STANDARD LIMITED WARRANTY

Myers warrants its products against defects in material and workmanship for a period of 12 months from the date 

of shipment from Myers or 18 months from the manufacturing date, whichever occurs first - provided that such 

products are used in compliance with the requirements of the Myers catalog and technical manuals for use in 

pumping raw sewage, municipal wastewater or similar, abrasive free non-corrosive liquids. 

During the warranty period and subject to the conditions set forth, Myers, at its discretion, will repair or replace to 

the original user, the parts which prove defective in materials and workmanship. Myers reserves the right to change 

or improve its products or any portions thereof without being obligated to provide such a change or improvement 

for prior sold and/or shipped units.

Start-up reports and electrical schematics may be required to support warranty claims. Warranty is effective only if 

Myers authorized control panels are used. All seal fail and heat sensing devices must be hooked up, functional and 

monitored or this warranty will be void. Myers will only cover the lower seal and labor thereof for all dual seal pumps. 

Under no circumstance will Myers be responsible for the cost of field labor, travel expenses, rented equipment, 

removal/reinstallation costs or freight expenses to and from the factory or an authorized Myers service facility.

This limited warranty will not apply: (a) to defects or malfunctions resulting from failure to properly install, operate or 

maintain the unit in accordance with the printed instructions provided; (b) to failures resulting from abuse, accident 

or negligence; (c) to normal maintenance services and parts used in connection with such service; (d) to units which 

are not installed in accordance with applicable local codes, ordinances and good trade practices; (e) if the unit is 

moved from its original installation location; (f) if unit is used for purposes other than for what it is designed and 

manufactured; (g) to any unit which has been repaired or altered by anyone other than Myers or an authorized 

Myers service provider; (h) to any unit which has been repaired using non factory specified/OEM parts.

Warranty Exclusions: MYERS MAKES NO EXPRESS OR IMPLIED WARRANTIES WHICH EXTEND BEYOND 

THE DESCRIPTION ON THE FACE HEREOF. MYERS SPECIFICALLY DISCLAIMS THE IMPLIED WARRANTIES 

OF MERCHANTABILITY AND FITNESS FOR ANY PARTICULAR PURPOSE.

Liability Limitation: IN NO EVENT SHALL MYERS BE LIABLE OR RESPONSIBLE FOR CONSEQUENTIAL, 

INCIDENTAL OR SPECIAL DAMAGES RESULTING FROM OR RELATED IN ANY MANNER TO ANY MYERS 

PRODUCT OR PARTS THEREOF. PERSONAL INJURY AND/OR PROPERTY DAMAGE MAY RESULT FROM 

IMPROPER INSTALLATION. MYERS DISCLAIMS ALL LIABILITY, INCLUDING LIABILITY UNDER THIS 

WARRANTY, FOR IMPROPER INSTALLATION. MYERS RECOMMENDS INSTALLATION BY PROFESSIONALS.

Some states do not permit some or all of the above warranty limitations or the exclusion or limitation of incidental 

or consequential damages and therefore such limitations may not apply to you. No warranties or representations at 

any time made by any representatives of Myers shall vary or expand the provision hereof.
