GPM Enterprises is first and foremost a services and testing company.  We pride ourselves on repairing meters quickly to reduce downtime. We have a 3 day turnaround time on McCrometer meter repairs and 5 day turnaround time on other brands. We offer a 1 year warranty on all MRP repairs and a 90 day warranty on all other repair types and other meter brands. We also service Waterman and P & R Surge Valves for those using that technology. We also have an extensive parts inventory including Meter Repair Kits to offer McCrometer Certified Service Partners throughout the Midwest.

MRP Repair

A comprehensive Meter Repair Program for McCrometer meters which includes a 1 point Certification. 6 parts are replaced which includes the Register Assembly, Bearing Assembly, Canopy Kit W/Bushing, Drive Cable, Drive Liner and Saddle Gasket. This program comes with a 1 year warranty.

CRP Repair

We also offer a Custom Repair Program. This is done when a meter is not very old or has been repaired recently. An example of this program's use is a McCrometer meter sent in periodically for a certification of accuracy only. This program comes with a 90 day warranty. This type of repair is also performed on meter brands other than McCrometer.

Surge Valve Repair

Beginning in July 2018, we began servicing the Waterman and P & R Surge Valve brands. We buy Waterman Surge Valves when available as some parts are not available. We have a 5 day turnaround time depending on parts availability.


The companies who were trained to become a Certified Service Partner are offered Meter Repair Kits that are boxed together in kit form. The parts included in the kit are the Register Assembly, Bearing Assembly, Canopy Kit W/Bushing, Drive Cable, Drive Liner and Saddle Gasket and all parts are Genuine McCrometer Parts.


GPM Enterprises has a good selection of parts available for those who like to do-it-yourself. We have many years of experience to help you get the part needed to fix your meter.
