other than at Liberty Pumps or its authorized service centers, automatically voids warranty.
Liberty Pumps, Inc. warrants that pumps of its manufacture are free from all factory defects in material and workmanship
for a period of 3 years from the date of purchase. The date of purchase shall be determined by a dated sales receipt
noting the model and serial number of the pump. The dated sales receipt must accompany the returned pump if the date
of return is more than 3 years from the "CODE" (date of manufacture) number noted on the pump nameplate.
The manufacturer's obligation under this Warranty shall be limited to the repair or replacement of any parts found by the
manufacturer to be defective, provided the part or assembly is returned freight prepaid to the manufacturer or its
authorized service center, and provided that none of the following warranty-voiding characteristics are evident.
The manufacturer shall not be liable under this Warranty if the product has not been properly installed; if it has been
disassembled, modified, abused or tampered with; if the electrical cord has been cut, damaged or spliced; if the pump
discharge has been reduced in size; if the pump has been used in water temperatures above the advertised rating, or
water containing sand, lime, cement, gravel or other abrasives; if the product has been used to pump chemicals or
hydrocarbons; if a non-submersible motor has been subjected to excessive moisture; or if the label bearing the serial,
model and code number has been removed. Liberty Pumps, Inc. shall not be liable for any loss, damage or expenses
resulting from installation or use of its products, or for consequential damages, including costs of removal, reinstallation or
transportation.
There is no other express warranty. All implied warranties, including those of merchantability and fitness for a particular
