I tried with sizing all laterals but next message keeps popping out "Unsizeable valve encontered...erroring out" How do i size these laterals and how do i find this valve to fix it?

It seems that the problem is with drip area valves, I have several of them. I have removed pipes lower than 25mm in diameter from the project pipe data list and due to low flow with drip irrigation it seems it cant keep adequate velocity? For pop ups we never use laterals below 25mm but for drip I should make new pipe selection (in pipe data) and add 20 and 16mm? 

More over I cant get anything in runtime schedule- report. it seems it doesnt work at all, or it appears empty. Does this sizeing has to do anything with runtime report ? i get the report without any data...

I would say that the critical analysis has to do much more with lateral sizeing than runtimes...Runtimes are precipitation crossed with number of valves, flow and needed water, it should work without any sizes of the laterals :)

Thank you
