ᐅ Conduits on the Property – Any Ideas? – It’s Not Too Late Yet :)

Hello house building enthusiasts,

My civil engineer is starting the groundwork now (gravel slab for the house and garage). Since he is making the gravel slab up to the property boundary, I’m concerned it might be tight for running electrical cable to the front and back gardens. Additionally, I’m planning an irrigation system, and the water hoses will need to be routed accordingly.

Would it make sense to have the civil engineer install conduits directly, so I can later lay underground electrical cables and PE water pipes without having to dig again? I’m thinking especially about areas without topsoil cover, like the garage and driveway.

Do you have any other tips on what I could implement at this stage?

The house is built without a basement, and the garage has strip foundations without a slab.

Thank you all.

Are you not planning to bury 32mm (1 1/4 inch) piping? The valves should also be 32mm (1 1/4 inch) in that case. Otherwise, you will create a bottleneck, and the flow rate will be significantly reduced.

You’re right, supply line 32mm (1¼ inch), outlet 25mm (1 inch).

Alright, let’s get started:
1 x valve box with protective cover, square shape
6 x Hunter solenoid valves PGV-101G-B
7 x connectors for DA-25 pipe (25mm / 1 inch)
6 x double nipples, both ends 1 inch
3 x cross water distributors 1 inch
1 x end cap for the water distributor

What I’m uncertain about now is the air pressure connection – what does such a connection look like and where is it installed?

/EDIT
Okay, I just noticed that the DVS sets come either with 25mm (1 inch) or 32mm (1¼ inch) inlet and outlet, no mixed sizing. That’s another reason for DIY.

It is also installed on the manifold at the valves. It looks more or less like a water connection. There is a valve before it.

So, are you using only DN25 pipes for your circuits? That might cause flow restrictions, right? Have you designed it to ensure it works properly?

I have installed 25mm (1 inch) PE pipes, yes. For the supply line to the valve box, I would use 32mm (about 5m / 16 feet). I'm still undecided whether to use two 3-valve boxes with a T-piece from the main line or to connect everything to one box.

You had recommended installing 25mm (1 inch) pipes throughout.
Great, I just realized that DVS sent me the wrong swing joints... 3/4 inch (19mm) on both sides...

That's right. So I'm surprised that you still choose the 32mm (1.25 inch) valves just because of 5 meters (16 feet). It doesn't make much difference. The 25mm (1 inch) valves are suitable in this case. I think I confused you with @denz., who installs dn32 everywhere.
