On my 61 I have not noticed any packing material, only an O ring. Is
it missing? or did this valve go thru a development period? There is
a groove for the o ring. Careful adjustment of the 4 screws that
hold the valve together adjusts the tension on the O ring so the
valve pulls easily. It does not leak as long as the valve is fully
opened or closed. I have not seen an obvious place for packing.
I removed the huge Iron fitting from below the valve and replaced it
with a plastic fitting for the sewer hose. Both gray water lines
have been re routed to a grid made of 3 inch sewer pipe which has its
own valtera valve ( along with another secret outlet under the
trailer) The sewage and. gray water are now 2 seperate
systems. Getting rid of the big iron fitting increased the ground
clearance quite a bit
