It can, and there is no good reason you can't develop an extensive effective root zone in your soil unless you are sitting on a shallow restrictive layer you haven't told us about.

Funny / swing pipe will cause some what of a pressure drop but not at the 4 to 5 GPM when used to connect heads in short runs.

Water the root zone you have not the root zone you think you should have. A-1 in my opinion is right. Watering 45 minutes in sandy soil as you describe your situation being is not the way I'd go about it. Get a Lincoln moisture meter from forestry products. Water 45 minutes and take a moisture reading. Do that every hour and you will find the next optimal time to water. Then start cutting back on the amount of water being applied until your initial moisture reading of the root zone shows the sweet spot amount in which you water the root zone but don't waste water that is just infiltrating below the root zone. Might also want to consider a fertilizer injection system that puts out a small amount of fertilizer with every irrigation. right now you are in a yo yo situation. You need to eliminate as much of the yo yo you can. Learn to do a cats cradle. (applause for weak allegory of the week)

I'd find a free source of compost and start a regular application program.

Pete, if you want a deeper root zone you have to water past the current root zone depth. I do agree on starting a compost topdress program if the compost is good to high quality.

Here are some pics of the #5 nozzles in the heads. I renozzled about 75% of the system.


You were told that by someone who knows nothing about soil structure. Either ammend the soil or water it the way it needs to be watered.

Unless there are some bargain water rates I haven't heard about, that lawn could easily drink up over a thousand dollars a season in water bills. At some point, even a five thousand dollar well is going to pay for itself.

Lets not lose sight of the fact that if watering the way he is watering was working so well , this conversation would not be taking place.

you do realize that a Maxipaw will spray 35 feet with only 25 psi at the head, and with effective coverage, too

........ Silly boy. Go ahead and compare radius with nozzle output.

I've been randomly following this thread, and would the OP be better off installing a booster pump for the system to help get better coverage?

I understand there might be a design problem, but just thinking out-loud on the easiest fix for this situation.

That and one thing that stands out is the fact that the soil is a sandy soil type. From my experience as a farmboy and irrigating sandy fields is a tough proposition at best. Seems like as soon as our irrigation pivots made a full turn, you just went right back out and turned it on again.

So even with the best designed system, the lateral movement of water is next to none, and getting even growth across the lawn in extreme heat and evaporation days to me seems like a waste of time.
