I use one of my zones to refill my pool. I measured the open flow and it is 6 gallons per minute, which is 1,386 cubic inches per minute, or 83,160 cubic inches per hour. I tried to create a custom nozzle to track how much water I am using, The closest choice is an “Emitter”, and of course in trying to look this up, my app created a new nozzle that I cannot delete. Anyway, in trying to change the “PRECIP” to 83,160 in/hr, it does not save and defaults back to 2.01. Seems like a pretty simple fix to add some type of open water source nozzle. A lot of folks I know have their sprinkler system tied to their swimming pools to refresh during the summer months.
