Empty conduits on the property - ideas? - It's not too late yet :)

Immediately bury the pipes. The supply line does not run directly at the edge. This way, you only have to dig up one meter later for the sprinkler. At the spots where you can better estimate, install the sprinkler housings right away. It won't get easier than with a new installation. At the spots where you are totally unsure or for reserve circuits, just let the pipe peek out of the ground at the presumably right spot (about 1 meter) and put an end cap on it. Especially with the new lawn installation, irrigation helps immensely.

Which enclosures would you recommend for the PRS40, 15cm depth?

PROS-04-PRS40 Also overall height and 10 risers

So the one with 10cm stroke. How do you come to 10 risers? I would now have ordered a total of 17 MP2000/3000/strips for the housing for my (your) planning.

by "Aufsteiger" I meant the lift. The enclosures have a total height of 15 and a 10 cm lift. It has nothing to do with the quantity. Sorry if it was unclear.

One more question about the fittings, which ones can you recommend and is there a planner somewhere that shows which ones are needed? Specifically, how do I go from PE pipe to a PRS40 housing, do I need a 90° fitting and an additional hose? How are those from Unidelta?

/EDIT
Found an instruction manual, but you are not allowed to link here (who knows why). Other beginners just have bad luck :-/ Is there a hunter forum where you are "freer"?

What is actually to be said about the assembly units, that is, the set of housing, hose, T-piece, and seals (which are available at DVS)?
