I have a lot of pens, and two rows back up to each other. I have been wanting to put nipple waterers in, but the thought of dealing with long PVC, cutting and fitting it, and making it go to all the pens, with angles, T's, zig zags, I can just imagine the hassle and never put them up. The other day I had a lighgtbulb float over my head (BLINK!) and I though I could just zip tie some old garden hose to the chain link, cut with a knife, split with a cheapo plastic fitting, screw a shut off valve on the end for flushing, viola! Was wondering if anyone else had tried it. Anyone?
