zone of 3 3500's, 2 are fogging badly

I don't know my GPM or pressure. I just installed 3 3500's in a zone. Two are fogging very bad. These two are 'inline'. The third is working perfectly, it has it own run of the main zone line. All have the same nozzle.

Is putting the two inline/piggyback causing the problem?

I think I found the problem :whistling:


Seriously, though, you want to make certain you are matching the heads installed to the supply that feeds them. Not enough flow can mean excess zone pressure and that is where the fogging comes from.
