Step 11: Try it out
Turn the water on low enough that you get a little spray from all the misters. Check and adjust the direction of the misters to direct the water towards the center.
Turn it on full and look for leaks around the base of the misters. If you find one, you can use a wrap of teflon tape around the base of the mister to stop it.
This project uses 12 misters rated at 10 gallons per hour, for a total of 120 gallons per hour. I don't know how that compares with other water toys, but in an era of increasing water restrictions, getting the most out of the water you do use is a good thing.
