[TR] PDWA valve

[jerryvv at roadrunner.com (Jerry Van Vlack)]

List,

Does the switch on the top of the PDWA valve (TR6 and 250 and others I guess) 
have any type of seal between it (the plastic switch) and the brass PDWA 
housing? No apparent seal from what I see in the TRF TR6 Parts Manual, although 
the drawing of the switch would seem to show a seal of some type. No separate 
listing for a seal is shown.

Thanks,
JVV
