Increasing Pressure at Sprinkler Heads?
We've decided to bury our irrigation lines this year and used 1" pipe. The water source is a pond; the pump sends the water to a 100 gallon holding tank. We have 7 sprinker heads attached to 1" standpipes along the gardens' edge. The garden is 200' long and 50' wide. The sprinklers are not reaching across the garden (missing by about 3 to 4 '). So here's the plumbing question.... we've been told that if we change the standpipe (about 6' high) from 1" to 3/4" about 2' oput of the ground, the decrease in pipe size will increase the water pressure? Does anyone have any knowledge that will lend an answer before we cut one and try it out?
