Mark, i'm about to install my own system. Why did you downsize on your pump?

Did not need the HP.  3/4 HP provides more than enough for high demand stuff like my turf irrigation pop-ups and I have large yards, like 10,000 s.f.

What demands do you have?

I just started planting, but my long-term goal is 2-3 acres of nut trees (chestnut, walnut, etc), 1 acre of experimental subtropicals, 2 acres of stonefruits/apples and a small greenhouse. And a small house. 10 year project, so I don't know if i build the pump for that or just to get me through the first 5 years.

I'm leaning towards 15-18 gpm right now and vacillating between a constant pressure pump and a traditional setup with a 5000g tank.

Shane, if you are really going to put in a house, you should check what the rules are for water tanks.  I think houses need 7500 gal tanks for fire fighting.  You don't want to go put in a 5000 gal tank and then have to get a bigger one later.

Good point. Looks like i need 5000 for a house < 1500sf. So i probably would need to go 7500 to guarantee 5000 for the FD. Also there are some requirements about location i wasn't aware of. Might need two tanks...

Have you explored a RAM pump. Might have different name in Europe. Cheap to build, no electricity, carries water up hill and at distance.

I have the Grundfos 1 HP for my Xmas tree op, like 3,000 trees on drippers. Rows 8', trees 6'.  It was more than enough. I figured my output around 18 gpm.  I could open up one of the 600' 1/2 inch poly pipe and shoot a stream 30'.  Trust me, that's what you want.

No tank is needed except for the 2 gal. one that you T off in line being it's a closed system IF it's for your house and the other stuff.  (Not open like in a city)

Who wants to build a pump?  They're cheap, well designed, carry a warranty and come in a 100 flavors.
