To protect New York City’s water supply many businesses are legally mandated to install and maintain approved backflow preventers to avoid contaminated water or chemicals from flowing back into the public drinking water system. If you do not meet the new requirements you are subject to a costly violation of up to $2,000 and possible loss of business.
Device Installation & Inspection Procedure
The DEP has established the following criteria to install, operate and maintain a proper backflow prevention device:
- First, you must hire a Professional Engineer (PE) or Registered Architect (RA) to prepare two sets of backflow prevention plans for your property. These must be submitted with two application forms to DEP’s Cross-Connect Control Unit for approval. If approved, the DEP will notify you via mail and return a copy of the plans to your PE or RA.
- Your backflow prevention device in New York City must then be installed in accordance with the DEP-approved plans. Installation must comply with NYC Department of Buildings's regulations and requirements.
- Once installed, the device must be tested by a New York Certified Backflow Prevention Device Tester.
- Once testing is completed, a test report must be filed immediately with DEP (within 30 days of device installation). In the event of an improper installation, DEP will notify you or your PE/RA. The device will need to be fixed and then resubmitted for inspection and certification.
- Your backflow prevention device must be properly maintained and will be subject to annual testing and inspection by a certified tester.
Signs Your Backflow Preventer Needs Repair
It's important to be aware of the signs that your backflow preventer may need repair. One of the key indicators is uneven water pressure or extreme fluctuation coming from different taps in the house; this could signify a defect in the backflow preventer. Additionally, uneven water pressure could indicate a leak.
Other symptoms can include cloudy or discolored water and slow drainage, which is indicative of an issue with your drainage system as well as your backflow prevention device. If you notice any of these issues, it's important to contact us to inspect and check for potential repairs or replacements needed—after all, it's better to be safe than sorry when it comes to your pipes and fixtures!
Benefits of Backflow Prevention Devices
Backflow and back-siphonage devices are designed to keep contaminated wastewater and sewage in their proper place and away from areas where they could cause sickness or harm. For example, produce washing sinks are required to have an air gap in their drain line. This “break” in the line keeps a sewer backup from contaminating the sink by allowing the backup to flow out of the air gap onto the floor instead of up the drain pipe and into the sink.
Without backflow prevention in New York City, a sewer backup in the middle of the night might go unnoticed and the next day a restaurant could be washing produce in raw sewage, right inside their produce washing sink. These devices are also used to keep any contamination from the restaurant out of the clean water supply.
Do not delay in calling Maxwell Plumb. If the device is not installed as ordered, a violation of up to $2,000 can be issued.
How Often is Backflow Testing Required?
Backflow prevention devices in New York City require testing to monitor the performance of the device. This testing must be done at least once annually to effectively provide backflow prevention from pollution and contamination. It is important that backflow preventer assemblies are tested and maintained, as malfunctioning backflow preventers can lead to potentially hazardous cross-contamination of a drinking water supply.
The backflow testing process involves examining the backflow preventer for any issues, verification that it is correctly installed, inspecting for any physical damages and verifying its operation under normal operating conditions. By having backflow testing performed at least once a year, property owners can ensure their backflow preventer is functioning correctly and meets all necessary safety and performance standards.
