Hello everyone,
We have decided to install a pool and want an automatic water refill system as well. This means we need water supply in our outdoor storage area, where the pool equipment and irrigation control will be located. Of course, we didn’t consider this during planning and construction, as the desire for a pool and automatic irrigation came much later. Anyway.
The outdoor storage is part of the house but is outside the thermal envelope and has no direct access from the house. Now the question is how to get the water connection into the outdoor storage. We would definitely install a backflow preventer. There are basically two options:
1) The pool installer suggested running an additional cold water line from the utility room on the opposite side of the house into the outdoor storage. We could tap off from there. However, this would require a core drill through the concrete wall and insulation, which I would prefer to avoid. The pool installer says this would pose no problem if the drill hole is properly foamed/sealed afterwards. So neither thermal nor sound insulation should be affected, especially since the outdoor storage already has a door and is otherwise tight.
2) I’ve only recently considered this option. We already have a frost-free outdoor faucet at the front. Would it theoretically be possible to modify this faucet or run a line from it through the garden and the front, uninsulated wall of the outdoor storage to supply the equipment? Or is this not advisable or feasible for some reason? The missing outdoor faucet could potentially be replaced by a water outlet if this works out.

What do the experts say? Is the solution with the additional line harmless and cleaner? Or am I risking creating a hole that wouldn’t be necessary otherwise?
Best regards

In our case, the landscaper would install the 10,000-liter (2,640-gallon) version. Don’t you think that’s too expensive? Around 10,000 € including installation, connection, etc.?Two weeks ago, we received a quote from the landscaper for the Graf XL Premium cistern (10,000 liters (2,640 gallons)) including a heavy-duty shaft cover suitable for truck traffic and other accessories, delivery, installation with excavation, and connection for 23,000 €.We have now ordered the cistern and accessories ourselves, which alone cost about 5,600 €. We will arrange the installation ourselves. For 10,000 €, we would have had it done.

Choose the middle option. It is sufficiently durable.For the cistern pump, I can choose between one that delivers 1.9 m³/h (6.7 ft³/h) at 3.5 bar (51 psi) and another that provides 3.5 m³/h (12.4 ft³/h). The latter costs twice as much at 1000€. The 1.9 m³/h pump should be enough. Would the higher capacity offer any additional benefits?
1.9 is far too low. Have a look at the pump curve. That is at 0 meters (0 feet) head and without pressure.
3.5 is okay.
But check out the large flow under the entry for deep well pump AJ 4 Plus 100/57 AUT 😉
424.37 euros. 6 m³/h (6.6 cubic yards per hour) and 5.7 bar (83 psi) with control system.
This is ideal for a typical garden. That way, you can cover larger areas, compensate for pipe losses, and save irrigation and pump running time.
