Ventilation

[Jocu]

Hello

I often find many strange solutions in my house..
I was up on the roof and took the opportunity to look down into the vent.
I see that there's water in the pipe.
It's OK if the rainwater drains down into the sewer, but standing water doesn't seem quite right.
With water in the pipe, the ventilation probably won't work as intended?

There's also a risk of water damage if the coupling can no longer hold tight..

For the water to be able to flow through, it feels like the pipe needs to be sloped all the way…
Not like it's done here, according to the picture??

Hi

I was up on the roof and took the opportunity to look down into the ventilation pipe.
I see that there is water in the pipe.
It's okay if the rainwater drains further down into the sewer, but having it stagnant doesn't feel quite right.

Also, there's a risk of water damage if the joint can no longer hold tight...

For the water to drain properly, it seems the pipe needs to be sloped all the way...

Hi,

I would remove the black perforated pipe lying on the insulation, and place a 110mm drain pipe that you hang up against the roof truss with suitable clamps/bands or similar. This way, there is a straight section so that water does not remain in the pipe in the attic.

Hello!
I'm considering the same solution!
Need to buy some pipes!

Replace the two 15-degree bends on the drainage pipe with a steeper type, like 30 or 45 degrees, to reduce the height a bit, those two 15-degree bends are probably needed for the pipe installation…
