We recommend cleaning all parts with warm
soapy water and a toothbrush before
installing the new parts.
Water normally lubricates the parts, but
you may use silicone on the o-rings to
facilitate insertion.

concentrated chemicals. The use of
Proper Protective Equipment is recom-
mended when performing maintenance.
