The complete A.W.S. valve is disassembled, cleaned and all new rubber is
installed on the spool assembly. The main spring and circlip is kept
unless worn or corroded. Similarly, the poppet, poppet spring and nut
are only replaced if need be.

The rebuilt A.W.S. valve is supplied with a pair of 90
degree street elbows to allow plumbing of the valve from below. The
outlet is fitted with a flow control needle valve that allows fine
control of the amount of water fed to the toilet, especially during
extended flush cycles.

| A Buna-N rubber kit containing all of the o-rings needed to rebuild one A.W.S. valve spool, one pushbutton, one air cylinder and the flapper crank in the ejection chamber is available. See the Parts List for this kit and the other rubber that you will need to completely rebuild a Microphor toilet. |

After valves and other assemblies are rebuilt, the equipment used in
calibrating F.R.L. assemblies, to the proper Microphor system pressure of
63 p.s.i., includes a 100 p.s.i. contractor's air gauge. A hose with a
standard quick connect at one end is used to supply air to either the
F.R.L. or a rebuilt pushbutton, which is in turn connected to an A.W.S.
valve for testing. Both the gauge and supply hoses have air-conditioning
style knurled connectors for rapid attachment to the 1/4" flare connectors
commonly employed on the air supply lines of toilet systems.
