A gated Y valve.
I would say no. They shouldn't be charging anything but a hoseline.
you have a gas hoseline or other type leak. fix it!
10 feet, dont park near it unless you want a hoseline run through your car.
If you don't have a solid handle on algebra, you'll struggle (and possibly fail) firefighting hydraulics. This stuff isn't hard, but you'll need to approach it studiously. You may not have to apply the calculus to become a good firefighter, but you'll need to be able to do some figuring (and in your head, too) to calculate flow rates and capacities and such. This knowledge will be tested on the exams, and, most importantly, on the fire ground when you'll have to think on your feet. Dig in now and master the essentials. You will be a weak link in the chain if you do not, and it is easy to become part of the problem in an emergency situation. Which is a dangerous irony when you arrive at a scene with the intent of being part of the solution. only the most bravest people can do this job. I could never do this job because im a wimp
With a small standard screwdriver CAREFULLY pry out the nozzle, then disconnect the hose from the nozzle. Blow compressed air back through the nozzle from the spray end towards the hose end. DO NOT attempt to use a pin or small wire! While the nozzle is off the car activate the rear washer switch and make sure the hoseline is clear and pumping fluid. If not - your trouble probably lies with the washer pump itself. Hondas have two stage pumps but both run off the same pump motor. Even if the pump motor runs, if nothing comes out the rear hose, the rear pump mechanism has failed. I had this happen to me on my CR-V, and it requires the replacement of the entire pump assembly.
