HYDROMATIC warrants to the original consumer purchaser (“Purchaser” or “You”) of HYDROMATIC Sump
Pumps, Effluent Pumps, Sewage Pumps (other than 2-1/2"), and Package Systems, that they will be free from
defects in material and workmanship for the Warranty Period of 36 months from date of manufacture.

Our warranty will not apply to any product that, in our sole judgement, has been subject to negligence,
misapplication, improper installation, or improper maintenance. Without limiting the foregoing, operating a
three phase motor with single phase power through a phase converter will void the warranty. Note also that
three phase motors must be protected by three-leg, ambient compensated, extra-quick trip overload relays of
the recommended size or the warranty is void.
Your only remedy, and HYDROMATIC’s only duty, is that HYDROMATIC repair or replace defective products
(at HYDROMATIC’s choice). You must pay all labor and shipping charges associated with this warranty and
must request warranty service through the installing dealer as soon as a problem is discovered. No request
for service will be accepted if received after the Warranty Period has expired. This warranty is not transferable.
EXCEPTIONS: Hydromatic Special Application Pumps, Battery Back-Up Sump Pumps, Filtered Effluent
Pumps, Grinder Pumps, and 2-1/2" Sewage Pumps are warranted for a period of 12 months from date of
purchase or 18 months from date of manufacture, whichever comes first.
HYDROMATIC SHALL NOT BE LIABLE FOR ANY CONSEQUENTIAL, INCIDENTAL, OR CONTINGENT
DAMAGES WHATSOEVER.
THE FOREGOING WARRANTIES ARE EXCLUSIVE AND IN LIEU OF ALL OTHER EXPRESS AND
IMPLIED WARRANTIES, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE FOREGOING WARRANTIES
SHALL NOT EXTEND BEYOND THE DURATION EXPRESSLY PROVIDED HEREIN.
Some states do not allow the exclusion or limitation of incidental or consequential damages or limitations on
the duration of an implied warranty, so the above limitations or exclusions may not apply to You. This warranty
gives You specific legal rights and You may also have other rights which vary from state to state.
This warranty supersedes and replaces all previous warranty publications.
