Can emitters be installed in 3/4″ poly tubing or is 1/2″ the only size that emitters can be installed in? I would like to run a quantity of (4) 3/4″ mains approxiamateely 275′ long with approxiamately 30 to 40 emitters per main. Does this sound do able?

You contacted me about answering question for your client who had RD-600-EXT Controller with 4 sprinklers on 4 stations. but in manual mode #1 station no turn off but other 3 stations work fine.
Ans: This is a common problem that nearly always arises from a faulty solenoid valve adapter, in this case the one on station #1. It has improper or faulty internal or external bleed screw function which can usually be corrected by reference to solenoid installation manual. There is no reason to suspect problem with the RD-600. It always good to read the manual on the RD and be familiar with resetting the memory, etc. Exchanging wire contacts between station #1 and #2 would prove faulty solenoid as #2 station would then malfunction. Good question! OWL

Recently had pool installed which destroyed 5 zones. Installing 5 new zones by tying into existing trunk line & wiring, should be simple. Who ever installed existing system did not use color coded wire, so I am trying to find my common, but I am getting 24v reading on all 5 wires with control box in off position. Why is this?
