SharkBite® Burial
SharkBite Universal ttings are suitable
for burial in most applications; however
care is required when using ttings 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 ttings and
pipe.
The installation of SharkBite Universal
ttings in applications that will require the
burial of the tting must comply with all
local plumbing code requirements.
SharkBite Universal ttings and SharkBite
PEX are not suitable for use in areas where
the soil is or may become contaminated*
including the soil used for back lling. All
SharkBite Universal ttings with brass
bodies must have an impervious barrier
between the tting 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 lling must be free
of rocks, debris or any sharp objects that
may cause damage to the tting 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 ll, 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 lm in place,
measure the amount of tape needed to
completely wrap the tting. To ensure a
proper seal, overlap tape by 1"past the
end of the tting on every end and 1/4"
– 1/2" between/across the tting. Wrap
the tting by pulling the tape tight and
removing the protective lm. Completely
cover the tting. 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 ttings 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 ttings for removal
purposes
SharkBite Grounding on Copper
Pipe
When connecting a SharkBite Universal
tting to a copper piping system, install
a copper jumper cable to ensure proper
grounding. SharkBite Universal ttings are
not an electrically continuous tting.
