Residential and Commercial RPZ Backflow Testing Services

The State of Illinois requires annual RPZ backflow testing to insure your safety by protecting drinking water from harmful toxins.  Marquise Plumbing provides residential and commercial testing, and repair of backflow assemblies.

Our pricing includes device test, paperwork, and test submission. Our mission is to simplifying all your backflow needs and making it an easy and convenient process.  A copy of Pass/Fail results will be left onsite as proof the backflow assembly has been tested.  We will also report the results to the appropriate authority to insure your record is kept on file.
