Repair Parts shown in
bold face (darker)
type are more likely to need replacement
after extended periods of normal use. They
are readily available from most Warren
Rupp distributors. The pump owner may
prefer to maintain a limited inventory of
these parts in his own stock to reduce re-
pair downtime to a minimum.
IMPORTANT:
When ordering repair parts
always furnish pump model number, serial
number and type number.
