Some more random thoughts:

1. Tank system is good if your water system is dirty. It gives particles a chance to settle.

2. If you hook up the system to tap, them pressure is equal throughout the pipes, assuming the pipes are not too small and drip holes are not too big.

3. If you hook up to tap and ridgid long pipes are used, than you may want to consider a "water hammer arrestor" at the end of the pipe. Water hammering can be very powerful and damaging in long pipes.

4. In figuring water pressure in a tank system, it is the height of the water that counts, it makes no difference how big (wide) the tank is.
