Backflow Prevention

Long Island Backflow Prevention

Backflow prevention devices are essential in keeping your Long Island household water free from contaminants.  Backflow devices work to separate individual home water supplies and potable water from county or district water.

Some districts deem backflow devices mandatory, requiring that Long Island residence owners install and properly maintain them.  Still, there are many Long Island homeowners who are unfortunately without a backflow prevention device.  We’ve found that some homeowners simply do not know what one is while others, in particularly older homes, may never have had these devices installed in the first place.

Ideally, customers would proactively investigate their home’s backflow device before purchasing the home however that’s where we can help.  With over 80 years of industry experience in installing and restoring backflow preventers, Rebmann knows the sure signs and causes of backflow device failure.

Signs and Causes of a Failing Backflow Device

Since it is extreme water pressure that enables water to stream so powerfully from the tap, a sure sign that something may be wrong with your backflow prevention device, is low water pressure. What are the signs and causes of a damaged backflow device?

  • A damaged, leaking, or destroyed water main line
  • Frozen pipes
  • Unexpectedly high water demand

  • Check the code and know the law: When it comes to plumbing, it’s always best to be informed sooner rather than later, especially when health and sanitary concerns are paramount.  Rebmann can help Long Island homeowners understand the particulars of your county or neighborhood. 
  • Find a plumber who offers a warranty: In the rare event a problem should occur, we believe our customers have a right to feel secure and confident in making Rebmann their choice.  We offer a one-year warranty on all parts and services.
