4. Option B: Install Using Oakum and Lead
WARNING: Risk of personal injury. An explosion can occur
if moisture comes in direct contact with molten lead. Pre-heat
wet or cold lead on the side of the furnace before adding it to
a pot containing molten lead. Dry the shower fixture, drain
pipe, and all shower drain components before installing the
drain fitting over the drain pipe.
Gather the materials and prepare the site for lead caulking.
Begin melting the lead. Use enough lead to ensure that the joint
can be filled in one pour.
While the lead is melting, yarn and pack oakum into the gap
between the drain pipe and the strainer body to a depth of
1-5/16" (3.3 cm) from the top of the strainer body [5/8" (1.6 cm)
thickness].
Eliminate all loose oakum fibers by packing them into the joint
with a yarning iron or packing iron heated in the molten lead pot.
Pour the molten lead into the joint to the top of the pipe in one
pour. Allow the lead to cool.
With the caulking hammer and the inside caulking iron, drive
down the lead in four places to set the joint.
Move the inside caulking iron slowly around the joint and pound
it with the caulking hammer to thoroughly caulk the inside edge.
With the outside caulking iron, work slowly around the joint with
the caulking hammer to thoroughly caulk the outside edge.
