Thanks everyone.

I completed this job yesterday. I used a 1-1/4" x 10' PVC pipe, pulled the garden hose through it and then screwed on my adjustable sweeper nozzle. Then I taped the nozzle good to the pipe and worked it back and forth under the driveway.

why spend more money when it's not needed

I don't see any reason why you would want to constrict yourself to 3/4". If you can make a hole big enough to slide a 3/4" piece of pipe through, then you can make the hole bigger to accept a larger pipe. Just use some black pipe and black pipe fitting (along with a sledge hammer) and make the hole bigger. The bell shape of 1/2" to 3/4" with a nipple on the front of it makes for a pretty good arrow point to force through the hole. From experience, I know that a black pipe 3/4" fitting is perfect for 1" copper pipe.

As long as you design it properly

Wouldn't 3/4 inch work? It'd be a lot easier to get under the driveway.
Can I reduce from 1-1/2" to 3/4" without problem? If so, I'll do that.

What kind of soil do you have? It can make the difference between this being an easy job, and a pain in the rear job. You can review the details of the pains I went through dealing with rock-filled clay here: Tunnel Under Driveway

The thing I found to be the relatively easy way to accomplish going under something was to construct a pilot hole with a piece of rebar and sledge hammer. Then I used 3/4" black pipe tipped with a bell reducer 3/4" to 1/2" transition) tipped with a nipple. I then hammered that along the pilot hole. The pilot hole also helps if you need to use a hose or pressure washer to power through.

I use about 4 feet of galvanized pipe attached to the nozzle then pvc there after. It keeps the pipe in a straight line. It comes out exactly where you aim it.

Good luck!

For a resi on a circle driveway. 1" is fine.

However I recommend to do a flow test on your largest consumption zone by using your water meter to get an idea of how much water the system can handle

Are you sure 3 heads will cut it?

It's best to have Head to Head coverage back to back - every sprinkler head spray touching the next spray side to side and front to back. This of course depends on the situation

Yes, concrete. Around 10' wide where I need to go under.
