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-ring to facilitate
insertion.
Check valve may be taken apart and
cleaned in between maintenance to remove
particles.
CAUTION: Parts may contain

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