed to refurbish a single toilet. Photo by E. Wilde, 2002 Jan 24.

Once the piston and flapper actuator are rehabilitated, the ejection chamber is assembled with a new rubber seal and flapper seal and the air cylinder is reinstalled on its side. Don't forget extended cylinder length is 7-1/4", C-C. Photo by E. Wilde, 2002 Jan 24.

A view of something most people would rather not see. The large o-ring that seals the two halves of the chamber is easily visible (hint: make sure this one seals properly in the groove around the edge -- you don't want it to leak). Note that this flapper has not yet been drilled to accept the new style flapper gaskets. Photo by E. Wilde, 2002 Jan 24.

After a good long soak in a bucket of industrial cleaner and bleach, the ejection chamber is brushed clean, flushed out with clear water and then reassembled with a new o-ring and stainless bolts. Better than new! Don't forget to wear rubber gloves for this job! Photo by E. Wilde, 2002 Jan 24.
