We currently have 17 questions tagged sprinkler-system on Home Improvement.
We also have 4 questions tagged sod (though there is some overlap).
Would any (all?) of these be suitable for Gardening & Landscaping?
Should we migrate these as a matter of course?
We have only one question tagged sprinkler-system here, and it's on preventing garden critters from chewing up sprinkler valves. Since (garden) pest control is right up our alley, it was decided that such questions are on-topic.
However, most of the questions tagged sprinkler-system on DIY are related to plumbing issues and are off-topic here. This question on DIY was simultaneously cross-posted here (now deleted by owner) and while it got an answer within 2 hours on DIY, it didn't attract any on G&L and was closed a day later. In this discussion, although a "consensus" wasn't reached, the general opinion was that this is either off-topic or maybeish, but better off at DIY.
This question though, is very much on-topic and would be a good fit here. This is also one of the 4 tagged sod. Of the other three, these two are on-topic here. The former has a well upvoted accepted answer so, I think it's best to leave it there. We can take the latter, as the answer is not really an answer and might have a better chance of being answered here.
Generally I think these types of question are good for this site. Yoda's answer goes into more detail.
Main reason for this answer, though, is to point out that sod is a terrible tag from a British English point of view. I had to guess at its meaning and double check with Google. It just looks agricultural at best; at worst it looks like a joke tag. turf is used in UK English (& elsewhere?).
If turf is even half-way understood by North Americans it would be a much better tag/master tag for this type of question.
