Have just had a short weekend away. Got to site and found that the two vents, one in shower and one above
toilet were open. I KNOW they were shut but thought .....Ok, must have left open. So we double checked on leaving Jurien that they were closed. On arriving
home, the one above the shower was open again. I can assume this is internal pressure related, but to my mind this should be happening. Anyone any ideas or experience. The units have a black knob that basically is turned to open and turned to close.
Cheers

Good morning Toyo.
All windows definately shut as its on our checklist. I'll double
check later today when it's light, but pretty sure the roof vents are rear facing, ie. the rear of vent rises upwards.

Might have to set a video camera up inside the van and see if it shows anything. Bob

Hi Phill, just a thought are the vents fitted correctly, as in opening to the rear of the van.
Otherwise i would agree with Bob.
Cheers Pat.

Hi Phill,
Are these vents the wind up / wind down type as normally fitted in bathrooms of caravans?.
If they are then I think something must be broken. Bruce

Everything looks OK Bruce. As I say, its a new van. I've put in photo to see if that sheds any light on the subject.

I've just had a thought...........maybe the screw at the middle of
the knob needs tightening????

Phill, it looks much like
mine but
mine has a crank like handle. I use a little bit of tension after
mine closes just to ensure there is more friction aginst it opening.
Not too much, about an 1/8 of a turn should do it if possible. Too much may place too much stress on the plastic components.
Its pouring down here at the moment otherwise I would duck out and
check to see if
mine is exactly like yours in its construction.
Try closing it next time and then add that 1/8th extra or whatever you feel is safe.
Cheers, Bruce.

Hi Arsenal Phill
I have just had my van serviced but before driving there Jayco Nowra 1.5 hrs away I checked that every thing was closed locked etc and upon arrival the guys mentioned that the vent was still open I told him that I had and he suggested to give it a good nip to make sure it stays shut.
After its service I drove
home not giving it any more thought but remembered to
check before I backed it into the garage and the vent was closed.
I haven't opened it again but it looks like they have had it happen before.
Cheers Michael

We have a 2004 model van and the same thing happened to our vent. On inspection the raising arm that attached to the vent lid has a plastic washer which is attached by an allumimium rivet. The plastic washer had became brittle due to sun, and the arm had come away from the vent lid. Everthing looked normal and hatch still worked due to gravity, but when the wind blew the hatch opened, because it wasn't attached. I removed hatch winding arm assembly. Tapped out rivet and replaced plastic perished washer with a stainless washer, (ensure correct size washer to fit back through hatch) and replaced the same rivet. all good now.

Based on what you have described, the upwards pressure [Bernoulli's Principle] and the gentle vibration would work together to open the vent and turn
the knob...

Thanks all. I am going to try adjusting the centre screw tomorrow and see if it tightens up. Hopefully this will do the trick. If not, then the agents can sort it out on the first service in August.
