portable water pumps..

( good idea - yes, i can setup in the field behind the house using the house well. will do that..)

I assume there's a pressure gauge in the well setup but how will you be measuring GPM? Haven't done it in awhile but do you know how to adjust the pressure on the well? (you may need 70-80 psi or something to blow the water 200' as opposed to maybe 50-60 that you're currently set up for in the house).

BTW - Once you think you have it figured out, rent one the same size for a day and see if it actually works before buying one.

now that I think about it, won't the path of the pipe/hose be a factor, particularily from the up-hill water source? 

funny you should mention this - just got off the phone with my dealer (who spoke directly with honda on the prelim #s i was providing).

based on the #s i provided, honda does not make a pump powerful enough to bring the water up from the dug well with enough pressure to send it 200 ft and into the sprinkler unit.

when the water arrives, it won't have sufficient pressure to water a large enough area.

now looking @ holding tanks, or a professional irrigation system using the spring..

thanks again!

Since the water level in the well is 15' above the sprinkler it should be simple to start a siphon and gravity feed the water to a soaker arrangement. As long as you don't have to lift the water more than 34', it will work. You won't have enough pressure to drive a sprinkler. But that's not necessarily bad because sprinkling wastes water.

A 2" centrifugal pump with a 3hp gasoline engine will flood 2 acres in 30 minutes or less. No need for a sprinkler system. All you need is a flat-ish area or a few little ditches and dams to divert the water as needed. I got one at Sam's Club for $300, and love it. The achilles heel of centrufugal pumps is they are slow to prime. Once primed, they put out a huge volume of water.

I used a 6.5 Hp honda spinning a 3" centrifugal trash pump and it took a good while(several hours) to drain my pond (120 SF-4 feet deep). The outfall from the pump didn't flood anything but sure looked impressive. I would say that the water moved by a pump depends on more than just the HP of the pump and size of the connections. The pump curve for the particular impeller can be very different depending on application.

Mine would empty a pond that size in 20-30 minutes. It shoots with pretty high pressure. I have to be careful to not dig a big hole with the business end.
