NOTE: Special points pertaining to orifice and orifice gasket reassembly
Follow the steps below when inserting the orifice into the body in order to ensure that
the gasket does not fall off and is inserted correctly without protruding from the
groove.
1. First, insert the orifice alone into the orifice-housing section of the body, in order
to ascertain how much of it should be sticking out.
2. Take the orifice out again, and then fill the groove in the orifice with water and
insert the gasket. The surface tension of the water will now hold the gasket in
place, and it will not fall out even if the orifice is pointed downwards.
3. Without altering anything, insert it into the orifice-housing section of the body and
check to make sure that the amount of orifice sticking out of the body is the same
as the amount that was sticking out when only the orifice was inserted in step 1.
4. Hold it in that position by hand and, after hand-tightening the orifice locknut from
the outlet side, hold the orifice in place from the body float chamber side using a
drive wrench and then tighten the orifice locknut to the proper torque using a
torque wrench.
