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

My pool has a separate control system, which I connected via KNX. However, this is mainly for displaying temperature, water levels, and so on—so not all functions are integrated.
If you don’t have a control system yet, take a look at the ProCon.ip.
There are also other control systems that offer a KNX interface.
Of course, it is theoretically possible to implement everything with KNX, but the logic can get quite complex and programming takes a considerable amount of time.
For the pool, I would also prefer an independent standalone solution.
A single bus cable will definitely be sufficient.

Thank you for the assessment. I’m glad I had it installed right away. That way, the electrical wiring can simply be included. Even if I end up only using it to turn the pool lighting on and off from inside or on my phone. A visualization of the data would also be quite useful.
We have now basically completed all the piping. I also glued the pool piping and routed it into the technical room. Wherever there was space, I installed several empty conduits to accommodate the cables for irrigation as well as bus and LAN. Now I’m noticing Hunter’s note that the sensor cable from the flow meter should not be routed together in the same cable duct. At first, this doesn’t sound too serious, but it does disrupt my planning. I had no more space in the core drill holes for additional empty conduits, especially since I already foamed them in. I don’t want to tamper with that because I don’t want to damage the PVC pipes. They have already passed the pressure test by the pool builder. Is it really that critical if I run the two cables together? Will they interfere so much that I won’t get accurate flow readings?
