Raising a couple of sprinkler heads

I have two different spots where soil was added, mostly burying two sprinkler heads.
One head is a popup rotary head, placed in the middle of a lawn. The other is a simple spray head that had initially been a couple of inches above ground level in a bed (surrounded by soil).

Here's what I was thinking to raise them:
-- poly cut-off riser for the popup in the lawn. I don't imagine there should be much weight that'll hit it, other than people and a ride-on mower, so that'll let me get it right to ground level and support minor weight at times. I'm going to raise it about 3" higher than it is.

-- a nipple (simple pipe riser) for the other. Its height only has to be approximate (I'm not trying to match ground level) and it shouldn't have to bear any weight. It's going to be raised about half a foot above its present; the existing nipple is about 7" long.

I suppose I'll need teflon paste for the nipple.

Am I missing anything?

Sounds good to me... just be very careful not to get any dirt in the pipe, and if you do you might need to flush the head.

Thanks. One more thought: is it better/easier to add to the existing 7" nipple (with a coupler) or to replace the whole thing?

Depends on how much digging you want to do. Both work.

Nothing wrong with adding onto the nipple. It does make a second point where it could fail if it gets abused, but thats usually not very likely.

Just did a few this weekend, they make cut off nipples, male x male or female x male.

Just measure the depth from current head to ground, cut off slightly less, dig out a cone shape of sod & dirt to the head.

Lightly pack the remaining dirt and unscrew, lift out, install riser, no tape needed, and reinstall.

I'm down to less than 5 minutes per head!

The only problem with them is if you put the head "too high" then a riding mower can push down on the head it can bend and eventually will cut or snap the riser. So watch your height and it will work fine.
