Backflow preventers are a key part of any plumbing system. They keep contaminated water and clean water separate by keeping your entire plumbing system running in the right direction. There are a few common types of backflow preventers meant for different types of properties, but all of them do the same basic job, and Nulite and Scheblein’s plumbing teams can inspect, repair, and install whichever unit your property uses.

Backflow Testing in NYC with Nulite and Scheblein
According to New York State law, backflow preventers must be tested yearly by a certified tester, and the test must be signed by a master plumber. This isn’t just to ensure that the water in your home or business isn’t contaminated but also because a faulty backflow preventer can allow your property’s used water to flow back into the city’s clean water supply.
Our plumbing teams are run by a master plumber, and we staff certified testers and plumbers with over a decade of experience. This means we can not only handle backflow preventer testing regardless of the type of unit your property uses, but we can also handle the paperwork promptly so that you are compliant with New York regulations.
RPZ Testing
For many commercial properties with more heavy-duty needs, a reduced pressure zone (RPZ) backflow preventer is used. RPZ backflow preventers are the most expensive and complicated type, but they are also the most durable and stable for more hazardous or high-volume use cases. As a result, businesses with RPZ units need a tester with extensive experience testing and installing them. Nulite and Scheblein’s plumbing teams offer exactly that.
