DGM Industries


NYCDEP / DOH / NEWWA Certified Backflow Testers

We are here to provide a service to keep our water safe from toxins and contaminants. Backflow Preventers are installed to make sure that no chemicals entered our drinking water, yet must be maintained annually to assure its function. We provide this service, as well as any repair needed to keep your device running properly. 


Repairs and Maintenance

Occasionally, a Backflow device will fail the inspection and need to be opened to check for what is causing the issue. We perform this service for our customers, to avoid a much more expensive valve replacement. For our contracted customers, we offer a 5 year Overhaul. This includes the cleaning, and eventual replacement of all rubber components and check assemblies.


Customer Satisfaction Guaranteed

We serve both residential and commercial clients and offer a variety of money-saving solutions. We combine our use of the highest quality parts and equipment, and our dedication to delivering exceptional work to provide you with satisfactory service.


An update for customers during Covid-19 situations

Due to greater restrictions on movement in the NY/NJ area, we are limiting our work as of now. We are not doing any regular testing for at least two weeks, but will restart once we determine it is safe for our employees. We are still available for emergency situations, so contact us at 516-398-2829 if you need help
