Hi I just helped my friend repair her evaporative cooler that's been sitting for years. She had added another cooler in its place for these last few years. Now that they are both up and running i need to figure out how to add another line to the spigot. This is what I currently have set up. If I had another inlet for another poly tube it would be perfect but I haven't been able to find anything like what I need. So I think I may need to Frankenstein this together. But I'm lost on how. I don't necessarily need two separate valves, one would be okay but I can't find the right pieces to get this done. Help?
