DIY sprinkler zones

I've done plumbing before so it should be much of a problem.
I really don't think it would be that much of a price difference between in ground or above. Mainly just more work.

Brian, it would be great if you could share how much the project will end up costing you. I don't mind a lot of work, it's just not something I can put a lot of money in it.
I have an acre, and probably about 50-75% needs to be watered.

It was not hard to do - took me a 4 day weekend (Memorial Weekend) start to finish. Costs were under $1000 (don't remember exactly). Biggest expenses were the Controllers (2 stand-alone units that kept track of when to water and how much, etc), and the Valves (10 of them around $50 apiece I think). Piping and sprinkler heads were pretty reasonable.
I was very satisified with the results - and it wasn't hard (other than digging the trenches). I used to love to turn on the sprinklers and watch them work! I used Rainbird to help with the designs but in the end I used my own (a derivative of theirs).

unfortunately I didn't take any pictures - sorry!
under $1000? That sounds pretty good. Did you happen to take any pictures during the construction process? How deep/wide did you dig the trenches? How did you connect the system to your house? Thanks guys!
trenches were dug about 6-8 inches wide, and about 1 foot deep. (I live in NC and freezing is not a big issue. Check where you live how deep you should go. Remember to use bleed valves (to drain the lines - these are cheap (~$1)). I rented a trencher to dig the trenches. Remember to get your buried wires marked!
I connected it to the main water line into the house. Now they have seperate meters/connections here you can purchase (from the water company) just for sprinklers so you don't pay sewage on the water. These seperate connections aren't cheap - break even is about 3-4 years.
Great website Brian! (I have a couple sprinklers in my new house I have to go replace. That's one advantage of putting one in before, I know how to do it now! )
I bought all my stuff from the local Home Depot.

One more question I guess, I am on a well, would this be a problem?
It looks like I am still going to have to go the cheap route for now, but I am definitely bookmarking these sites. Thanks for the tips so far.

PVC pipes are very cheap. Depending on the diameter you need, they are about a buck or a little more for a 10 foot section. If you need sprinkler heads, I have a basket full of them in my garage that I bought for a project I never finished........

And freezing ground is a concern where you are, so you'll have to go down deeper with the pipes. You might be better off just putting together a relay-controlled manifold for garden hoses... probably wouldn't be much more than $200-$300 for everything...

Electron, the labor is at least half the cost of an underground. If you have the time, the parts cost isn't all that bad:
Rain8Net serial controller: $120
1 1/2 inch galvanized manifold (Home Depot plumbing parts) 8 zones about $50 in parts. Don't forget a threaded reducer to screw in an air fitting for blowing out the lines with an air compressor.
1 inch poly pipe (no need for PVC) $20 / 100 feet.
Lots of T fittings - about $1.50 each sprinkler head
bags of 1 1/4 inch hose clamps $2.00 per spray head (a couple needed per)
Close threaded connectors $1 each spray head
One 1 inch solenoid valve per zone - $14
Spray heads - $14 each
You can put about 6 - 8 heads per zone (dependent on how much water supply you have)
7 strand sprinkler wire $14 / 50 feet
anti siphon valve (for connection to domestic water supply) $25
If lake fed supply: pump (1 1/2 hp) $150
low voltage to 220 volt relay $35
High pressure cutoff switch $22
Intake filter - $80
Check valve - $30
Various other plumbing - $40

In some cases, water can leak back into the system through puddling at the heads during a winter rainstorm/early thaw and refreeze. It may not be worth the effort and expense to install underground sprinklers in his area if this will happen. I suggest you check with a neighbor or the local golf course and see what their installaiton and experiences have shown.
Heck, I live in south Florida (no freezing here), but keeping the head on the pipes around here is the most annoying part of the underground system. If anyone trips or kicks one, a car or lawn tractor runs over one, they usually pop right off their plastic threads and then you have a fountain... ;-)

General wear and tear usually requires replacement of a couple heads every couple years. Nothing too major (my last house, I went 4 years without replacing anything). However, every spring you need to turn'em on and see what happens. Usually have to unbury a couple, and lubricate a couple more.
However, what huggy said is right - between a car and a sprinkler head - the car will always win. I've never had a problem with mowers or people accidentally stepping on them causing them to break.
