OT Plumbers, why are businesses having to put backflow preventers in now?

What is the issue they are trying to prevent? Why only businesses? Why do they need to be checked every year?

just another permit required by local governments to make money off of businesses...my best friend is a plumber and back flow certified...makes a killing doing these inspections...

we always had to put them in then have them inspected for underground sprinkler systems

I think in the NOLA area residences will need them in the next few years. I think it was easier to impose this on business first.
It makes a lot of sense to have back flow preventers on plumbing in flood prone areas.
As flood waters can easily get into the water supply.
When I install new gas appliances, I ALWAYS use a one way fitting so that water can never back flow into the gas lines.

That explains why the sprinkler systems had them first. I guess it's a straight shot for rain drainage to get back into the drinking water.

I have one on my underground sprinkler system. The valve is above ground on the preventer. The mf'er was leaking everywhere after a freeze and I got a crash course on the setup. COme to find out the manufacturer has 2 options on the part that freezes, one made of metal and one made of plastic. Mine had the plastic!!
For a whopping $7 the valve could have come with the metal internal part..unbelievable! Why even off the other plastic version?
Anyway, I'm led to believe it is to protect your internal pipes in you home from a situation where pressure created from an external force could reach a small pipe in your wall.
I did not know it was needed on every home, I'm under the knowledge I had mine only because of the sprinkler system. fyi...Lafayette home built in 2005

How would water get into a gas line?
Posted on 9/26/14 at 10:33 am to CootKilla
Flood water causes ground erosion breaking gas line. Gas is cut off allowing flood water to enter gas line.

It 's my understanding that swimming pool outfall pipes which drain into municipal sewer systems must also have a BFP on them by code.

DHH requirement for most types of businesses/developments. BR Water also requires them where you tap from their main.
The municipal line can sometimes experience a reduction in pressure. If the pressure in the private line exceeds that pressure, water will backflow from the private line into the municipal line. If the water in the private line is contaminated, then it will contaminate the municipal feed. This actually happened in New Orleans last year.

an oven under water in a flooded house.
Not all gas appliances have electronic solenoids to shut off flow.

Water in gas lines was a huge deal for a couple of YEARS after Katrina in Orleans Parish. It really messed with restaurants - the water would bleed through a gas range burner and foul up the orifices.

Regardless of who says what
this is the correct answer

yes. most commercial ovens have a 3/4" to 1" gas line that feeds off of a 2" line.
There is no shut off, besides the gas line shut off valve. If the shut off valve is open, then water will back feed into the gas lines, as the water pressure will quickly be higher than the gas pressure.
Commercial ovens have pilot lights that are always on. It's not like most home ovens used now, that have electronic solenoids that only open and let gas through when they draw 3.2 amps of current.

Had one on our house in Florida and they had to be inspected every year. Thing started leaking one summer and flooding the yard. I hated that stupid thing.

Uh, requirement to put them in has been around for about 20 years.
Yearly check are pretty new.

I have the metal one and it cracked in half after the freeze last year. Wilkins I believe.
I bought all the internal parts, replaced everything, turned the water back on and still leaks like a sieve. Been shut off since.
