1.
Thoroughly clean the bell and spigot ends, making sure they are free of
mud and grit. Remove the protective shrink-wrap from the gasket. If the
gasket has been removed, make sure the gasket seat is clean and
reinstall the gasket by stretching it over the pipe and nesting it in
the seat. Gaskets should be installed with the marking facing the
coupler.
2. Remove shipping collars (where provided) prior
to
lowering the pipe in the trench. Properly dispose of shipping collars
outside the pipe trench. Do not install pipe with shipping collars on
the pipe and do not dispose of shipping collars in the trench.
3. Lubricant is supplied for gasketed joint
installation in either buckets or spray lubricant. The lubricant should
be liberally applied to both the bell and spigot ends of the pipe. Care
should be taken to ensure lubricant is applied to the chamfered leading
edge of the bell.
4. Align the pipe and push the spigot home on
grade.
Joints should be installed with bells facing upstream for proper
installation. Generally, pipes should be laid starting at the
downstream end and working upstream. Small diameter pipe (below 24")
can usually be installed by pushing the joint home by hand. Larger
diameters may necessitate using a bar or equipment to push home. If a
bar or equipment is utilized a wood block should be used to prevent
damage to the bell. When pushing the joint home, make sure bedding
material is not pulled into the bell by the spigot. Material such as
small stones and sand pulled into the bell as the pipe is joined can
cause leaks.
