current project is to run water lines to 6 camps. First camp is 250 feet from the lake, the next is 100 feet more,
And there are 4 more camps further after that. They will all have goulds pumps to pull the water to their own camp.
Should I run separate 1" black hose lines for all or can I run a 2" black hose line and tee off to each camp of course using a foot valve at the lake end for the application.
Thanks for any help.

 

I don't know anything about those pumps but I vote for separate lines.

 

Not a pro on this subject. but wouldn't you be better off with one large pump near the lake and then run your 2" line up to all of the camps, branching as needed.

I'm not sure how multiple pumps would compete using the same source line.

Also not a pro, although I've done several pond supplied irrigation systems. I think the only way having remote pumps like you suggest would work is if all the camps are downhill from the lake so you have head supplying water pressure. Otherwise I think you need a pump at the lake. I don't think there's any way a self priming pump would prime through several hundred feet of pipe, even if the head was less than the 20-25 foot practical maximum.

 

I would use a large pump close to the source (the lake). Include a pressure tank next to the pump.

If you find that the pressure is too low at some of the camps, add smaller pumps and pressure tanks and check valves in the affected camp branches (not in the main line)

 

The foot valve at the end of the hose run holds the water in the hose. After you get the pump is primed there is no problem pulling water through it.
You don't want to install a pump around the water, in this case anyway.
I have a 1/2 hp pump pulling lake water 250 feet using 1" hose now.
Just wondering if a 2" hose with couplings is better than #6 1" hoses.
It would be cheaper and an easier install. Anyone have experience with this ?

 

You are always better off pushing water instead of trying to pull or suck it. You can generate tremendous pressure and flow rate by pumping/pushing water. But on the inlet side you are limited by atmospheric pressure on planet Earth. But as it sounds like you've found you can suck water pretty far. It's a severe limitation but it can be done.

Whether one or six pipes is better depends a lot on how many pumps will be running simultaneously. I've not calculated the flow resistance but here's a quick pass based on area. A 2" ID pipe has 3.14 square inches of cross section to carry water. A 1" ID pipe has .79 square inches of area. So six 1" pipes have 4.74" of area. If there are only a couple pumps running then the 2" pipe would be better but if all six run at the same time it would be better for each to have it's own line.

 

Ok thank you, that is exactly what I needed.
