When I was younger (much younger) I worked for a pest control company in South Florida. I worked in outside lawn spray and we would fertilize, and spray for lawn pests as well as fleas and ticks. We had what I believe was a 500 gal truck with a pump on back. In between sprayings I would fill up at a fire hydrant. Anyone I wanted, just had to find one. We had a water meter on the side of the truck and had to go to the water company to get it read once a month or so... We carried around a permit that made it legal. Just used a wrench to undo the hydrant, filled the truck and then poured in the appropriate amount of chemical. I do not see that practice done anymore, do people still use this method? Is it still legal? I am just curious as I was looking into a busness (not chemical related) that would require water while on the road. I cannot tell you how many times a cop would stop to ask me what I thought I was doing. Turns out few of them knew it could be done so I would always have to explain it to them. Anyone?
