Insert a pry bar into the inlet of the valve and lift up the bottom of the stem. Lift the
stem to ensure that the diaphragm does not fray against the threads of the studs
while seating the diaphragm. Gently slide the diaphragm stud holes over the studs.
Ensure not to fray or twist the inner diameter of the diaphragm stud holes. Ensure
this is done while the stem is lifted. This may require additional assistance.
If the valve is installed in the piping, manually hold the valve stem assembly so that
the diaphragm uniformly slides over the studs.
