SHARKBITE
®
BURIAL
SharkBite Universal fittings are suitable for burial in
most applications; however care is required when
using fittings in applications that require burial to
ensure the correct installation practices are used and
due care is given to any environmental factors that
may have a detrimental eect on the life expectancy
of the fittings and pipe.
The installation of SharkBite Universal fittings
in applications that will require the burial of the
fitting must comply with all local plumbing code
requirements.
SharkBite Universal fittings and SharkBite PEX are
not suitable for use in areas where the soil is or may
become contaminated* including the soil used for
back filling. All SharkBite Universal fittings with brass
bodies must have an impervious barrier between
the fitting and the surrounding soil. Self-fusing,
formaldehyde and chloride-free, fully cured silicone
tape with a minimum thickness of 0.020" should be
used for this purpose.
The soil used for back filling must be free of rocks,
debris or any sharp objects that may cause damage
to the fitting or pipe through impact or abrasion.
* Examples of contamination include, but are not limited to, petrochemicals
(reclaimed service station sites), high levels of nitrogen compounds (this could
be caused by animal waste or fertilizer that may be found in some agricultural
applications), low pH levels (below pH 6), high pH levels(above pH 8), run o
from land fill, formaldehyde compounds, and solvents. It should be noted that
such contaminants have been known to migrate through plastic piping systems
and contaminate the Potable water supplied through these pipes.
SHARKBITE SILICONE BURIAL WRAP
Make a SharkBite Universal connection ensuring
pipe is inserted to proper depth. While leaving the
protective film in place, measure the amount of tape
needed to completely wrap the fitting. To ensure a
proper seal, overlap tape by 1"past the end of the
fitting on every end and 1/4" – 1/2" between/across
the fitting. Wrap the fitting by pulling the tape tight
and removing the protective film. Completely cover
the fitting. The tape will bond to itself within minutes
and will cement to itself within a few hours forming
an air and water tight seal.
SHARKBITE FITTINGS IN CONCRETE
Do not allow joints within the slab. Use a continuous
length of SharkBite PEX Pipe within the slab and be
sure to check for leaks before pouring concrete.
SHARKBITE DISTANCE BETWEEN FITTINGS
Allow at least 1" of spacing between SharkBite
Universal fittings for removal purposes.
SHARKBITE GROUNDING ON COPPER PIPE
When connecting a SharkBite Universal fitting to a
copper piping system, install a copper jumper cable to
ensure proper grounding. SharkBite Universal fittings
are not an electrically continuous fitting.
