Running a leg off a yard hydrant

[GunMonkeyIntl]

I have a yard hydrant right at my well head. My garden is about 100 yards away, and I would like to be able to get water over there without having to run 300' of garden hose, moving it every time I mow. So, I want to put in another hydrant over by the garden. Though the existing hydrant is right out by the well head, it's plumbed out from the pressure tank in the basement.

The plan I have floating in my head right now is this:

1 - Cut a trench below the frostline from next to the existing hydrant out to the garden.

2 - Run a sprinkler line in the trench.

3 - Put in a new hydrant on the garden end, and an up-pipe with a threaded fitting on the end by the existing hydrant.

4 - Install a manifold on the existing hydrant, plug one outlet (when I'm not using it, and hook the other end to the up-pipe with a short length of hose.

Is this crack-pot? I considered cutting into the existing hydrant's underground line with a T and running the new line off of that, but was concerned that I wouldn't have an easy way to clear it for winterizing.

well, if its just for the garden and it where me I would just dig down six inches and lay some pex and have a facet on each end. use a washer hose to connect it to the hydrant.

Fellow Crack-pot. Check me on this.

I have 600 foot central line that runs down hill all the way from the barn to the pasture. The line is 3/4" schedule 160 black pipe. I have several Plasson valves in the line that I can plug into with a barbed riser and garden hose. I want to expand on both sides of the central line to make paddocks.

I just ordered and received nine more valves, "Ts" and risers with the barbs to connect the hoses when and where I want to.

Here is where it applies--I will "plow in" a water line a hundred feet from the barn hydrant. This line will have a Plasson valve on each end. I will come out of the barn with a short hose from the hydrant to a Plasson value. When I want to water at the garden or spray weeds around the barn yard and homestead, I will just plus in at the other end. The lines will only be about eight to ten inches deep and will drain by gravity at the lowest end with a valve opened. All of the fittings are heavy plastic and are hand installed and tightened.

My central line to the pasture lays on top of the ground in a fence line. I will someday plow it in when I'm sure of where I want it.

You can look on line to see how the Plasson Valve works. You may not need a hydrant after-all, unless you want to use it in the winter.

Tee into the line feeding your current hydrant under the frost line. (Not the hydrant pipe itself, but the line that feeds the hydrant.)

Run a nice size regular plastic water pipe over to the other location under the frost line.

Place a hydrant there.

Done.

You now have 2 hydrants, both drain back to keep them from freezing, and all pressurized waterline is safely below the frost line.

Simple, east, no fuss.

I'm not exactly sure what you were describing, but it sounded complicated? My way sounds like less work, far less work over the years, and actually will work. If I understand your complicated plan, step number 4 will bust your existing hydrant. Garenteed, some year you will forget it 'on' and we will dip below freezing and it will bust. Garenteed.

...and...don't buy a cheap Chinese hydrant. Unless you like to dig the whole twice.

I would also consider planning shut-offs. The more complex your system becomes, the more likely that you will need to take part of it off-line for repair.
