RoyDMercer posted this a few weeks back. I've hung on to it so I'll have
the info when I put in my sprinkler system. Hope it helps, and thanks Roy!

I have well water, and my pressure is pretty pathetic.

When I was pricing out an irrigation system last year, I also had to
include the cost of upgrading my well pump and tank.
However, the plumber explained to me that these upgrades didn't have
anything to do with *pressure*. They were required so that the pump
would run longer, instead of lots of cycling off and on, which would
wear it out the pump.

I tested my gpm at an outdoor faucet: 5 gpm! Terrible.

My problem is, I want to get more radius out of my traveling sprinkler
(haven't commited to the cost of irrigation yet).

So I'm confused about pressure versus flow rate.
Will using a larger diameter hose do anything for me?
