"Brown's reasoning is if above-the-ground backflow valves
are that dangerous that we don't want him showing them,
then they shouldn't be in people's yards."
Stacy Williams, Hillsborough County, FL
Homeowners who pump their lawn water from a pond or lake are being required by the Florida Department of Environmental Protection (FDEP) to install expensive backflow valves.
Backflow valves are an expensive solution to a problem that simply doesn't exist. No one has ever died in the state of Florida from a residential backflow contamination incident. In fact, no one has ever even gotten sick in Hillsborough County (population: 1.2 million) from a backflow contamination incident.
Events have moved quickly. The DEP has revised their regulations in a generally good way although there is still the possibility of RP and DC valves being installed in residential areas. Please read Update #26 for the latest news.
I am totally opposed to the use of RP (RPZ) and Double-check backflow valves in residential areas. I created videos which detail the three methods to contaminate a public water supply using these backflow valves. They can be viewed by clicking: Method 1, Method 2, Method 3.
Because of my total distrust of RP & DC backflow valves, I have creating a series of videos about their many vulneabilities. The files are .wmv files which are compatible with Windows Media Player.
Please view the following videos in order. You may consider some of the videos a bit risque, but please keep in mind that by requiring these valves in residential areas, the Florida Department of Environmental Protection is the king without any clothes. I'm just the kid in the crowd pointing it out.
If you want to contact Van Hoffnagle about the dangers of RP valves in residential areas, here is his contact information:
The DEP planned to have their revised rules all in place by Fall of 2009 but that hasn't happened. They have had to delay their backflow valve rulemaking efforts several times in order to work on federally mandated rules governing other water matters. I suggested to the DEP that in the interim maybe they should issue user-friendly status reports to keep everyone updated and informed. Unfortunately, they didn't care for that idea.
So, I decided to provide monthly Updates:
