boosting water pressure????

Just finished installing one of the frostfree hydrants in the back yard. It's about 150 feet away from the utility room where I tied it in. Flows pretty good but doesn't have a lot of pressure (or is that normal for these things?)....
This is city water.. Is there a possibility of boosting the pressure without tearing everything out and spending a bunch of bucks??? Whatever I use will have to be bought here, but if someone could lay it out for me and tell me what I need, it'd help...

Thanks, Dave
 
Yes. Unless you have a big supply line. Me and the cows are about a quarter mile from the main city water line, the boss is another quarter mile past me. When I turn on one hydrant to water the cows he has a little water, when I turn on two hydrants, he doesn't have any water at the house.
 
Try installing a large pressurized tank into a "T" fitting very close to the hydrant. Have to enclose it from freezing though. Hydraulic or water pressure (same thing) is just like electricity, the longer the run the more resistance you'll have and loose psi/voltage in the system. Again water will seek the path of least resistance like electricity will, this is why your boss has no water when you turn on other faucets. Just my 2 cents worth.
 
Dave, Make sure the handle is pulling the rod up the maximum distance. My son kept complaining about low pressure at his frost proof hydrant. I loosened the adjustment screw and made it pull upon the rod more. Now, plenty of water and pressure.

Oh, by the way, he is about 800 feet from the well.
Raise the handle up, loosen the screw, lower handle a bit and tighten screw. Then see if you have more water.

That makes sense and I'll try it tomorrow.... Just got aggravated with it today.Didn't rain til I got to working in the hole and it poured til I got it all braced and covered. I was just a liiiiiiittle bit cranky when I got done....

What's your flow rate?

My hydrant is 150 ft from house. Well is 50 ft to house. 200 ft of pipe. I get 12 gallons per minute from hydrant.
1/2 hp pump in well.

I’m wondering if you have a leak somewhere. I would turn the water off at the source and see if there is any brief pressure at the hydrant end. I ran water 200 yards for an outside hydrant using city water and I can't see any difference in pressure. I'm also wondering how you plumbed it. I ran 1" pipe until I got 20' from the hydrant and adapted down to 1/2". 150' isn't that far for water anyway. You could have run all 1/2" and not noticed much difference in pressure. If there is no leak I would guess there is some defect with the frost/free hydrant.
 
I had a problem like that in a hydrant, turned out to be the seal in the bottom of the hydrant. Try to adjust it from up top
 

OK........ no problems... Adjusted the valve a little but didn't do much for the pressure but the volume is there.... actually better than the faucet up front by a little.. guess it's just the size of the hydrant pipe and the opening that makes it "look" slow???
