Someone told me about how they "raised the pressure" of an irrigation system by decreasing pipe size.
They told me that an irrigation valve had low pressure because there was a very long run of 1" pipe. They reduced a length of it which they said "increased the pressure".
I'm thinking that they did not actually increase the pressure. They increased the velocity and decreased the gallon-age capacity of the pipe.
I'm thinking that the pressure itself did not change because I think the pressure would remain the same.
I'm not sure if the problem was consistent low flow through the heads or if it was very slow start-up time to get up to speed. Obviously though it was a very marginal situation.
