| Looking to buy a system. Every time I call different companies about pricing they ask which system I want - single valve shutoff or dual valve system. Not sure what the answer is. I have a 440 controller from my sprayer that I will be using. Is there an 'age' break somewhere for these controllers, where the older ones used single or dual valve and the newer ones used the opposite? Or are both adaptable and there is a performance difference............
Please share your thoughts..........Thanks! | |
