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.

Does anyone know a source for valve box kits? A 6-valve set would probably be enough for me, and I don’t really want to spend the 560,- at DVS for a pre-assembled box. It shouldn’t be that complicated to connect the few valves with the couplings, right?

I believe DVS also offers bus kits that you can assemble yourself. However, they are not exactly cheap. But experience does come at a price.
I gathered and ordered the parts from 3 or 4 different shops.
I only ever had 4 valves per box with the option of a fifth one and a compressed air connection. In the end, there was also an outgoing line (without a valve) that leads to a water box.

Yes, they do, but without the compressed air connection, and they are not pressure-regulating, with a maximum of four-way distributors.
Would you be so kind as to list here which parts are needed?

You do not need pressure-regulating valves.
Only the sprinkler housings.

Just the sprinkler bodies.

Really? I would have expected the compressed air connection to be at the front, so that you basically blow through the valves out to the zones. Can a closed valve withstand 8 bar (116 psi) air pressure?
That’s why I thought I would need this:
6-way valve box Hunter PGV with flow regulation and compressed air connection, 25 mm (3/4") Plug & Right-angled Expert (ZS-VB062525CBEXP-VM) from DVS for 560,– not exactly cheap.

PS: My first delivery with the MP Rotators and bodies arrived yesterday – they look high quality, nothing like Gardena.

The maximum pressure does not depend on whether the valve is pressure-regulating but only on the type.
You will never actually reach 8 bar (116 psi). A circuit is always open for draining...
