We want to help you protect yourself and NYC's water! That's why we offer competitively priced backflow testing and installation services. Let's work together to keep our water safe and secure.
Backflow inspections and installations
We offer affordable backflow testing services throughout the Metro NYC area. Our knowledgeable staff is available to answer your questions about violation removals, backflow prevention, testing, and the importance of keeping your water free from contamination.
Backflow is when untreated water gets into the public system. It can happen any time there is a connection between potable water pipes and other pipes or sources that have contaminated water.
In an unprotected system, water can—and does—flow both in and out of a building or fixture. The backflow is known as back-siphonage. When water service is interrupted in the street or in a building for any reason, there is a pressure drop that can draw contaminated water backwards into the water system.
Backflow preventers, also known as RPZs, protect the city’s water supply from outside contamination.
The devices operate by allowing water to flow in only one direction—whether it is into a boiler, a hair salon, a drycleaners or into the building itself. RPZs are required wherever an end user poses a risk of polluting the city’s water.
Backflow is when untreated water gets into the public system. It can happen any time there is a connection between potable water pipes and other pipes or sources that have contaminated water.
We provide installation services for your water pipes that will prevent the backflow of contaminated water and hazardous material.
Including RPZs (reduced pressure zone), DCV (double-check valves), and DCDAs (double-check detector assemblies).
The penalty for not filing your annual inspection may result in a civil penalty / fine of up to a $1,000.00 and termination of water service.
Continued non-compliance or failure to meet the legal backflow prevention mandate may lead to both civil and criminal action.
We send out annual backflow preventer inspection reminders as well as monthly sprinkler inspection reminders, and Local Law 152 periodic gas inspection reminders.
NYC residents will receive a notification letter in the mail from the NYC EP when your backflow prevention device is due for its annual test.
Our plumbers can fix any problems that you are having with your backflow preventer. We will make sure that the water is not going into the city's water supply. If your backflow preventer does not meet the city's regulations, we can repair it or replace it and pull all the necessary permits.
The following prices are estimated based on average industry prices for parts and labor:
- For very small buildings (1 story) installation should cost between $3,000 and $5,000.
- For small buildings (2 story) installation should cost between $3,750 and $5,500.
- For small to mid-size buildings (car washes, laundromats, small manufacturers) installation should cost between $5,000 and $7,000.
- For mid-size buildings (office complexes, large manufacturers or department stores) installation should cost between $7,500 and $13,000.
- For large buildings (High rises, hospitals) installation should cost between $14,000 and $34,000.
If your property is required to have a backflow prevention device and has multiple water service lines, you must install a device on each line.
If you recently received an order to install a backflow prevention (which has a 30-day deadline), as long as DEP has certification in writing from a Licensed Master Plumber (LMP), that a device is in the process of being installed, you will not receive a Notice of Violation.
Visit your local governments website; specifically the water and sewer section. For NYC residents, call 311 to have your inquiry forwarded to a DEP representative.
