Which heads to use

Hi all

I have approximately 400 feet of fenced yard connected to 2 sides of our hoeuse for our 2 St. Bernards. It has mostly natural grass with some cattle mix thrown in. The fence is 5' high with full length top rail. I am not looking for the manicured lawn look. Just dust control and keep some green alive. I want to run some pipe along the top rail of the fence and place sprinklers along the top of the fence rail controlled by individual valves to a given number of heads.

I have 1" PVC underground to the fence, and planned on running 3/4" and then 1/2" for the individual stations of heads. I am on a well and can maintain around 30- 40psi at 12gpm.

I was thinking impact type heads

What type, what spacing, and how many per station?

Thank You
Lew

Don't use any 1/2 inch pipe - you don't have pressure to spare. Three Maxipaw impacts may be all you can manage, but try some, before you lay out the zones.

Thank You for the reply. I will not use any 1/2". Good idea, I will run a test section before doing up the whole thing. I was hoping to get 3 - 4 heads per station, and hopfully about 20' throw.

The other thing to consider is that PVC does NOT like being exposed to the sun long term.

If you have to install PVC where it will be exposed to sun, you should paint it with a light-colored water based acrylic or latex paint that is chemically compatible with PVC.

There is a grade of PVC intended for long outdoor exposures (UVR) but it might be cheaper to paint the standard stuff.
