name and phone number of a nearby

may be obtained by contacting MTH 

Pumps.  In the event that it is neces-

sary to return the pump to the factory 

for repairs, remove all accessories 

attached to the pump.  We cannot 

accept responsibility for their safe 

removal, storage, and return.

All requests for warranty claims 

should be made through the com-

is installed.  Refer to the MTH Pumps 

Limited Warranty statement.  Return

motors, mechanical seals, relief 

valves, or other accessories should
