Hello all,
I am installing a 525 gal water tank 40-50' up on a hill. The tank will flow water by gravity down to a 4 way manifold that waters my garden. The distance from the tank to the manifold is +/- 600'. Can I use a 1" pvc pipe or will that cause too much friction. Are there any other problems that I might run into using a small dia pipe of 1"

thanks
JIM
