As far as pressure, what you need to do is this...right off the faucet make a T, then run your pipe all the way around your kennels and back to the T. In other words you make a complete loop off your faucet so the pressure is pretty equal all the way around. When I first built mine, I used all PVC, but with time the dogs have chewed and I have changed the drops in the kennels to galvanized pipe from about 5' off the ground to the buckets. At the bottom of each kennel drop put a cap on the pipe and drill a small hole in the cap...maybe like a #50 bit or so. Might take a couple minutes to fill all the buckets, but you should have good pressure all the way around like that. I have drops into 13 pens and have no problems. All my buckets fill at almost exactly the same rate.
Also having your main loop at the top of you kennels allows all the water to drain down once the faucet / valve or whatever controls it is turned off so your pipe can't freeze in cold weather.
