rcc344, In the catch cup section of your smart details there is a link to a how to video and just to the right of that there are the catch cup instructions. some cups will collect more water, this is a stet to calculate the coverage of your sprinklers. As long as you follow the instructions, and watch the video you’ll be fine with your readings. For your heads we recommend not mixing sprinkler types on your line. However i’d suggest picking which ones you have more of installed for your smart details.
