Inspecting Parts
Plastic parts: examine for cracking, softening or
discoloring. This may indicate chemical attack of the
material. Defective parts must be replaced. Alternate
material may be required. Contact your supplier or
Pentair Water for assistance.
Metal parts: check for corrosion, scratches, dents,
cracks or other damages to insert ring and spiral
retaining ring.
Other parts: examine for any damage, such as
gouges, chips or cracks, that could affect structural
strength or sealing characteristics. The following are
some examples of defects that may require replace-
ment of the affected part.
End Plug: crac ked, disc olor ed, seal ing
areas damaged(chipped or gouged), threads
stripped or cross-threaded.
Spiral Retaining rings: are the sole means of
end plug retention. Parts bent, corroded,
cracked or damaged in any way must not be
used. Carefully check for hairline cracks.
Refurbishing Shell

deposits from locking ring groove in the shell.
2. Using a medium or finer grade of ScotchBrite
