You are welcome
One thing to watch for with the PGM:

It doesn't take much dirt in the screen to make it stop turning. If one of them stops turning, check the screen by unscrewing the drive from the body. You can do this without digging it up if you are careful.

If the screen is clean, take it back to where you bought it, the warranty is AWESOME.

If you only need about 20' try this head. Hunter PGM. We use them occasionaly on clients that do not want to spend the money to redo the lawn but want better coverage. Does not take much pressure or VOLUME (more importantly!) to do what you want. YOu might give them a shot.

As for Jess STryker, email me, you might have better luck, I have found som flaws in his tutorials!

Rotor head work best at 50 psi at the head.
Spray heads are designed to function best at 30 psi

Most Rotor heads used for watering homes can throw 25 to 40 feet (radius).
Spray heads can throw water a maximum distance of 18 feet (radius).

Impart rotors can work better at lower pressures than the normal close case gear driven rotors. The Rain Bir4d R-50 works better than any other rotor at low pressures.

Having the valve at a slightly higher elevation does not give you enough pressure increase to consider unless the drop is significant from top to bottom.

There are low volume NOZZLES that you can use for some hunter heads, as well as rainbird, and toro. Spray heads do take less pressure to run, but there is not a nozzle that can throw 20 ft. maybe about 18 though. The downhill question....It won't significantly increase the pressure, but it will maybe a little. The pressure part for the impacts and the rotors...It really depends on what nozzle you use for your heads. Here is a good webpage for beginners: www.jessstryker.com tells you everything you need to know about irrigation.

what is a good low volume lawn head?

Im running 1/2 copper pipe,I don't have all the pressure in the world...is there a good hunter low volume rotor head that can throw between 20 and 24 ft?

also, do spray heads take alot less pressure rotor heads to run? is there a spray head that can throw 20 to 24 ft?

I have all my line in the yard running down hill,valve box is at the highest point,so will that help my pressure?

also,do rotor heads take more pressure than inpact rotors?
