RPZ Backflow Preventers

for Commercial and Multifamily Use

Backflow device

RPZ Backflow Preventer stands for Reduced Pressure Zone. The device has a series of check valves that control the direction that water can flow, and a pressure chamber that can be monitored for pressure between the valves. It is designed to protect public water supplies.

RPZ Backflow devices prevent contaminated water or chemicals from flowing back into the drinking water supply if there is a sudden or unexpected change in water pressure. This backflow can be ther result of pressure that builds up in a hot water heater or boiler, or reduced pressure on the supply side caused by sudden increased demand (fire hydrant). RPZ backflow preventers ensure that the safety of the public drinking water is maintained.

Per New York City Deptartment of Environmental Protection, RPZ backflow Preventers are required for:

NYC Permit

Drain Cleaning

Drain Cleaning

Common blockages causing sewer backup: Inside pipe with obstruction

  • Broken, cracked or collapsed pipe
  • Blockages – grease buildup, hair, paper towels, other object or other restriction
  • Sagging pipes – preventing normal gravity flow
  • Corrosion – deterioration causing sections to collapse.
  • Leaking joints – broken seals between pipes
  • Root infiltration – tree roots have damaged the sewer line

We use the most appropriate methods to economically fix your sewage and drain blockages.

When warranted, we use more sophisticated equipment and techniques such as video camera inspections to locate problems.

Video camera sewer inspections help avoid expensive excavation and demolition.

Video cameras locate and identify:

Damage • Obstructions • Deterioration • Sagging • Perforation • Collapse

Rapid Response to NYC Violations & Three Day Notices

We send out crews quickly to address violations that have resulted in your receiving a:

  • Three Day Notice from the New York City Department of Environmental Protection
  • Ten Day Notice from the New York City Department of Environmental Protection
  • Cease and Desist Order from the NYC Dept. of Environmental Protection

The Three Day Notices is usually issued when there is a leaking water main service. It requires that:

  • the violation be repaired within a specified amount of time
  • Be verified before repair
  • Be repaired by a licensed plumber. Require that the necessary permits be obtained

The Ten Day Notice is issued if there is a failure to respond to the Three Day Notice. In this case, water service has been shut off and will require the payment of a re-connection fee after the leak has been corrected.

The Cease And Desist Order may apply to defective sewer lines that are causing wash-outs or undermines. There are also other conditions such as unlawful discharge which may incur a cease and desist order from the NYC DEP. A cease and desist order from the NYC DEP will usually require immediate action to remedy and avoid violation fines.

Senid Plumbing and Heating has the experience and ability to address these situations and minimize their impact including:

  • Verify the violation (leak) is on your service
  • Obtain the proper permits for yo
  • Correct the water service or sewer problem
  • Sign Off On Completion of Repairs.
