I am working on a dental office and would like to know if anyone has experience with the issue of backflow prevention for dental offices. The office is located in a large medical office building. A main water line enters the suite. There are 3 operatory chairs (general dentistry, no surgery) and a water line will come off the main line and serve two of the chairs and a second line will feed the third chair. An RPZ Backflow Preventer will be installed at the main line. We are planning to use the Watts 909 Series RPZ. but I am also interested in recommendations.
Does the IPC specifically state that backflow preventers are also required at each individual dental chair? Section 608.3 and 608.16.9 seem to suggest they are but seem a little vague.
The manufacturer of the chairs has written “ that while they (the company) has found a way to build a backflow preventer into its unit, its approval is precluded by regulation standards which control valve location and size of test fittings.
I appreciate any input
Thanks - Donald
