ᐅ Water Ingress Through Ventilation System: What to Do and Liability Issues?

Hello respected community,
this topic has probably been discussed before, but I couldn’t find anything specific.

We moved into our newly built house in September 2018 and are very satisfied.
During the recent storms, however, we repeatedly experience water ingress through the decentralized ventilation system on the weather-exposed side.
The builder keeps reassuring us by saying “force majeure,” and the construction company is unresponsive.
We have never encountered this problem before, only since the recent storms (Sabine, etc.).

What is the situation here regarding liability and responsibility?
We have now privately purchased 4 of these weather protection covers for a mere 260.00 €.
Luckily, we only plastered the interior walls, not wallpapered.

Can you help me with what we can do here?
Thank you for your support.

Best of luck
Maik

I don’t find this entirely clear and it’s the first time I’ve heard of such a case. A bit of wind is nothing unusual, and one would expect the devices to withstand such an event.

Are only devices on a specific side of the building affected?

I have read the installation manual of the Lunos e2 as an example. It mentions that the cover caps are designed to be rain-resistant. In exposed locations, "additional weather protection measures may be necessary." Heavy rain is mentioned specifically.

However, the pipe inserted into the core drill hole must be sealed all around and (of course) installed with a slope outward. That’s something that could be done incorrectly.

Have a professional come and inspect the installation, or just put weatherproof covers over it and that’s it.

I would guess it’s just personal bad luck. If the hurricane had torn off your roof, the roofer wouldn’t be at fault (assuming the work was done properly).
Was the ventilation system installed correctly, or are there construction defects? Sounds like the answer is no in your case.

Yeah! I see it the same way. The terms "client" and "building contractor" confused me.

Hello,
Thank you for the feedback. Only the ventilation systems on the windward side are affected. After yesterday’s storm, the interior walls were wet again, despite the weather protection covers -.-
Couldn’t the construction company have done something beforehand or at least warned us about this possibility?

Did the roofer warn that roof tiles can be blown off in a storm? Or the bed salesperson that the bed might catch fire if you fall asleep with a cigarette? Or the kitchen salesperson that the drain could clog if you pour food scraps down it? And so on.
You’re really a sweetheart...

Unprofessional comments are, of course, extremely helpful.
I have no idea what your problem is—I openly share my questions and concerns here and receive ridicule in return?
Not bad, respect.

I thank those who simply wanted to give me objective advice and can accept that I am not an expert.
I thought this was a forum with mature people, my mistake.
