Most sprinkler systems I've seen or dealt with have T's installed in
the lateral PVC lines with the opening pointing up and the sprinkler
heads screwed into that.

I just dug up part of my sprinkler system as I want to move a few
sprinklers to add a patio. The way the builder put in the sprinklers
(pop-ups) was with the a threaded T opening to the side, an L-shaped
adapter screwed in with about a foot of black flex tubing running
(parallel to the white PVC pipe) to a vertically oriented L joint and
the sprinkler head screwed into that.


Is this a very good installation method? A very bad one? Or just a
strange way of doing it? One plus is that it would seem to allow for a
lot more flexibility in placing individual sprinklers. It would also
seem to cost more for a new install and this builder was not known for
spending on quality, to be diplomatic, hence my consternation..

TIA

It helps when installing.

That method of installation is used to help preven damage when weight of
some kind comes in contact with the sprinkler head. It allows for some
"give" to the system.

I use it in my home installation.

The flex tubing is to keep from breaking your pipe when the mower runs
over a sprinkler head. We put in a few of those when hubby did repairs
on our old, neglected condo's system.

It also allows you to install taller sprinklers than the pipe is deep. My
system is only 6" deep allowing for 4" popups for the most part. That
dosen't get the head above an uncut lawn sometimes. I plan to change to
that configuration so I can use 8" popups and gear head sprinklers.
